     SUMMARY OF THE INVENTION 
     Problems to be Solved by the Invention 
     Be aware that according to the technique for producing imaging devices disclosed in PTL 1 and PTL 2, an inorganic film such as an AR (Anti Reflection) film and an IRCF (Infra-Red Cut Filter) film is formed at once on glass sheets of the imaging devices while a plurality of singulated imaging device chips is accommodated in a chip tray. 
     The chip tray is provided with a plurality of openings having substantially the same size as the singulated imaging device chips. Each of the openings is provided with an inward claw and receives a glass sheet of an imaging device being fitted into the opening such that the claw thereof abuts a peripheral portion of the glass sheet while exposing the glass sheet from the opening. The film formation is performed on the glass sheets fixed in such a state. 
     However, the claws fixing the glass sheets each shade a portion of the corresponding glass sheet, creating a non-film region under or around the claw, in which the film formation is not feasible. 
     Accordingly, a possible way to form a film over the entirety of a film formation region over which the film is to be formed is reducing a size of the claws that fix the imaging device chips in consideration of the non-film region. 
     However, although reducing the size of the claws that fix the imaging device chips makes it possible to form a film over the film formation region, the claws having the reduced size can allow the imaging device chips to fall off the tray unless each of the imaging device chips and the corresponding opening are aligned accurately. 
     The present disclosure has been achieved in view of the above-described circumstances particularly to enable formation of an inorganic film over the entirety of the film formation region of a flat surface of a glass sheet in a singulated imaging device. 
     Means for Solving the Problems 
     An imaging device according to an aspect of the present disclosure includes an image sensor that captures an image and a glass sheet disposed on the image sensor. The glass sheet has a peripheral portion provided with a recess. 
     The peripheral portion provided with the recess may be located outside a film formation region of the glass sheet. The film formation region may be a region over which an inorganic film is to be formed. 
     The recess may be in a shape corresponding to a claw on a periphery of an opening provided in a tray for formation of an inorganic film on the glass sheet. 
     The recess may be in a step-like shape. 
     The recess may be tapered and be in a flat surface shape.
 
The recess may be in a curved surface shape.

     An electronic apparatus according to an aspect of the present disclosure includes an image sensor that captures an image and a glass sheet disposed on the image sensor. The glass sheet has a peripheral portion provided with a recess. 
     A method of producing an imaging device according to an aspect of the present disclosure includes a first step and a second step. The imaging device includes an image sensor that captures an image and a glass sheet disposed on the image sensor. The glass sheet has a peripheral portion provided with a recess. In the first step, first grooves are formed in an undiced imaging device along central lines of dicing lines using first blades having a predetermined width. In the second step, the undiced imaging device is diced along the central lines of the dicing lines using second blades having a width smaller than the predetermined width. 
     The first blades may be V-shaped blades. 
     The method may further include a third step, a fourth step, and a fifth step. In the third step, second grooves are formed in the undiced imaging device along the central lines of the dicing lines using third blades after the first step. The second grooves have a depth larger than the first grooves. The third blades have a width smaller than the predetermined width of the first blades and larger than the width of the second blades. In the fourth step, the second grooves are filled with a black resin. In the fifth step, third grooves are formed in the undiced imaging device along the central lines of the dicing lines using fourth blades. The third grooves have a depth smaller than the first grooves. The fourth blades have a width smaller than the predetermined width of the first blades and larger than the width of the third blades. After the fifth step, the second step may be performed to dice the undiced imaging device along the central lines of the dicing lines using the second blades. 
     The first blades and the fourth blades may be the same V-shaped blades, and the first blades and the fourth blades may be different in depth of grooves to form. 
     The method may further include a sixth step of forming an inorganic film on the glass sheet after the second step. 
     The inorganic film may be an AR (Anti Reflection) film or an IRCF (Infra-Red Cut Filter) film.

     10. Configuration Examples of Stacked Solid-state Imaging apparatus to which Technique according to Present Disclosure is Applicable 
     1. INORGANIC FILM FORMATION METHOD 
     An imaging device according to the present disclosure enables formation of an inorganic film over the entirety of a film formation region of a singulated glass sheet. For description of the imaging device according to the present disclosure, a method of forming an inorganic film on a singulated glass sheet will be described. 
     An upper left part of  FIG. 1  illustrates a configuration example of a singulated imaging device (also referred to as a solid-state imaging apparatus)  11 . The imaging device  11  has a three-layer structure including a glass sheet  31 , a resin layer  32 , and a sensor section  33  in order from top to bottom of  FIG. 1 . The resin layer  32  for example includes a transparent resin and bonds the sensor section  33  and the glass sheet  31  together. 
     An AR (Anti Reflection) film  41  being an inorganic film is formed on a surface F 1 , which is an upper surface in  FIG. 1 , of the glass sheet  31  illustrated in the upper left part of  FIG. 1 . 
     More specifically, as illustrated in a lower left part of  FIG. 1 , a tray  51  is provided with arrayed quadrilateral openings  61  each having substantially the same size as the imaging device  11 . A singulated imaging device  11  is fixed in each of the openings  61  with the glass sheet  31  facing downward in the paper sheet of  FIG. 1 . The AR film  41  being an inorganic film is formed on the surface F 1  of the glass sheet  31  exposed from the opening  61  through vapor deposition as illustrated in an upper right part of  FIG. 1 . 
     That is, as illustrated in the upper right part of  FIG. 1  and an enlarged view ex 1  in a lower right part of  FIG. 1 , each of the openings  61  is provided with a claw  62  on a periphery thereof, and the claw  62  abuts the glass sheet  31  of the corresponding imaging device  11  at a peripheral portion of the surface F 1  to fix the surface F 1  of the glass sheet  31  with the surface F 1  exposed from the opening  61 . As a result, the AR film  41  being an inorganic film is formed through vapor deposition on the surface F 1  of the glass sheet  31  fixed while being exposed from the opening  61 . It should be noted that arrows in  FIG. 1  represent the vapor deposition through which the AR film  41  is formed. 
     Be aware that each of the claws  62  protrudes onto the surface F 1  of the corresponding glass sheet  31 . When the AR film  41  being an inorganic film is formed as illustrated in  FIG. 1 , therefore, the claw  62  is likely to create a non-film region in a portion of a film formation region that is located in the peripheral portion of the glass sheet  31 , as illustrated in an upper part of  FIG. 2 . 
     An upper left part of  FIG. 2  illustrates a configuration corresponding to the upper right part of  FIG. 1 . Furthermore, an enlarged view ex 11  of a rectangular portion in an upper right part of  FIG. 2  is an enlarged view of a rectangular portion in the upper left part of  FIG. 2 . A portion of the glass sheet  31  that is located on the left side of a dotted line in  FIG. 2  is the film formation region. However, as indicated by a range Z 1  in the enlarged view ex 11 , the claw  62  protruding onto the glass sheet  31  produces shade, preventing the AR film  41  being an inorganic film from being formed over the entirety of the film formation region whose boundary is indicated by dotted lines. That is, as indicated by the range Z 1  in the enlarged view ex 11 , the film formation method described with reference to  FIG. 1  can leave a region in which formation of the AR film  41  being an inorganic film has been unsuccessful in a portion of the film formation region of the glass sheet  31 . 
     A possible way to solve such an issue is reducing a length of the claw  62  in the upper left part of  FIG. 2  to a length of a claw  62 ′ in a middle part of  FIG. 2  to increase a width of the opening  61  from a width W 1  illustrated in the upper part of  FIG. 2  to a width W 11  illustrated in the middle part of  FIG. 2 , so that the AR film  41  is able to be formed over the entirety of the film formation region indicated by the dotted lines including an end portion thereof as illustrated in an enlarged view ex 12  in a middle right part of  FIG. 2 . 
     However, as a result of the claw  62  being replaced with the claw  62 ′ and the width of the opening  61  being changed from the width W 1  to the width W 11  as illustrated in the middle part of  FIG. 2  to enable formation of the AR film  41  over the entirety of the film formation region, an area of abutment of the claw  62 ′ against the peripheral portion of the glass sheet  31  becomes smaller. Even a slight misalignment of the glass sheet  31  relative to the opening  61 , for example, can therefore cause the imaging device  11  to fall off the tray  51  from the opening  61  due to the claw  62 ′ failing to abut the peripheral portion of the glass sheet  31  as illustrated in a lower right part of  FIG. 2 . 
     2. FIRST EMBODIMENT» 
     The imaging device according to the present disclosure is therefore provided, on an outer periphery of the film formation region, with a recess to be abutted by a claw on an outer periphery of an opening provided in a tray, so that the entirety of the film formation region is exposed from the opening and an inorganic film is able to be formed over the entirety of the exposed film formation region through a vapor deposition process. 
       FIG. 3  illustrates a configuration example of a first embodiment of the imaging device according to the present disclosure that enables formation of an inorganic film over the entirety of the film formation region. 
     As illustrated in an upper part of  FIG. 3 , an imaging device  101  includes a glass sheet  131 , a resin layer  132 , and a sensor section  133  in order from top to bottom of  FIG. 3 , and the resin layer  132 , which is transparent, bonds the glass sheet  131  and the sensor section  133  together. The sensor section  133  includes, for example, a CMOS (Complementary Metal Oxide Semiconductor) image sensor. The sensor section  133  generates an image from light entering from a subject through the glass sheet  131  and the resin layer  132 , and outputs the image. 
     Furthermore, the top of the glass sheet  131  in  FIG. 3  is a surface F 101  including the film formation region over which an AR film  141  (lower part of  FIG. 3 ) being an inorganic film is to be formed. A recess  111  is provided in a periphery of the surface F 101 . As illustrated in the lower part of  FIG. 3 , the recess  111  is in a step-like shape to be abutted by a claw  162  provided around an opening  161  provided in a tray  151  corresponding to the tray  51  in  FIG. 1 . As illustrated in the upper part of  FIG. 3 , the recess  111  is formed as a surface one step lower than a reference surface, which in  FIG. 3  is the surface F 101 , and a level difference therebetween is substantially the same as a height of the claw  162 . 
     Such a configuration exposes the surface F 101  from the opening  161  as illustrated in an enlarged view ex 31  of a rectangular region in a lower left part of  FIG. 3 . The AR film  141  including an inorganic film is therefore formed to cover an end portion of the surface F 101  including the film formation region located on the left side of a dotted line. Thus, it is possible to suppress creation of a non-film region, and reduce occurrence of ghost and flare due to light that can enter through the non-film region. 
     Furthermore, the surface F 101  including the film formation region of the glass sheet  131  is described as having substantially the same shape and substantially the same size as the opening  161 . To be exact, the surface F 101  is slightly smaller than the opening  161  and protrudes frontward from the recess  111  when viewed from an image plane of the sensor section  133 . The imaging device  101  is therefore to be fixed such that the surface F 101  of the glass sheet  131  is fitted into the opening  161  and the recess  111  is abutted by the claw  162 . Since the entirety of the surface F 101  including the film formation region of the glass sheet  131  is thus exposed from the opening  161 , it is possible to form the AR film  141  over the entirety of the surface F 101  through a vapor deposition process and keep the imaging device  101  from falling off from the opening  161 . 
     &lt;Method of Producing Imaging Device in  FIG. 3 &gt; 
     The following describes a method of producing the imaging device in  FIG. 3  with reference to  FIG. 4 . 
     In a first step, the sensor section  133  prior to singulation for the imaging device  101  is attached to a dicing sheet  181  with the glass sheet  131  facing upward as illustrated in an uppermost portion of a left part of  FIG. 4 . 
     In a second step, as illustrated in a second portion from the top of the left part of  FIG. 4 , blades  201  are fixed such that a location of a central line of each of the blades  201  coincides with a location of a central line of a corresponding one of dicing lines for the singulated imaging device  101  and a distance between inner surfaces of the blades  201  is equal to a width of the film formation region. Subsequently, the blades  201  in such a state are then used to form grooves  131   a  in the glass sheet  31  (see a third portion from the top of the left part of  FIG. 4 ). 
     In a third step, as illustrated in the third portion from the top of the left part of  FIG. 4 , the blades  201  are pulled out, and then blades  211  are positioned such that a location of a central line of each of the blades  211  coincides with the location of the central line of a corresponding one of the dicing lines for the singulated imaging device  101 . The blades  211  in such a state are used to cut (dice) the glass sheet  131 , the resin layer  132 , the sensor section  133 , and the dicing sheet  181 . 
     In a fourth step, the blades  211  are pulled out, thereby yielding the singulated imaging device  101  as illustrated in a lowermost portion of the left part of  FIG. 4 . 
     That is, as a result of the singulated imaging device  101  being yielded by cutting the grooves  131   a  along central lines thereof using the blades  211 , opposite end portions of the grooves  131   a  are formed to be the recess  111  in an end portion of the glass sheet  31  of the imaging device  101 . 
     Thus, of the glass sheet  31 , a range excluding the recess  111  is formed as the surface F 101  including the film formation region. The surface F 101  has substantially the same shape and substantially the same size as the opening  161  of the tray  151 . To be exact, the surface F 101  is slightly smaller than the opening  161 . 
     In a fifth step, as illustrated in an upper right part of  FIG. 4 , the imaging device  101  is turned upside-down and placed such that the recess  111  is abutted by the claw  162 . The vapor deposition process is performed from below in  FIG. 4  on the surface F 101  being the film formation region exposed from the opening  161 , and thus the AR film  141  being an inorganic film is able to be formed over the entirety of the surface F 101  being the film formation region. 
     It should be noted that the blades  201  and  211  are dicing blades. A lateral width of the recess  111  may be adjusted by setting a width of the blades  201  to a value approximately six to ten times a width of the blades  211  for the singulation. 
     Furthermore, any film other than the AR film  141  may be formed on the surface F 101  including the film formation region as long as the film is an inorganic film. For example, an IRCF (Infra-Red Cut Filter) film may be formed. 
     3. SECOND EMBODIMENT» 
     Through the above, an example of the imaging device  101  has been described that includes the recess  111  formed in the periphery of the surface F 101  including the film formation region of the glass sheet  31 . According to this configuration, the recess  111  is abutted by the claw  162  of the tray  151 , and the surface F 101  including the film formation region of the glass sheet  31  is exposed from the opening  161 , enabling formation of an inorganic film over the entirety of the surface F 101  including the film formation region. However, the claw  162  may be tapered, and the recess  111  may accordingly be tapered, as long as a configuration that allows the surface F 101  including the film formation region of the glass sheet  31  to be exposed from the opening  161  is achieved. 
     A left part of  FIG. 5  illustrates a configuration example of a second embodiment of the imaging device according to the present disclosure provided with a recess, which replaces the recess  111 , to be abutted by a tapered claw, which replaces the claw  162 . It should be noted that constituent elements in  FIG. 5  corresponding to the constituent elements in  FIG. 3  are indicated by the same reference signs as in  FIG. 3 , and description thereof is omitted as appropriate. 
     The configuration of the imaging device  101  in the left part of  FIG. 5  is different from the configuration in  FIG. 3  in that a tapered recess  111 ′ is provided instead of the recess  111  of the glass sheet  31 . Furthermore, a tapered claw  162 ′ that matches the taper of the recess  111 ′ is provided instead of the claw  162  of the tray  151 . 
     That is, in this configuration, the surface F 101  including the film formation region protrudes frontward from the recess  111 ′ when viewed from the image plane of the sensor section  133 . Furthermore, an angle of the taper of the claw  162 ′ and an angle of the taper of the recess  111 ′ correspond to each other. The claw  162 ′ abuts the recess  111 ′ with the surface F 101  including the film formation region exposed from an opening  161 ′. The AR film  141  being an inorganic film is formed on the exposed surface F 101  including the film formation region as indicated by a range Z 51  in an enlarged view ex 51  of a rectangular range of the left part of  FIG. 5 . 
     As a result, it is possible to form the AR film  141  including an inorganic film over the entirety of the surface F 101  including the film formation region. 
     Furthermore, a width W 31  of the opening  161 ′ is wider than the surface F 101  including the film formation region as illustrated in the left part of  FIG. 5 . It is therefore possible to form, by the above-described configuration, the AR film  141  being an inorganic film also on the recess  111 ′ of the glass sheet  31  over a region that is not abutted by the claw  162 ′ as particularly indicated by a range Z 52  in an enlarged view ex 52  in a right part of  FIG. 5 . This configuration enables suppression of entry of reflected light not only from the surface F 101  including the film formation region but also from directions of side surfaces adjacent to the surface F 101 , reducing occurrence of ghost and flare. 
     &lt;Method of Producing Imaging Device in  FIG. 5 &gt; 
     The following describes a method of producing the imaging device  101  in  FIG. 5  with reference to  FIG. 6 . 
     In a first step, the sensor section  133  prior to singulation for the imaging device  101  is attached to the dicing sheet  181  with the glass sheet  131  facing upward as illustrated in an uppermost portion of  FIG. 6 . 
     In a second step, as illustrated in a second portion from the top of  FIG. 6 , a location of a central line of each of V-shaped blades  231  is made to coincide with a location of a central line of a corresponding one of dicing lines for the singulated imaging device  101  and a distance between inner surfaces of the V-shaped blades  231  is made equal to the width of the film formation region. The blades  231  in such a state are then used to form grooves  131   b  (see a third portion from the top of  FIG. 6 ) in the glass sheet  131 . 
     In a third step, as illustrated in the third portion from the top of  FIG. 6 , blades  241  are positioned such that a location of a central line of each of the blades  241  coincides with the location of the central line of a corresponding one of the dicing lines for the singulated imaging device  101 . The blades  241  in such a state are then used to cut (dice) the glass sheet  131 , the resin layer  132 , the sensor section  133 , and the dicing sheet  181 . 
     In a fourth step, the blades  241  are pulled out, thereby yielding the singulated imaging device  101  as illustrated in a lowermost portion of  FIG. 6 . 
     That is, as a result of the singulated imaging device  101  being yielded by cutting the grooves  131   b  along central lines thereof using the blades  241 , opposite end portions of the grooves  131   b  are formed to be the tapered recess  111 ′ in the end portion of the glass sheet  131  of the imaging device  101 . 
     Thus, of the glass sheet  31 , a range excluding the recess  111 ′ is formed as the surface F 101  including the film formation region. The surface F 101  has substantially the same shape and substantially the same size as the opening  161  of the tray  151 . To be exact, the surface F 101  is slightly smaller than the opening  161 . 
     In a fifth step, as illustrated in the left part of  FIG. 5 , the imaging device  101  is turned upside-down and placed such that the recess  111 ′ is abutted by the corresponding tapered claw  162 ′. The vapor deposition process is performed from below in  FIG. 5  on the surface F 101  being the film formation region exposed from the opening  161 , and thus the AR film  141  being an inorganic film is able to be formed over the entirety of the surface F 101  being the film formation region. 
     Furthermore, as indicated by the range Z 52  in the enlarged view ex 52  of the right part of  FIG. 5 , the above-described configuration allows the AR film  141  to be formed also on the recess  111 ′ over a partial region that is not abutted by the claw  162 ′ through the above-described vapor deposition process. This enables reduction of occurrence of ghost and flare due to entry of light from an oblique direction, such as reflected light. 
     That is, since the recess  111  in the first embodiment or the recess  111 ′ in the second embodiment is provided in the peripheral portion of the glass sheet  131  to correspond to the claw  162  or  162 ′ provided on the periphery of the opening  161  of the tray  151 , the surface F 101  including the film formation region is exposed from the opening  161  or  161 ′, and an inorganic film is formed over the entirety of the surface F 101 . 
     In other words, a similar effect is produced as long as a recess corresponding to the claw of the opening of the tray is provided in the peripheral portion of the glass sheet  131 . Therefore, the shape of the recess that is provided in the peripheral portion of the glass sheet  131  is not limited to those of the recess  111  (step-like shape) and the recess  111 ′ (flat surface shape). In addition to the step-like shape and the flat surface shape, any shape such as a curved surface shape and a free-form curved surface shape is possible as long as edges of the peripheral portion of the glass sheet  131  are recessed or ground off into a shape corresponding to the claw of the opening of the tray. 
     4. THIRD EMBODIMENT 
     Through the above, the imaging device  101  has been described that enables formation of the AR film  141  being an inorganic film over the entirety of the surface F 101  including the film formation region of the glass sheet  31 . Additionally, the imaging device  101  may be enabled to reduce occurrence of ghost and flare due to a factor such as reflected light and multiply reflected light. 
     That is, for example, in a case where the imaging device  101  including the glass sheet  131 , the resin layer  132 , and the sensor section  133  is disposed on a substrate  301  as illustrated in a left part of  FIG. 7 , incoming light, which is indicated by a ray trajectory L 1 , that has entered the glass sheet  131  and the resin layer  132  can enter the sensor section  133  after being reflected by a surface of the sensor section  133  and end portions of the glass sheet  131  and the resin layer  132  to cause ghost and flare. 
     Furthermore, likewise, incoming light indicated by a ray trajectory L 11  in a right part of  FIG. 7  can be reflected by a circuit  311  provided on the substrate  301 , and the reflected light can enter the sensor section  133  from the side surfaces. Also, incoming light indicated by a ray trajectory L 12  can be reflected by the circuit  311  and a surface of the glass sheet  131 , and the reflected light can enter the sensor section  133 . Such reflected light can cause ghost and flare. 
     A light-absorbing black resin section may therefore be formed on ends of the glass sheet  131  to suppress entry of light from the side surfaces, and thus reduce occurrence of ghost and flare due to reflected light and multiply reflected light. 
       FIG. 8  illustrates a configuration example of a third embodiment of the imaging device  101  enabled to reduce occurrence of ghost and flare due to reflected light and multiply reflected light by suppressing entry of light from the side surfaces with the light-absorbing black resin section formed on the ends of the glass sheet  131 . It should be noted that constituent elements of the imaging device  101  in  FIG. 8  that have the same functions as the constituent elements of the imaging device  101  in  FIG. 3  are indicated by the same reference signs as in  FIG. 3 , and description thereof is omitted as appropriate. 
     That is, the imaging device  101  in  FIG. 8  is different from the imaging device  101  in  FIG. 3  in that a light-absorbing black resin section  321  is formed on an abutment surface of the recess  111 , which is to be abutted by the claw  162  of the tray  151 . 
     Such a configuration enables the imaging device  101  to reduce occurrence of ghost and flare, because the black resin section  321  absorbs incoming light and reflected light entering from directions of the side surfaces of the glass sheet  131  of the imaging device  101 . 
     &lt;Method of Producing Imaging Device in  FIG. 8 &gt; 
     The following describes a method of producing the imaging device  101  in  FIG. 8  with reference to  FIG. 9 . 
     In a first step, the sensor section  133  prior to singulation for the imaging device  101  is attached to the dicing sheet  181  with the glass sheet  131  facing upward as illustrated in an uppermost portion of a left part of  FIG. 9 . 
     In a second step, as illustrated in a second portion from the top of the left part of  FIG. 9 , a location of a central line of each of blades  331  is made to coincide with a location of a central line of a corresponding one of dicing lines for the singulated imaging device  101  and a distance between inner surfaces of the blades  331  is made equal to the width of the film formation region. The blades  331  in such a state are then used to form grooves  131   c  (see a third portion from the top of the left part of  FIG. 9 ) in the glass sheet  131 . 
     In a third step, as illustrated in the third portion from the top of the left part of  FIG. 9 , blades  341  are positioned such that a location of a central line of each of the blades  341  coincides with the location of the central line of a corresponding one of the dicing lines for the singulated imaging device  101 . The blades  341  in such a state are then used to form grooves  131   d  (see a fourth portion from the top of the left part of  FIG. 11 ) having a depth extending from an inside of the glass sheet  131  through the resin layer  132  to an inside of the sensor section  133 . 
     In a fourth step, as illustrated in a fourth portion from the top of the left part of  FIG. 9 , the blades  341  are pulled out, forming grooves  351 , each of which is a combination of the groove  131   c  and the groove  131   d.    
     In a fifth step, as illustrated in a lowermost portion of the left part of  FIG. 9 , the grooves  351  are filled with a black resin  371 . 
     In a sixth step, as illustrated in an uppermost portion of a right part of  FIG. 9 , blades  381  having a width smaller than the grooves  131   c , which in other words is a width smaller than the blades  331 , are used to form grooves  131   e  (see a second portion from the top of the right part of  FIG. 9 ) having a smaller width and a smaller depth than the grooves  131   c  in the black resin  371 . 
     In a seventh step, as illustrated in the second portion from the top of the right part of  FIG. 9 , blades  391  having a smaller width than the blades  341  are positioned such that a location of a central line of each of the blades  391  coincides with the location of the central line of a corresponding one of the dicing lines for the singulated imaging device  101 . The blades  391  in such a state are then used to cut (dice) the glass sheet  131 , the resin layer  132 , the sensor section  133 , and the dicing sheet  181 . 
     In an eighth step, the blades  391  are pulled out, thereby yielding the singulated imaging device  101  as illustrated in a third portion from the top of the right part of  FIG. 9 . 
     As a result of the singulated imaging device  101  being yielded by cutting the grooves  131   e  along central lines thereof using the blades  391 , opposite end portions of the grooves  131   e  are formed to be the recess  111  in the end portion of the glass sheet  131  of the imaging device  101 . Furthermore, the black resin  371  is left as the grooves  131   e  in the recess  111 , thereby forming the black resin section  321  in  FIG. 8 . 
     Thus, of the glass sheet  31 , a range excluding the recess  111  is formed as the surface F 101  including the film formation region having the same shape as the opening  161  of the tray  151 . The recess  111  is abutted by the claw  162  with the surface F 101  being the film formation region exposed from the opening  161  as illustrated in  FIG. 8 , allowing the AR film  141  being an inorganic film to be formed on the entirety of the surface F 101  being the film formation region. 
     Furthermore, the black resin section  321  (black resin  371 ) that spans side surfaces of the imaging device  101  is formed on the surface of the recess  111  as illustrated in a lowermost portion of the right part of  FIG. 9 . Since the black resin section  321  absorbs incoming light and reflected light entering from the side surfaces, it is possible to reduce occurrence of ghost and flare. 
     5. FOURTH EMBODIMENT» 
     Through the above, an example of the imaging device  101  has been described that reduces occurrence of ghost and flare by absorbing light such as reflected light and multiply reflected light with the black resin  371  ( 321 ) formed on the recess  111  to span the side surfaces of the imaging device  101 . However, the black resin section may be formed on a surface of the tapered recess  111 ′ described with reference to  FIG. 5  to reduce occurrence of ghost and flare. 
       FIG. 10  illustrates a configuration example of a fourth embodiment of the imaging device  101  enabled to reduce occurrence of ghost and flare due to reflected light and multiply reflected light by suppressing entry of light from the side surfaces with the black resin section or the like formed on the surface of the recess  111 ′ of the glass sheet  131 . It should be noted that constituent elements of the imaging device  101  in  FIG. 10  that have the same functions as the constituent elements of the imaging device  101  in  FIG. 5  are indicated by the same reference signs as in  FIG. 5 , and description thereof is omitted as appropriate. 
     That is, the imaging device  101  in  FIG. 10  is different from the imaging device  101  in  FIG. 5  in that a light-absorbing black resin section  411  that spans the side surfaces of the imaging device  101  is formed on the surface of the recess  111 ′. 
     Such a configuration enables the imaging device  101  to reduce occurrence of ghost and flare, because the black resin section  411  absorbs incoming light and reflected light entering from directions of the side surfaces. 
     &lt;Method of Producing Imaging Device in  FIG. 10 &gt; 
     The following describes a method of producing the imaging device  101  in  FIG. 10  with reference to  FIG. 11 . 
     In a first step, the sensor section  133  prior to singulation for the imaging device  101  is attached to the dicing sheet  181  with the glass sheet  131  facing upward as illustrated in an uppermost portion of a left part of  FIG. 11 . 
     In a second step, as illustrated in a second portion from the top of the left part of  FIG. 11 , a location of a central line of each of V-shaped blades  421  is made to coincide with a location of a central line of a corresponding one of dicing lines for the singulated imaging device  101  and a distance between inner surfaces of the V-shaped blades  421  is made equal to the width of the film formation region. The blades  421  are then used to form grooves  131   f  (see a third portion from the top of the left part of  FIG. 11 ) in the glass sheet  131 . 
     In a third step, as illustrated in the third portion from the top of the left part of  FIG. 11 , blades  431  having a smaller width than the V-shaped blades  421  are positioned such that a location of a central line of each of the blades  431  coincides with the location of the central line of a corresponding one of the dicing lines for the singulated imaging device  101 . The blades  431  in such a state are then used to cut the glass sheet  131 , the resin layer  132 , and the sensor section  133  to form grooves  131   g  (see a fourth portion from the top of the left part of  FIG. 11 ). 
     In a fourth step, as illustrated in the fourth portion from the top of the left part of  FIG. 11 , the blades  431  are pulled out, forming grooves  451 , each of which is a combination of the groove  131   f  and the groove  131   g.    
     In a fifth step, as illustrated in a lowermost portion of the left part of  FIG. 11 , the grooves  451  are filled with a black resin  471 . 
     In a sixth step, as illustrated in an uppermost portion of a right part of  FIG. 11 , the blades  421  are positioned such that the location of the central line of each of the blades  421  coincides with a location of a corresponding one of ends of the singulated imaging device  101 . The blades  421  in such a state are then used to form grooves  131   h  (see a second portion from the top of the right part of  FIG. 11 ) having a smaller width and a smaller depth than the grooves  131   f  in the black resin  371 . 
     In a seventh step, as illustrated in the second portion from the top of the right part of  FIG. 11 , blades  491  having a smaller width than the blades  431  are positioned such that a location of a central line of each of the blades  491  coincides with the location of the central line of a corresponding one of the dicing lines for the singulated imaging device  101 . The blades  491  in such a state are then used to cut (dice) the glass sheet  131 , the resin layer  132 , the sensor section  133 , and the dicing sheet  181 . 
     In an eighth step, the blades  491  are pulled out, thereby yielding the singulated imaging device  101  as illustrated in a third portion from the top of the right part of  FIG. 11 . 
     That is, as a result of the singulated imaging device  101  being yielded by cutting the grooves  131   h  along central lines thereof using the blades  491 , opposite end portions of the grooves  131   h  are formed to be the tapered recess  111 ′ in the end portion of the glass sheet  31  of the imaging device  101 . 
     Furthermore, the black resin  471  is left as the grooves  131   h  in the recess  111 ′, thereby forming a constituent element corresponding to the black resin section  411  in  FIG. 10 . 
     Thus, of the glass sheet  31 , a range excluding the recess  111 ′ is formed as the surface F 101  including the film formation region. The surface F 101  has substantially the same shape and substantially the same size as the opening  161  of the tray  151 . To be exact, the surface F 101  is slightly smaller than the opening  161 . 
     In a ninth step, the recess  111 ′ is abutted by the claw  162 ′ with the surface F 101  being the film formation region exposed from the opening  161 ′ as illustrated in  FIG. 10 . The vapor deposition process is performed from below in  FIG. 10 , and thus the AR film  141  being an inorganic film is able to be formed over the entirety of the surface F 101  being the film formation region. 
     Furthermore, the black resin section  411  ( 471 ) that spans the side surfaces of the imaging device  101  is formed on the recess  111 ′ as illustrated in a lowermost portion of the right part of  FIG. 11 . Since the black resin section  411  absorbs incoming light and reflected light entering from the side surfaces, it is possible to reduce occurrence of ghost and flare. 
     6. EXAMPLE OF APPLICATION TO ELECTRONIC APPARATUS» 
     The imaging device  101  in any of  FIGS. 3, 5, 8, and 10  described above is applicable to various electronic apparatuses including, for example, imaging apparatuses such as digital still cameras and digital video cameras, mobile phones having an imaging function, and other apparatuses having an imaging function. 
       FIG. 12  is a block diagram illustrating a configuration example of an imaging apparatus being an electronic apparatus to which the present technology has been applied. 
     An imaging apparatus  501  illustrated in  FIG. 12  includes an optical system  502 , a shutter  503 , a solid-state imaging device  504 , a drive circuit  505 , a signal processing circuit  506 , a monitor  507 , and memory  508 .

     The optical system  502  includes one or more lenses and guides light from a subject (incident light) to the solid-state imaging device  504  to image the light on a light receiving plane of the solid-state imaging device  504 . 
     The shutter  503  is disposed between the optical system  502  and the solid-state imaging device  504 , and controls a light irradiation period and a light blocking period for light to the solid-state imaging device  504  in accordance with control of the drive circuit  1005 . 
     The solid-state imaging device  504  is in a configuration of a package including the above-described solid-state imaging device.

The signal charge accumulated by the solid-state imaging device  504  is transferred in accordance with a drive signal (timing signal) supplied from the drive circuit  505 . 
     The drive circuit  505  outputs drive signals that control the transfer operation of the solid-state imaging device  504  and a shuttering operation of the shutter  503  to drive the solid-state imaging device  504  and the shutter  503 . 
     The signal processing circuit  506  performs various types of signal processing on the signal charge outputted from the solid-state imaging device  504 . An image (image data) obtained through the signal processing by the signal processing circuit  506  is supplied to the monitor  507  to be displayed thereon or supplied to the memory  508  to be stored (recorded) therein. 
     In the imaging apparatus  501  having such a configuration, the use of the imaging device  101  in any of  FIGS. 3, 5, 8, and 10  instead of the optical system  502  and the solid-state imaging device  504  described above enables formation of an inorganic film over the entirety of the film formation region of the glass sheet in the imaging device. Furthermore, the use of the imaging device  101  in any of  FIGS. 8 and 10  enables reduction of ghost and flare. 
     7. USAGE EXAMPLES OF IMAGING DEVICE»

     8. EXAMPLE OF APPLICATION TO ENDOSCOPIC SURGERY SYSTEM» 
     The technology according to the present disclosure (present technology) is applicable to various products. For example, the technology according to the present disclosure may be applied to an endoscopic surgery system. 
       FIG. 14  is a view depicting an example of a schematic configuration of an endoscopic surgery system to which the technology according to an embodiment of the present disclosure (present technology) can be applied. 
     In  FIG. 14 , a state is illustrated in which a surgeon (medical doctor)  11131  is using an endoscopic surgery system  11000  to perform surgery for a patient  11132  on a patient bed  11133 . As depicted, the endoscopic surgery system  11000  includes an endoscope  11100 , other surgical tools  11110  such as a pneumoperitoneum tube  11111  and an energy device  11112 , a supporting arm apparatus  11120  which supports the endoscope  11100  thereon, and a cart  11200  on which various apparatus for endoscopic surgery are mounted. 
     The endoscope  11100  includes a lens barrel  11101  having a region of a predetermined length from a distal end thereof to be inserted into a body cavity of the patient  11132 , and a camera head  11102  connected to a proximal end of the lens barrel  11101 . In the example depicted, the endoscope  11100  is depicted which includes as a rigid endoscope having the lens barrel  11101  of the hard type. However, the endoscope  11100  may otherwise be included as a flexible endoscope having the lens barrel  11101  of the flexible type. 
     The lens barrel  11101  has, at a distal end thereof, an opening in which an objective lens is fitted. A light source apparatus  11203  is connected to the endoscope  11100  such that light generated by the light source apparatus  11203  is introduced to a distal end of the lens barrel  11101  by a light guide extending in the inside of the lens barrel  11101  and is irradiated toward an observation target in a body cavity of the patient  11132  through the objective lens. It is to be noted that the endoscope  11100  may be a forward-viewing endoscope or may be an oblique-viewing endoscope or a side-viewing endoscope. 
     An optical system and an image pickup element are provided in the inside of the camera head  11102  such that reflected light (observation light) from the observation target is condensed on the image pickup element by the optical system. The observation light is photo-electrically converted by the image pickup element to generate an electric signal corresponding to the observation light, namely, an image signal corresponding to an observation image. The image signal is transmitted as RAW data to a CCU  11201 . 
     The CCU  11201  includes a central processing unit (CPU), a graphics processing unit (GPU) or the like and integrally controls operation of the endoscope  11100  and a display apparatus  11202 . Further, the CCU  11201  receives an image signal from the camera head  11102  and performs, for the image signal, various image processes for displaying an image based on the image signal such as, for example, a development process (demosaic process). 
     The display apparatus  11202  displays thereon an image based on an image signal, for which the image processes have been performed by the CCU  11201 , under the control of the CCU  11201 . 
     The light source apparatus  11203  includes a light source such as, for example, a light emitting diode (LED) and supplies irradiation light upon imaging of a surgical region to the endoscope  11100 . 
     An inputting apparatus  11204  is an input interface for the endoscopic surgery system  11000 . A user can perform inputting of various kinds of information or instruction inputting to the endoscopic surgery system  11000  through the inputting apparatus  11204 . For example, the user would input an instruction or a like to change an image pickup condition (type of irradiation light, magnification, focal distance or the like) by the endoscope  11100 . 
     A treatment tool controlling apparatus  11205  controls driving of the energy device  11112  for cautery or incision of a tissue, sealing of a blood vessel or the like. A pneumoperitoneum apparatus  11206  feeds gas into a body cavity of the patient  11132  through the pneumoperitoneum tube  11111  to inflate the body cavity in order to secure the field of view of the endoscope  11100  and secure the working space for the surgeon. A recorder  11207  is an apparatus capable of recording various kinds of information relating to surgery. A printer  11208  is an apparatus capable of printing various kinds of information relating to surgery in various forms such as a text, an image or a graph. 
     It is to be noted that the light source apparatus  11203  which supplies irradiation light when a surgical region is to be imaged to the endoscope  11100  may include a white light source which includes, for example, an LED, a laser light source or a combination of them. Where a white light source includes a combination of red, green, and blue (RGB) laser light sources, since the output intensity and the output timing can be controlled with a high degree of accuracy for each color (each wavelength), adjustment of the white balance of a picked up image can be performed by the light source apparatus  11203 . Further, in this case, if laser beams from the respective RGB laser light sources are irradiated time-divisionally on an observation target and driving of the image pickup elements of the camera head  11102  are controlled in synchronism with the irradiation timings. Then images individually corresponding to the R, G and B colors can be also picked up time-divisionally. According to this method, a color image can be obtained even if color filters are not provided for the image pickup element. 
     Further, the light source apparatus  11203  may be controlled such that the intensity of light to be outputted is changed for each predetermined time. By controlling driving of the image pickup element of the camera head  11102  in synchronism with the timing of the change of the intensity of light to acquire images time-divisionally and synthesizing the images, an image of a high dynamic range free from underexposed blocked up shadows and overexposed highlights can be created. 
     Further, the light source apparatus  11203  may be configured to supply light of a predetermined wavelength band ready for special light observation. In special light observation, for example, by utilizing the wavelength dependency of absorption of light in a body tissue to irradiate light of a narrow band in comparison with irradiation light upon ordinary observation (namely, white light), narrow band observation (narrow band imaging) of imaging a predetermined tissue such as a blood vessel of a superficial portion of the mucous membrane or the like in a high contrast is performed. Alternatively, in special light observation, fluorescent observation for obtaining an image from fluorescent light generated by irradiation of excitation light may be performed. In fluorescent observation, it is possible to perform observation of fluorescent light from a body tissue by irradiating excitation light on the body tissue (autofluorescence observation) or to obtain a fluorescent light image by locally injecting a reagent such as indocyanine green (ICG) into a body tissue and irradiating excitation light corresponding to a fluorescent light wavelength of the reagent upon the body tissue. The light source apparatus  11203  can be configured to supply such narrow-band light and/or excitation light suitable for special light observation as described above. 
       FIG. 15  is a block diagram depicting an example of a functional configuration of the camera head  11102  and the CCU  11201  depicted in  FIG. 14 . 
     The camera head  11102  includes a lens unit  11401 , an image pickup unit  11402 , a driving unit  11403 , a communication unit  11404  and a camera head controlling unit  11405 . The CCU  11201  includes a communication unit  11411 , an image processing unit  11412  and a control unit  11413 . The camera head  11102  and the CCU  11201  are connected for communication to each other by a transmission cable  11400 . 
     The lens unit  11401  is an optical system, provided at a connecting location to the lens barrel  11101 . Observation light taken in from a distal end of the lens barrel  11101  is guided to the camera head  11102  and introduced into the lens unit  11401 . The lens unit  11401  includes a combination of a plurality of lenses including a zoom lens and a focusing lens. 
     The number of image pickup elements which is included by the image pickup unit  11402  may be one (single-plate type) or a plural number (multi-plate type). Where the image pickup unit  11402  is configured as that of the multi-plate type, for example, image signals corresponding to respective R, G and B are generated by the image pickup elements, and the image signals may be synthesized to obtain a color image. The image pickup unit  11402  may also be configured so as to have a pair of image pickup elements for acquiring respective image signals for the right eye and the left eye ready for three dimensional (3D) display. If 3D display is performed, then the depth of a living body tissue in a surgical region can be comprehended more accurately by the surgeon  11131 . It is to be noted that, where the image pickup unit  11402  is configured as that of stereoscopic type, a plurality of systems of lens units  11401  are provided corresponding to the individual image pickup elements. 
     Further, the image pickup unit  11402  may not necessarily be provided on the camera head  11102 . For example, the image pickup unit  11402  may be provided immediately behind the objective lens in the inside of the lens barrel  11101 . 
     The driving unit  11403  includes an actuator and moves the zoom lens and the focusing lens of the lens unit  11401  by a predetermined distance along an optical axis under the control of the camera head controlling unit  11405 . Consequently, the magnification and the focal point of a picked up image by the image pickup unit  11402  can be adjusted suitably. 
     The communication unit  11404  includes a communication apparatus for transmitting and receiving various kinds of information to and from the CCU  11201 . The communication unit  11404  transmits an image signal acquired from the image pickup unit  11402  as RAW data to the CCU  11201  through the transmission cable  11400 . 
     In addition, the communication unit  11404  receives a control signal for controlling driving of the camera head  11102  from the CCU  11201  and supplies the control signal to the camera head controlling unit  11405 . The control signal includes information relating to image pickup conditions such as, for example, information that a frame rate of a picked up image is designated, information that an exposure value upon image picking up is designated and/or information that a magnification and a focal point of a picked up image are designated. 
     It is to be noted that the image pickup conditions such as the frame rate, exposure value, magnification or focal point may be designated by the user or may be set automatically by the control unit  11413  of the CCU  11201  on the basis of an acquired image signal. In the latter case, an auto exposure (AE) function, an auto focus (AF) function and an auto white balance (AWB) function are incorporated in the endoscope  11100 . 
     The camera head controlling unit  11405  controls driving of the camera head  11102  on the basis of a control signal from the CCU  11201  received through the communication unit  11404 . 
     The communication unit  11411  includes a communication apparatus for transmitting and receiving various kinds of information to and from the camera head  11102 . The communication unit  11411  receives an image signal transmitted thereto from the camera head  11102  through the transmission cable  11400 . 
     Further, the communication unit  11411  transmits a control signal for controlling driving of the camera head  11102  to the camera head  11102 . The image signal and the control signal can be transmitted by electrical communication, optical communication or the like. 
     The image processing unit  11412  performs various image processes for an image signal in the form of RAW data transmitted thereto from the camera head  11102 . The control unit  11413  performs various kinds of control relating to image picking up of a surgical region or the like by the endoscope  11100  and display of a picked up image obtained by image picking up of the surgical region or the like. For example, the control unit  11413  creates a control signal for controlling driving of the camera head  11102 . 
     Further, the control unit  11413  controls, on the basis of an image signal for which image processes have been performed by the image processing unit  11412 , the display apparatus  11202  to display a picked up image in which the surgical region or the like is imaged. Thereupon, the control unit  11413  may recognize various objects in the picked up image using various image recognition technologies. For example, the control unit  11413  can recognize a surgical tool such as forceps, a particular living body region, bleeding, mist when the energy device  11112  is used and so forth by detecting the shape, color and so forth of edges of objects included in a picked up image. The control unit  11413  may cause, when it controls the display apparatus  11202  to display a picked up image, various kinds of surgery supporting information to be displayed in an overlapping manner with an image of the surgical region using a result of the recognition. Where surgery supporting information is displayed in an overlapping manner and presented to the surgeon  11131 , the burden on the surgeon  11131  can be reduced and the surgeon  11131  can proceed with the surgery with certainty. 
     The transmission cable  11400  which connects the camera head  11102  and the CCU  11201  to each other is an electric signal cable ready for communication of an electric signal, an optical fiber ready for optical communication or a composite cable ready for both of electrical and optical communications. 
     Here, while, in the example depicted, communication is performed by wired communication using the transmission cable  11400 , the communication between the camera head  11102  and the CCU  11201  may be performed by wireless communication. 
     An example of an endoscopic surgery system to which the technology according to the present disclosure is applicable has been described above. The technology according to the present disclosure is applicable to, for example, the endoscope  11100 , (the image pickup unit  11402  of) the camera head  11102 , (the image processing unit  11412  of) the CCU  11201 , or the like, out of the components described above. Specifically, for example, the imaging device  101  in any of  FIGS. 3, 5, 8, and 10  is applicable to the image pickup unit  10402 . Applying the technology according to the present disclosure to the image pickup unit  10402  enables reliable formation of an inorganic film over the entirety of the film formation region of the glass sheet in the imaging device. Furthermore, apply the imaging device  101  in any of  FIGS. 3, 5, 8, and 10  enables reduction of ghost and flare. 
     Note that although the endoscopic surgery system has been described as an example here, the technology according to the present disclosure may also be applied to, for example, a microscopic surgery system or the like. 
     9. EXAMPLE OF APPLICATION TO MOBILE BODY» 
     The technology according to the present disclosure (present technology) is applicable to various products. For example, the technology according to the present disclosure may be implemented as an apparatus mounted on any type of mobile body such as an automobile, an electric vehicle, a hybrid electric vehicle, a motorcycle, a bicycle, a personal mobility, an airplane, a drone, a vessel, or a robot. 
       FIG. 16  is a block diagram depicting an example of schematic configuration of a vehicle control system as an example of a mobile body control system to which the technology according to an embodiment of the present disclosure can be applied. 
     The vehicle control system  12000  includes a plurality of electronic control units connected to each other via a communication network  12001 . In the example depicted in  FIG. 16 , the vehicle control system  12000  includes a driving system control unit  12010 , a body system control unit  12020 , an outside-vehicle information detecting unit  12030 , an in-vehicle information detecting unit  12040 , and an integrated control unit  12050 . In addition, a microcomputer  12051 , a sound/image output section  12052 , and a vehicle-mounted network interface (I/F)  12053  are illustrated as a functional configuration of the integrated control unit  12050 . 
     The driving system control unit  12010  controls the operation of devices related to the driving system of the vehicle in accordance with various kinds of programs. For example, the driving system control unit  12010  functions as a control device for a driving force generating device for generating the driving force of the vehicle, such as an internal combustion engine, a driving motor, or the like, a driving force transmitting mechanism for transmitting the driving force to wheels, a steering mechanism for adjusting the steering angle of the vehicle, a braking device for generating the braking force of the vehicle, and the like. 
     The body system control unit  12020  controls the operation of various kinds of devices provided to a vehicle body in accordance with various kinds of programs. For example, the body system control unit  12020  functions as a control device for a keyless entry system, a smart key system, a power window device, or various kinds of lamps such as a headlamp, a backup lamp, a brake lamp, a turn signal, a fog lamp, or the like. In this case, radio waves transmitted from a mobile device as an alternative to a key or signals of various kinds of switches can be input to the body system control unit  12020 . The body system control unit  12020  receives these input radio waves or signals, and controls a door lock device, the power window device, the lamps, or the like of the vehicle. 
     The outside-vehicle information detecting unit  12030  detects information about the outside of the vehicle including the vehicle control system  12000 . For example, the outside-vehicle information detecting unit  12030  is connected with an imaging section  12031 . The outside-vehicle information detecting unit  12030  makes the imaging section  12031  image an image of the outside of the vehicle, and receives the imaged image. On the basis of the received image, the outside-vehicle information detecting unit  12030  may perform processing of detecting an object such as a human, a vehicle, an obstacle, a sign, a character on a road surface, or the like, or processing of detecting a distance thereto. 
     The imaging section  12031  is an optical sensor that receives light, and which outputs an electric signal corresponding to a received light amount of the light. The imaging section  12031  can output the electric signal as an image, or can output the electric signal as information about a measured distance. In addition, the light received by the imaging section  12031  may be visible light, or may be invisible light such as infrared rays or the like. 
     The in-vehicle information detecting unit  12040  detects information about the inside of the vehicle. The in-vehicle information detecting unit  12040  is, for example, connected with a driver state detecting section  12041  that detects the state of a driver. The driver state detecting section  12041 , for example, includes a camera that images the driver. On the basis of detection information input from the driver state detecting section  12041 , the in-vehicle information detecting unit  12040  may calculate a degree of fatigue of the driver or a degree of concentration of the driver, or may determine whether the driver is dozing. 
     The microcomputer  12051  can calculate a control target value for the driving force generating device, the steering mechanism, or the braking device on the basis of the information about the inside or outside of the vehicle which information is obtained by the outside-vehicle information detecting unit  12030  or the in-vehicle information detecting unit  12040 , and output a control command to the driving system control unit  12010 . For example, the microcomputer  12051  can perform cooperative control intended to implement functions of an advanced driver assistance system (ADAS) which functions include collision avoidance or shock mitigation for the vehicle, following driving based on a following distance, vehicle speed maintaining driving, a warning of collision of the vehicle, a warning of deviation of the vehicle from a lane, or the like. 
     In addition, the microcomputer  12051  can perform cooperative control intended for automatic driving, which makes the vehicle to travel autonomously without depending on the operation of the driver, or the like, by controlling the driving force generating device, the steering mechanism, the braking device, or the like on the basis of the information about the outside or inside of the vehicle which information is obtained by the outside-vehicle information detecting unit  12030  or the in-vehicle information detecting unit  12040 . 
     In addition, the microcomputer  12051  can output a control command to the body system control unit  12020  on the basis of the information about the outside of the vehicle which information is obtained by the outside-vehicle information detecting unit  12030 . For example, the microcomputer  12051  can perform cooperative control intended to prevent a glare by controlling the headlamp so as to change from a high beam to a low beam, for example, in accordance with the position of a preceding vehicle or an oncoming vehicle detected by the outside-vehicle information detecting unit  12030 . 
     The sound/image output section  12052  transmits an output signal of at least one of a sound and an image to an output device capable of visually or auditorily notifying information to an occupant of the vehicle or the outside of the vehicle. In the example of  FIG. 16 , an audio speaker  12061 , a display section  12062 , and an instrument panel  12063  are illustrated as the output device. The display section  12062  may, for example, include at least one of an on-board display and a head-up display. 
       FIG. 17  is a diagram depicting an example of the installation position of the imaging section  12031 . 
     In  FIG. 17 , the imaging section  12031  includes imaging sections  12101 ,  12102 ,  12103 ,  12104 , and  12105 . 
     The imaging sections  12101 ,  12102 ,  12103 ,  12104 , and  12105  are, for example, disposed at positions on a front nose, sideview mirrors, a rear bumper, and a back door of the vehicle  12100  as well as a position on an upper portion of a windshield within the interior of the vehicle. The imaging section  12101  provided to the front nose and the imaging section  12105  provided to the upper portion of the windshield within the interior of the vehicle obtain mainly an image of the front of the vehicle  12100 . The imaging sections  12102  and  12103  provided to the sideview mirrors obtain mainly an image of the sides of the vehicle  12100 . The imaging section  12104  provided to the rear bumper or the back door obtains mainly an image of the rear of the vehicle  12100 . The imaging section  12105  provided to the upper portion of the windshield within the interior of the vehicle is used mainly to detect a preceding vehicle, a pedestrian, an obstacle, a signal, a traffic sign, a lane, or the like. 
     Incidentally,  FIG. 17  depicts an example of photographing ranges of the imaging sections  12101  to  12104 . An imaging range  12111  represents the imaging range of the imaging section  12101  provided to the front nose. Imaging ranges  12112  and  12113  respectively represent the imaging ranges of the imaging sections  12102  and  12103  provided to the sideview mirrors. An imaging range  12114  represents the imaging range of the imaging section  12104  provided to the rear bumper or the back door. A bird&#39;s-eye image of the vehicle  12100  as viewed from above is obtained by superimposing image data imaged by the imaging sections  12101  to  12104 , for example. 
     At least one of the imaging sections  12101  to  12104  may have a function of obtaining distance information. For example, at least one of the imaging sections  12101  to  12104  may be a stereo camera constituted of a plurality of imaging elements, or may be an imaging element having pixels for phase difference detection. 
     For example, the microcomputer  12051  can determine a distance to each three-dimensional object within the imaging ranges  12111  to  12114  and a temporal change in the distance (relative speed with respect to the vehicle  12100 ) on the basis of the distance information obtained from the imaging sections  12101  to  12104 , and thereby extract, as a preceding vehicle, a nearest three-dimensional object in particular that is present on a traveling path of the vehicle  12100  and which travels in substantially the same direction as the vehicle  12100  at a predetermined speed (for example, equal to or more than 0 km/hour). Further, the microcomputer  12051  can set a following distance to be maintained in front of a preceding vehicle in advance, and perform automatic brake control (including following stop control), automatic acceleration control (including following start control), or the like. It is thus possible to perform cooperative control intended for automatic driving that makes the vehicle travel autonomously without depending on the operation of the driver or the like. 
     For example, the microcomputer  12051  can classify three-dimensional object data on three-dimensional objects into three-dimensional object data of a two-wheeled vehicle, a standard-sized vehicle, a large-sized vehicle, a pedestrian, a utility pole, and other three-dimensional objects on the basis of the distance information obtained from the imaging sections  12101  to  12104 , extract the classified three-dimensional object data, and use the extracted three-dimensional object data for automatic avoidance of an obstacle. For example, the microcomputer  12051  identifies obstacles around the vehicle  12100  as obstacles that the driver of the vehicle  12100  can recognize visually and obstacles that are difficult for the driver of the vehicle  12100  to recognize visually. Then, the microcomputer  12051  determines a collision risk indicating a risk of collision with each obstacle. In a situation in which the collision risk is equal to or higher than a set value and there is thus a possibility of collision, the microcomputer  12051  outputs a warning to the driver via the audio speaker  12061  or the display section  12062 , and performs forced deceleration or avoidance steering via the driving system control unit  12010 . The microcomputer  12051  can thereby assist in driving to avoid collision. 
     At least one of the imaging sections  12101  to  12104  may be an infrared camera that detects infrared rays. The microcomputer  12051  can, for example, recognize a pedestrian by determining whether or not there is a pedestrian in imaged images of the imaging sections  12101  to  12104 . Such recognition of a pedestrian is, for example, performed by a procedure of extracting characteristic points in the imaged images of the imaging sections  12101  to  12104  as infrared cameras and a procedure of determining whether or not it is the pedestrian by performing pattern matching processing on a series of characteristic points representing the contour of the object. When the microcomputer  12051  determines that there is a pedestrian in the imaged images of the imaging sections  12101  to  12104 , and thus recognizes the pedestrian, the sound/image output section  12052  controls the display section  12062  so that a square contour line for emphasis is displayed so as to be superimposed on the recognized pedestrian. The sound/image output section  12052  may also control the display section  12062  so that an icon or the like representing the pedestrian is displayed at a desired position. 
     An example of a vehicle control system to which the technology according to the present disclosure is applicable has been described above. The technology according to the present disclosure is applicable to the imaging section  12031 , for example, among the above-described components. Specifically, for example, the imaging device  101  in any of  FIGS. 3, 5, 8, and 10  is applicable to the imaging section  12031 . Applying the technology according to the present disclosure to the imaging section  12031  enables reliable formation of an inorganic film over the entirety of the film formation region of the glass sheet in the imaging device. Furthermore, applying the imaging device  101  in any of  FIGS. 3, 5, 8, and 10  to the imaging section  12031  enables reduction of ghost and flare.

       FIGS. 18A and 18B  are diagrams illustrating an overview of configuration examples of a stacked solid-state imaging apparatus to which the technique according to the present disclosure is applicable. 
       FIG. 18A  illustrates an example of a schematic configuration of a non-stacked solid-state imaging apparatus. A solid-state imaging apparatus  23010  includes a single die (semiconductor substrate)  23011  as illustrated in  FIG. 18A .

Furthermore, a wiring layer  23101  including a plurality of layers, which in this example is three layers, of wiring lines  23110  is formed in the sensor die  23021 . It should be noted that the control circuit  23013  (Tr that constitutes the control circuit  23013 ) may be included in the logic die  23024  instead of the sensor die  23021 . 
     Tr that constitutes the logic circuit  23014  is formed in the logic die  23024 . Furthermore, a wiring layer  23161  including a plurality of layers, which in this example is three layers, of wiring lines  23170  is formed in the logic die  23024 . A contact hole  23171  having an insulating film  23172  formed on an inner wall surface thereof is formed in the logic die  23024 , and a connection conductor  23173  to be coupled to the wiring lines  23170  and the like is embedded in the contact hole  23171 . 
     The sensor die  23021  and the logic die  23024  are bonded together with their wiring layers  23101  and  23161  facing toward each other, forming the stacked solid-state imaging apparatus  23020  in which the sensor die  23021  and the logic die  23024  are stacked. A film  23191  such as a protective film is formed on a bonding plane between the sensor die  23021  and the logic die  23024 . 
     A contact hole  23111  is formed in the sensor die  23021 . The contact hole  23111  penetrates the sensor die  23021  from a back surface side (side where light enters the PD) (upper side) of the sensor die  23021  and reaches the uppermost layer of wiring line  23170  of the logic die  23024 . Furthermore, a contact hole  23121  is formed in the sensor die  23021 . The contact hole  23121  is located close to the contact hole  23111  and reaches the first layer of wiring line  23110  from the back surface side of the sensor die  23021 . An insulating film  23112  is formed on an inner wall surface of the contact hole  23111 , and an insulating film  23122  is formed on an inner wall surface of the contact hole  23121 . Connection conductors  23113  and  23123  are respectively embedded in the contact holes  23111  and  23121 . The connection conductors  23113  and  23123  are electrically coupled together on the back surface side of the sensor die  23021 , and thus the sensor die  23021  and the logic die  23024  are electrically coupled together via the wiring layer  23101 , the contact hole  23121 , the contact hole  23111 , and the wiring layer  23161 . 
       FIG. 20  is a cross-sectional view illustrating a second configuration example of the stacked solid-state imaging apparatus  23020 . 
     According to the second configuration example of the solid-state imaging apparatus  23020 , a single contact hole  23211  formed in the sensor die  23021  electrically couples the sensor die  23021  (the wiring layer  23101  of the sensor die  23021  (the wiring lines  23110  of the wiring layer  23101 )) and the logic die  23024  (the wiring layer  23161  of the logic die  23024  (the wiring lines  23170  of the wiring layer  23161 )) together. 
     That is, the contact hole  23211  in  FIG. 20  penetrates the sensor die  23021  from the back surface side of the sensor die  23021  and reaches the uppermost layer of wiring line  23170  of the logic die  23024  and also reaches the uppermost layer of wiring line  23110  of the sensor die  23021 . An insulating film  23212  is formed on an inner wall surface of the contact hole  23211 , and a connection conductor  23213  is embedded in the contact hole  23211 . While the sensor die  23021  and the logic die  23024  in  FIG. 19  described above are electrically coupled together by the two contact holes  23111  and  23121 , the sensor die  23021  and the logic die  23024  in  FIG. 20  are electrically coupled together by the single contact hole  23211 . 
       FIG. 21  is a cross-sectional view illustrating a third configuration example of the stacked solid-state imaging apparatus  23020 . 
     The solid-state imaging apparatus  23020  in  FIG. 21  is different from the solid-state imaging apparatus  23020  in  FIG. 19  in that the former does not have the film  23191  such as a protective film formed on the bonding plane between the sensor die  23021  and the logic die  23024  but the latter has the film  23191  such as a protective film formed on the bonding plane between the sensor die  23021  and the logic die  23024 . 
     The solid-state imaging apparatus  23020  in  FIG. 21  is formed by stacking the sensor die  23021  and the logic die  23024  such that the wiring lines  23110  and  23170  are in direct contact with each other, and applying desired load and heat thereto to directly bond the wiring lines  23110  and  23170  together. 
       FIG. 22  is a cross-sectional view illustrating another configuration example of the stacked solid-state imaging apparatus to which the technique according to the present disclosure is applicable. 
     A solid-state imaging apparatus  23401  in  FIG. 22  has a three-layer stacked structure including three stacked dies: a sensor die  23411 , a logic die  23412 , and a memory die  23413 . 
     The memory die  23413  for example includes a memory circuit that performs storage of data temporarily necessary in signal processing being performed in the logic die  23412 . 
     In  FIG. 22 , the logic die  23412  and the memory die  23413  are arranged under the sensor die  23411  into a stack in the stated order, but the logic die  23412  and the memory die  23413  may be arranged under the sensor die  23411  into a stack in the inverse order, which in other words is an order of the memory die  23413  and the logic die  23412 . 
     It should be noted that PD constituting a photoelectric conversion section of each pixel and source/drain regions of each pixel Tr are formed in the sensor die  23411  in  FIG. 22 . 
     A gate electrode is formed around the PD with a gate insulator therebetween, and the gate electrode and the paired source/drain regions form each of a pixel Tr  23421  and a pixel Tr  23422 . 
     The pixel Tr  23421  adjacent to the PD is transfer Tr, and one of the paired source/drain regions forming the pixel Tr  23421  constitutes FD. 
     Furthermore, an inter-layer insulating film is formed in the sensor die  23411 , and contact holes are formed in the inter-layer insulating film. Connection conductors  23431  are formed in the respective contact holes and coupled to the pixel Tr  23421  and the pixel Tr  23422 . 
     Furthermore, a wiring layer  23433  including a plurality of layers of wiring lines  23432  coupled to each of the connection conductors  23431  is formed in the sensor die  23411 . 
     Furthermore, an aluminum pad  23434  that serves as an electrode for external connection is formed in the lowermost layer of the wiring layer  23433  in the sensor die  23411 . That is, the aluminum pad  23434  in the sensor die  23411  is located closer to a bonding plane  23440  between the sensor die  23411  and the logic die  23412  than the wiring lines  23432 . The aluminum pad  23434  is used as one end of a wiring line for input and output of signals to and from the outside. 
     Furthermore, in the sensor die  23411 , a contact  23441  is formed, which is used for electrical coupling of the sensor die  23411  to the logic die  23412 . The contact  23441  is coupled to a contact  23451  in the logic die  23412  and is also coupled to an aluminum pad  23442  in the sensor die  23411 . 
     Furthermore, in the sensor die  23411 , a pad hole  23443  is formed, which reaches the aluminum pad  23442  from a back surface side (upper side) of the sensor die  23411 . 
     The technique according to the present disclosure is applicable to solid-state imaging apparatuses such as described above.
