A light transmissive member is charged between a glass interposer and a CMOS image sensor (CIS). Since rigidity of the glass interposer can be enhanced by this configuration, it is possible to suppress deflection of the CIS and also reduce influence of distortion given to a gyro sensor and the like which are equipped on the glass interposer, and therefore, erroneous detection of a gyro signal can be reduced.

SUMMARY OF THE INVENTION

Problems to be Solved by the Invention

However, according to a technology disclosed in Patent Document 1, in a case where a gyro sensor used to correct blurring caused by camera shake is mounted together with an image sensor on a glass substrate, warpage may be caused during a manufacturing process and during use because a linear expansion coefficient of the glass substrate differs from silicon used in the image sensor and gyro sensor, thereby also causing distortion in the mounted gyro sensor. The distortion may generate an erroneous gyro signal, and there is a possibility that blurring caused by camera shake cannot be corrected.

Additionally, in a technology disclosed in Patent Document 2, a chip (a memory chip, a logic chip, or a complementary metal oxide semiconductor (CMOS) image sensor (CIS)) chip, a micro electro mechanical systems (MEMS) chip, or the like) is provided on a light receiving surface of a glass substrate and is connected to a substrate on a back side of the glass substrate with a through electrode. Therefore, since the light receiving surface is exposed without contacting the glass substrate, a protective glass substrate or the like is separately needed, and there is a possibility that height reduction cannot be achieved when modularized.

The present disclosure is made in view of the above-described situations, and in a case where a gyro sensor is mounted together with an image sensor on a glass substrate, the present invention is directed to achieving: reduction of distortion caused by a difference in a linear expansion coefficient between the glass substrate and silicon used in the gyro sensor and image sensor; and height reduction by having a configuration in which a light receiving surface of an equipped chip contacts the glass substrate.

MODE FOR CARRYING OUT THE INVENTION

In the following, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Note that, in the present specification and the drawings, a constituent element having substantially a same functional configuration will be denoted by a same reference sign and repetition of the same description will be omitted.

Additionally, note that the description will be provided in the following order.

1. Embodiments in Related art

2. First Embodiment

3. Second Embodiment

1. Embodiments in Related Art

FIGS. 1 and 2are exemplary configurations of camera modules each including a glass interposer module according first and second embodiments in the related art corresponding to Patent Documents 1 and 2.

InFIG. 1, light is incident downward from an upper side of the drawing. An image sensor D is connected to a lower side of a transparent substrate (glass substrate) A in the drawing via a sealing ring C and a solder bump F. The image sensor D is provided such that a light receiving surface E faces an incident direction of incident light. Additionally, a semiconductor chip element (LCR) B is equipped at a lower portion of the transparent substrate A in the drawing and next to the image sensor D.

With this configuration, the light receiving surface E can be protected by the transparent substrate A, and thermal stress at the time of bonding can be reduced.

However, in a case of having the configuration ofFIG. 1, warpage may be caused by a difference in a thermal expansion coefficient between the transparent substrate A and the image sensor D, and for example, in a case where the semiconductor chip element B is not the LCR but a gyro sensor or the like, erroneous detection may be caused in a gyro signal of the gyro sensor and there is a possibility that a proper gyro signal cannot be output.

Accordingly, as illustrated inFIG. 2, proposed in the Patent Document 2 is a configuration in which a plurality of electronic components having terminals on a surface of a transparent substrate (glass substrate) P is stacked interposing a resin layer N while an upper side of a semiconductor chip element L in the drawing is set as a light receiving surface M, and a plurality of layers including a terminal, a solder layer, and a terminal is stacked and connected by performing heating and load application at the same time without solder bonding, and then the plurality of electronic components (between terminals) is solder-bonded at a time, thereby suppressing occurrence of resin biting (that is a state in which a resin enters a space between the terminals, and the connected state between the terminal, solder layer, and terminal is eliminated).

However, in the case of such a configuration, the light receiving surface M of the semiconductor chip element L is not connected to the transparent substrate P, and therefore, a protective transparent layer is separately needed, and consequently, there is a possibility that height reduction cannot be achieved when modularized.

2. First Embodiment

Next, a camera module to which the glass interposer module of the present disclosure is applied will be described with reference toFIG. 3. Note that an upper portion ofFIG. 3is a top view of the camera module, and a lower portion ofFIG. 3is a cross section of a left portion of the camera module taken along line AA inFIG. 3.

A camera module11includes a glass interposer (IP)31as a whole. The glass IP31is provided with an insulation layer55having an opening at a center of a back surface thereof.

The insulation layer55is provided with wiring layers54-1and54-2respectively on an upper surface portion and a lower surface portion thereof inFIG. 3, and the wiring layer54-2out of these wiring layers is electrically connected to a CMOS image sensor (CIS)41provided at the center of the back surface via a bump52.

The bump52includes gold (Au) or the like and bonded by Au bump bonding with ultrasonic waves, for example. Incidentally, the bump52may be an Au bump, a solder bump, a Cu core bump, or a combination thereof.

The CIS41has an upper surface portion provided with a color filter42, and light corresponding to each of wavelengths of R, G, and B is transmitted per pixel in a Bayer array, for example.

The glass IP31has an upper surface pasted or applied with an IR cut filter53that shields only light having a wavelength corresponding to infrared light.

Additionally, the glass IP31has a side surface portion provided with a light absorbing member56that suppresses incidence of stray light by absorbing light incident from a side surface direction.

A light transmissive member51is charged between the glass IP31and the CIS41(having the color filter42provided on the upper surface thereof).

The glass IP31includes alkali-free glass or the like, and has a linear expansion coefficient similar to that of silicon. For example, a material having a linear expansion coefficient of 0.7 to 6×10−6(K−1) can be used for a linear expansion coefficient of 1 to 4.5×10−6(K−1) of silicon, but it is preferable that the linear expansion coefficient be close to that of silicon at a use temperature.

As for the light transmissive member51, a material having a Young's modulus of 0.1 to 10 GPa can be used, but having the Young's modulus of 1 GPa or more is preferable because warpage of the CIS41can be suppressed, and a material quality not containing a halogen element is to be used.

The glass IP31and the light transmissive member51each can have an Abbe number of 40 or more, but the Abbe number of 55 or more is preferable because color dispersion can be reduced.

Alternatively, even in a case where the light transmissive member51has the Abbe number of 25 or more, color dispersion can be reduced by using a material having an Abbe number of 40 or more for the glass IP31in accordance with an achromatization condition.

Furthermore, the glass IP31and the light transmissive member51each can have transmissivity of 90% or more, preferably, 95% or more.

The light absorbing member56is an antireflection member including a multilayer film in which a refractive index (material) and a film thickness are controlled.

Since the light transmission member51is thus charged between the glass IP31and the CIS41, entire rigidity can be enhanced, deformation is hardly caused by external force, and flatness of the CIS41can be maintained.

Additionally, even in a case where warpage stress of the CIS41is caused by a difference in a linear expansion coefficient from the glass IP31, flatness of the CIS can be maintained because of support by the charged light transmission member51.

3. Second Embodiment

In the above, described is an example in which a camera module11is formed as a single body of a glass IP31, but that camera module may also have a configuration including a flexible printed circuit (FPC) and a physical sensor.

FIG. 4illustrates an exemplary configuration of the camera module11including, in the glass IP, an FPC and a physical sensor. Note that a component having a function same as a component of a camera module11inFIG. 3is denoted by a same reference sign and a same name, and a description therefor will be suitably omitted, and the same shall be applied in the following.

In the example ofFIG. 4, a gyro sensor43, a driving driver44including an auto focus (AF) mechanism, an optical image stabilizer (OIS), and the like, and a heat dissipation pad45are physically and electrically bonded to a wiring layer54-2of a glass IP31via a bump52. The bump52is connected by Au bump connection with ultrasonic waves.

Incidentally, the gyro sensor43, driving driver44including an auto focus (AF) mechanism, an optical image stabilizer (OIS), or the like, and heat dissipation pad45may be physical sensors or control components other than these, and for example, an acceleration sensor, a geomagnetic sensor, a hall element sensor, or the like may be applicable.

A material having a linear expansion coefficient in a range of 0.7 to 6×10−6(K−1) can be used for the gyro sensor43, driving driver44including an auto focus (AF) mechanism, an optical image stabilizer (OIS), and the like, and heat dissipation pad45, but it is preferable that the linear expansion coefficient be closer to a linear expansion coefficient of silicon at a use temperature.

As illustrated inFIG. 4, an FPC32is bonded to a wiring surface54-2located at a plate end of the glass IP31by, for example, an anisotropic conductive film57at a position interposing the CIS41and facing the gyro sensor43, driving driver44including an auto focus (AF) mechanism, an optical image stabilizer (OIS), and the like, and heat dissipation pad45while interposing an image sensor41.

Since entire rigidity is thus increased by charging a light transmissive member51between the glass IP31and the CIS41and deformation is hardly caused by external force, and the gyro sensor43is mounted on the glass IP31in which flatness is maintained, occurrence of erroneous detection such as offset of a signal can be suppressed.

Additionally, heat dissipation efficiency can be improved by the waste heat pad45.

In the above, described is an example of a camera module11in which rigidity is enhanced by charging a light transmissive member51between a glass IP31and a CIS41, but a glass wafer level lens may also be included.

FIG. 5illustrates an exemplary configuration of the camera module11including a glass wafer level lens.

The glass wafer level lens71is stacked on a surface of the glass IP31located on an opposite side of a surface provided with a wiring layer54-1. A center portion of the glass wafer level lens71includes a circular projecting portion71a.

A light transmissive member72similar to a light transmissive member51is charged between the glass wafer level lens71and an IR cut filter53located on an upper surface of the glass IP31.

The glass wafer level lens71has ranges of a linear expansion coefficient, a Young's modulus, an Abbe number, and transmissivity similar to those of the glass IP31and light transmissive member51.

Since rigidity can be further enhanced by thus bonding of the glass wafer level lens71, deflection of the glass IP31caused by external force can be further suppressed, and it is possible to further suppress erroneous detection such as offset of a signal of the gyro sensor43.

In the above, described is an example of a camera module11in which rigidity is enhanced by charging a light transmissive member51between a glass IP31and a CIS41, but rigidity may also be enhanced by further providing a through glass via (TGV) and forming or charging a conductive member on or to an inner wall thereof.

FIG. 6illustrates an exemplary configuration of a camera module11in which a through glass via (TGV) is provided in a glass IP and a conductive member is formed on and charged to an inner wall thereof.

The glass IP31of the camera module11inFIG. 6is provided with the through glass via (TGV), and a TGV attached with a conductive member91having a conductive member formed on or charged to the inner wall thereof is provided.

As illustrated in an upper portion ofFIG. 6, TGVs each attached with a conductive member91are arranged at equal intervals or unequal intervals in a manner surrounding a light receiving surface of a CIS41, and are arrayed in a plurality of columns.

Additionally, a metal such as copper (Cu) or aluminum (Al) but also polysilicon and the like are charged into conductive member TGV91.

With this configuration, rigidity of the glass IP31can be enhanced and also a degree of freedom in wiring layout can be increased. As a result, a gyro sensor43and an FPC32can be connected to not only to a back surface of the glass IP31but also to an upper surface side thereof in the drawing.

In the above, described is an example of a camera module11in which rigidity is enhanced by charging a light transmissive member51between a glass IP31and a CIS41, but rigidity may also be enhanced by further providing a through glass via (TGV) and charging a light absorbing member thereto.

FIG. 7illustrates an exemplary configuration of a camera module11in which a TGV is provided in a glass IP31and a light absorbing member is charged thereto.

In the camera module11ofFIG. 7, the TGV is provided in the glass IP31, and a TGV attached with a light absorbing member111charged with a light absorbing member is provided.

The TGV attached with a light absorbing member111is an antireflection member including a multilayer film in which a refractive index (material) and a film thickness are controlled, and is charged into a TGV under vacuum.

As illustrated in an upper portion ofFIG. 7, TGVs each attached with a light absorbing member111are arranged in a plurality of columns (for example, three columns) at equal intervals or unequal intervals in a manner surrounding a light receiving surface of a CIS41.

With this configuration, rigidity of the glass IP31can be enhanced and also stray light inside the glass IP31can be suppressed by the TGVs each attached with a light absorbing member111.

In the above, described is an example in which a TGV attached with a conductive member or a TGV attached with a light absorbing member is provided in a camera module11having rigidity enhanced by charging a light transmissive member51between a glass IP31and a CIS41, but both TGVs may also be provided.

FIG. 8illustrates an exemplary configuration of a camera module11in which both of a TGV attached with a conductive member91and a TGV attached with a light absorbing member111are formed in a glass IP31.

In the camera module11ofFIG. 8, a TGV attached with a conductive member91and a TGV attached with a light absorbing member111are formed in a glass IP31, and as illustrated in an upper portion ofFIG. 8, the respective kinds of TGVs are arranged in a plurality of columns (for example, three columns) at equal intervals or unequal intervals in a manner surrounding a light receiving surface of a CIS41, and the TGVs each attached with a light absorbing member111is arranged on a more inner side than the TGVs each attached with a conductive member91are arranged.

With this configuration, rigidity of the glass IP31is further enhanced, a degree of freedom in wiring layout can be increased the TGVs each attached with a conductive member91, and also stray light inside the glass IP31can be suppressed by the TGVs each attached with a light absorbing member111.

In the above, described is an example of a camera module11in which rigidity is enhanced by charging a light transmissive member51between a glass IP31and a CIS41, but it may be possible to be apply a stereo type camera module including a plurality of light receiving surfaces.

FIG. 9illustrates an exemplary configuration of a stereo type camera module11.

In the camera module11ofFIG. 9, a CIS141of a stereo camera type is provided instead of a CIS41in a camera module ofFIG. 3. Light receiving surfaces corresponding to a right eye and a left eye respectively are set, and color filters42-1and42-2are provided respectively.

However, basic configurations of the CIS41and the CIS141are the same except that the CIS141has the plurality of light receiving surfaces.

In other words, light transmissive members51-1,51-2are charged between the glass IP31and each of the color filters42-1,42-2of the CIS141, respectively. Therefore, rigidity of the glass IP31provided with the CIS141is enhanced, and flatness of the CIS141can be maintained even in a case warpage stress of the CIS141is caused by a difference in a linear expansion coefficient from that of the glass IP31, and furthermore, erroneous detection in a gyro sensor43can be suppressed.

Additionally, since the plurality of light receiving surfaces is provided, a deviation in an optical axis between left and right sides can be suppressed more than in a case where a CIS41is individually mounted. As a result, for example, imaging can be performed with high accuracy even at the time of capturing a depth image with a stereo camera.

Meanwhile, a conductive member TGV91and a TGV attached with a light absorbing member111may also be formed in the glass IP31of the camera module11inFIG. 9, and similar effects can be obtained.

Additionally, with this configuration, for example, the camera module is equipped on a vehicle and can also be used with high accuracy as a stereo camera to image a distance to an obstacle in front during travel, a preceding vehicle in following traveling, and the like.

Furthermore, in the above, the example of having the two light receiving surfaces is described, but more than two light receiving surfaces may be provided.

In the above, described is an example of a camera module11in which rigidity is enhanced by charging a light transmissive member51between a glass IP31and a CIS41, but a redistribution layer (RDL) may be further provided by applying a coating resin (fan-out resin) to a back surface of the CIS41.

FIG. 10illustrates an exemplary configuration of a camera module11in which a redistribution layer (RDL) is provided by applying a coating resin (fan-out resin) to a back surface of a CIS41.

In the camera module11illustrated inFIG. 10, a coating resin wiring (fan-out resin wiring)131is formed on the back surface of the CIS41by applying the coating resin, and a redistribution layer (RDL)132is further provided and electrically connected to a wiring layer54-2.

With this configuration, rigidity of a glass IP31is enhanced and also the number of input/output terminals can be increased by the coating resin wiring131.

In the above, described is an example of a camera module11in which rigidity is enhanced by charging a light transmissive member51between a glass IP31and a CIS41, but a TGV attached with a conductive member, a TGV attached with a light absorbing member, or a cavity may be further provided in a region of the glass IP31where a gyro sensor43is connected.

FIG. 11illustrates an exemplary configuration of a camera module11in which a TGV attached with a conductive member, a TGV attached with a light absorbing member, or a cavity is provided in a region of the glass IP31connected to the gyro sensor43.

In the camera module11ofFIG. 11, a TGV151and a cavity152are formed in the glass IP31, and each of TGV151and a cavity152includes any one of a TGV attached with a conductive member and a TGV attached with a light absorbing member or combination both thereof.

The TGV151and cavity152are arranged locally, particularly, immediately below or around the gyro sensor43.

Meanwhile, the cavity152may have an inner wall including a light absorbing member or a conductive member, or may be charged with a light absorbing member or a conductive member.

With this configuration, even in a case where a linear expansion coefficient of the glass IP31is in a predetermined range, thermal stress deformation caused by a difference from silicon can be suppressed to a little deformation amount by controlling rigidity of the glass IP31in the vicinity of the gyro sensor43by the TGV151and cavity.152. As a result, erroneous detection such as offset of a gyro signal of the gyro sensor43can be suppressed.

Additionally, in a case where a light absorbing member is used, stray light inside the glass IP31can be suppressed.

<Exemplary Application to Electronic Apparatus>

A camera module11using a CIS41or a CIS141described above can be applied to various kinds of electronic apparatuses such as imaging devices such as a digital still camera and a digital video camera (digital camera), a mobile phone (portable information terminal) having an imaging function, or another apparatus having an imaging function (for example, an in-vehicle camera and the like), for example.

The optical system202includes one or a plurality of lenses, and guides light (incident light) from a subject to the solid-state imaging element204, and forms an image on a light receiving surface of the solid-state imaging element204.

The solid-state imaging element204includes a package including the above-described solid-state imaging element. The solid-state imaging element204accumulates signal charge for a predetermined period in accordance with light from which an image is formed on the light receiving surface via the optical system202and shutter device203. The signal charge accumulated in the solid-state imaging element204is transferred in accordance with a drive signal (timing signal) supplied from the drive circuit205.

The drive circuit205outputs a drive signal to control transfer operation of the solid-state imaging element204and shutter operation of the shutter device203, and drives the solid-state imaging element204and shutter device203.

The signal processing circuit206applies various kinds of signal processing to signal charge output from the solid-state imaging element204. An image (image data) obtained by applying the signal processing by the signal processing circuit206is supplied and displayed on the monitor207, or supplied and stored (recorded) in the memory208.

In the imaging device201thus configured, distortion of a glass IP31can be also suppressed by applying a camera module using a CIS41or a CIS141in place of the above-described solid-state imaging element204, and even in a case of mounting a gyro sensor together and the like therewith, erroneous detection of a gyro signal can be reduced.
