     DETAILED DESCRIPTION 
       [0020]    Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. 
         [0021]      FIG. 1  is a view illustrating a schematic configuration of a fabrication equipment monitoring device according to an embodiment of the present invention. As illustrated in  FIG. 1 , a fabrication equipment monitoring device  100  includes a mapping server  101  and a plurality of portable terminals  102 . The mapping server  101  and the portable terminal  102  are configured to be capable of communicating with each other. 
         [0022]    As illustrated in  FIG. 2 , the portable terminal  102  includes a communication unit  102   a  configured to communicate with the mapping server  101 . Further, each of the portable terminals  102  includes an image capture element such as a digital camera  102   b , a display and input unit  102   c  configured to display an image captured by the digital camera  102   b  and input the image by, for example, a touch panel, a location information acquisition unit  102   d  configured to acquire a location information about the current location of the portable terminal  102 , a direction detection unit  102   e  configured to detect a direction image-captured by the digital camera  102   b,  and a main control unit  102   f  configured to control the entire portable terminal  102 . 
         [0023]    Further, the portable terminal  102  is adapted to allow the user to manually input and register hazardous site information within the clean room, for example, a site where danger of falling may be caused due to removal of a grating, in the mapping server  101 . For example, a smartphone, a tablet PC, or a wearable computer may be used as the portable terminal  102 . Further, these devices may include a transmissive display device. 
         [0024]    Further, in  FIG. 1 , reference numeral  110  indicates a plurality of semiconductor fabrication devices disposed in the clean room and reference numeral  111  indicates a conveyance system configured to convey, for example, a semiconductor wafer to the semiconductor fabrication devices  110 . For example, an MES (Manufacturing Execution System) or a wafer conveyance mechanism similar to the MES is utilized as the conveyance system  111 . Also, conveyance robot information (e.g., information on a location of a conveyance robot) in the conveyance system  111  is stored in the mapping server  101  at regular time intervals. 
         [0025]    Further, information about each semiconductor fabrication device  110 , for example, the information such as a manufacturing status, an alarm occurrence circumstance, and recipe information are collected by a device data group administration server  112 . Also, data collected by the device data group administration server  112  are stored in the mapping server  101  at regular time intervals. 
         [0026]    The mapping server  101  includes a storage unit  103 . The storage unit  103  stores, for example, an identifier (ID) for specifying the semiconductor fabrication equipment within the clean room, layout information (map information) about the layout of the semiconductor fabrication equipment within the clean room, and various information (semiconductor fabrication equipment information) indicating, for example, a status of the semiconductor fabrication equipment. The semiconductor fabrication equipment information includes, for example, operation situation summary information, operation rate transition information (one day, one week, one month, or one year), conveyance robot location information, an operation manual (e.g., PDF) of, for example, each of the semiconductor fabrication devices. Further, “the semiconductor fabrication equipment” includes the conveyance system  111  and various objects installed within the clean room in addition to the semiconductor fabrication devices  110  which perform various processings on, for example, a semiconductor wafer. 
         [0027]      FIG. 3  is a view illustrates examples of data structures of various information stored in the storage means  103  of the mapping server  101 .  FIG. 3(   a ) illustrates an example of the map information constituting the layout information,  FIG. 3(   b ) illustrates an example of the installed object information,  FIG. 3(   c ) illustrates an example of the device information, and  FIG. 3(   d ) illustrates an example of the conveyance robot information. 
         [0028]    As illustrated in  FIG. 3(   a ), the map information are, for example, a location (X-coordinate and Y-coordinate of a two-dimensional coordinate system and direction), a type-ID of an installed object (a device (model), a stocker, a purpose box, a grating opening, a conveyance robot, an emergency exit, or a passage), an identifier (e.g., a device ID), and a display attribute (presence or absence of an alarm, presence or absence of hazard, or response priority). 
         [0029]    As illustrated in  FIG. 3(   b ), the installed object information are, for example, the type-ID of the installed object (e.g., the device (model), the stocker, the purpose box, the opening in the grating, the conveyance robot, the emergency exit, or the passage), a size (W×H×D), a three dimensional shape (an arbitrary 3D format), and a relevant document (link of an operation manual). 
         [0030]    As illustrated in  FIG. 3(   c ), the device information are, for example, the identifier (device ID), the alarm situation (presence or absence of occurrence of an alarm and details of the alarm), the operation situation (idle, in manufacturing, or stop), a recipe name (a recipe used for a processing), recipe contents (contents of the recipe used for the processing), and an operation rate transition (collected per one day, one week, one month, or one year based on the operation situation). 
         [0031]    As illustrated in  FIG. 3(   d ), the conveyance robot information are, for example, the identifier (conveyance robot ID), the operation situation (in moving or in stopping), a movement source (character string), and a movement destination (character string). 
         [0032]      FIG. 4  is a view illustrates examples of data structures of the portable terminal  102 .  FIG. 4(   a ) illustrates an example of the current location information and  FIG. 4(   b ) illustrates an example of expansion display information. As illustrated in  FIG. 4(   a ), the current location information include, for example, a location (X-coordinate and Y-coordinate of a two-dimensional coordinate system), a direction (e.g., a positive direction in X-axis: 0 degree, a positive direction in Y-axis: 90 degrees, a negative direction in X-axis: 180 degrees, or a negative direction in Y-axis: 270 degrees), and view information (an angle of view (a unique value for each terminal)). 
         [0033]    Further, as illustrated in  FIG. 4(   b ), the expansion display information are, for example, a display location (e.g., (S, T) of a two dimensional coordinate system) of the terminal screen and installed object information (e.g., type-ID of installed object, device ID, and-conveyance robot ID). 
         [0034]    Each portable terminal  102  is constituted by, for example, a smartphone, a tablet PC, or a wearable computer as described above, and includes the display and input unit  102   c  constituted by, for example, an image capture element such as the digital camera  102   b  and the liquid crystal display as illustrated in  FIG. 2 . Also, the portable terminal  102  is adapted to capture an image of the semiconductor fabrication equipment within the clean room by the digital camera  102   b  and display the captured image on the display screen of the display and input unit  102   c.    
         [0035]    Further, the portable terminal  102  includes a location information acquisition unit  102   d  that acquires the location information about the current location of the portable terminal  102  and a direction detection unit  102   e  that detects an image-capturing direction by the digital camera  102   b  (a direction where the digital camera  102   b  is directed). Therefore, for example, as illustrated in  FIG. 5 , when an image of the semiconductor fabrication equipment within the clean room is captured by the digital camera  102   b  and displayed on the display screen of the display and input unit  102   c,  it is possible to obtain information concerning the location and direction where the obtained image has been captured. Further, the location information acquisition function and the direction detection function described above may be implemented by, for example, communicating with a portable base station or a wireless access point and using a sensor such as, for example, a 6-axis sensor (tri-axial geomagnetic sensor and tri-axial acceleration sensor). 
         [0036]    Next, descriptions will be made on monitoring of the semiconductor fabrication equipment by the mapping server  101  and a portable terminal  102  with reference to a flowchart of  FIG. 6 . The worker who performs the monitoring captures an image of the semiconductor fabrication equipment disposed within the clean room using the digital camera of the portable terminal  102  and displays the image on the display device to start a monitoring mode in this state (step  500 ). Further, the image-capturing of the semiconductor fabrication equipment may be performed through, for example, a window at the outside of the clean room. 
         [0037]    First, the portable terminal  102  reads the location and direction of the portable terminal  102  (step  501 ). Next, the portable terminal  102  determines whether there is a change from the previous image-capturing (step  502 ). When it is determined that there is a change, the portable terminal  102  transmits the location information (a location in a XY coordinate system, a direction, and an angle of view) to the mapping server  101  and inquires of the mapping server  101  about the displayed contents (step  503 ). In the meantime, when there is no change, the portable terminal  102  repeats a process which is started from step  501 . 
         [0038]    In the mapping server  101 , the identifier (e.g., device ID) of an installed object displayed on image is specified from the location information (a location in a XY coordinate system, a direction, and an angle of view) transmitted from the portable terminal  102  based on the map information described above, and the information related to the installed object is retrieved (step  511 ). Next, the display coordinates, the display character string and the icon display attributes in the drawing area (an ST coordinate system) for displaying the information about the retrieved installed object are calculated (step  512 ). Also, the calculated information and the information about the presence or absence of (presence or absence of other display information) of the installed object label are transmitted to the portable terminal (step  513 ). 
         [0039]    After receiving the information from the mapping server  101 , the portable terminal  102  performs the drawing processing based on the information such as, for example, the display coordinates, the display character string, or the icon display attributes, and displays the information about the installed object retrieved in the mapping server  101  on the location designated by the display coordinates on the display screen of the portable terminal  102  based on the display character string and the icon display attributes (step  504 ). 
         [0040]    An example of the display screen for the case is illustrated in  FIG. 8 . In the example of the display screen illustrated in  FIG. 8 , for example, the device name (DEVICE A to DEVICE D) labels of the semiconductor fabrication devices are displayed together with the semiconductor fabrication devices displayed on the display screen, for example, by incrementing the device name labels by T sequentially from the nearest object so that the device name labels do not overlap with each other and a part where a portion of the grating is removed to form an opening is displayed as “GRATING OPENING”. Further, since the “GRATING OPENING” becomes the information which represents the hazardous state, it is indicated to be different from the indication of the device name. For example, it is indicated using a color different from the color indicating the device name (e.g., “GRATING OPENING” is indicated by a red color while the device names are indicated by a yellow color). Further, in the example of the display screen illustrated in  FIG. 8 , although a plurality of the semiconductor fabrication devices are illustrated on a single display screen, a worker capture an image of only one semiconductor fabrication device, for example, by standing in front of the one semiconductor fabrication device, and only the captured semiconductor fabrication device information may be displayed on the display screen. 
         [0041]    Next, in the portable terminal  102 , the expansion display information is updated (step  505 ), and then it is determined whether to end the process (step  506 ). When it is determined not to end the process, the process from step  501  is repeated. In the meantime, when it is determined to end the process, the process is ended (step  507 ). 
         [0042]    Further, after the process, as illustrated in  FIG. 7 , when the specific location on the display screen is tapped and the handler on the tap is activated in the portable terminal  102  (step  601 ), the expansion display information is retrieved at the location (S, T) of tap to specify an installed object (step  602 ). 
         [0043]    Then, it is determined whether an installed object label corresponding to the installed object is present or absent (step  603 ), and when it is determined that the installed object label corresponding to the installed object is present, the portable terminal  102  inquires of the mapping server  101  about the displayed contents (step  604 ) and performs the drawing processing based on the information transmitted from the mapping server  101  to display the information (step  605 ). In this case, the displayed contents are, for example, the size the three dimensional shape and the relevant document (e.g., an operation manual) of the installed object. In the case of a semiconductor device, the displayed contents are an alarm situation, an operation situation, a recipe name, recipe contents, an operation rate transition, and in the case of a conveyance robot, the displayed contents are, for example, the operation situation, the movement source, and the movement destination. In the meantime, when there is no corresponding installed object label, the process is ended. 
         [0044]    The portable terminal  102  may have a function that allows each user to select a display mode to customize display (notification) information (e.g., hazardous site information and device information). In this case, for example, the display mode and the display information may be customized as follows. 
         [0045]    Safety inspection mode: notification of alarm in CR and notification of update of hazardous site information (grating opening information) 
         [0046]    Line engineer mode: notification of alarm in CR, notification of update of hazardous site information (grating opening information), notification of process alarm, and notification of maintenance cycle announcement 
         [0047]    FE mode: notification of alarm in CR, notification of update information of hazardous site information (grating opening information), and notification of information process termination announcement 
         [0048]    Operator mode: notification of alarm in CR, and notification of update of hazardous site information (grating opening information) 
         [0049]    When each user selects the display mode to customize the display information (e.g., hazardous site information and device information) as described above, necessary display information may be displayed according to the user. 
         [0050]    Further, the portable terminal  102  may have functions of sending the image information captured by the digital camera  102   b,  and the location information and the direction information about the captured location to the mapping server  101 , and updating various information stored in the storage means  103  in order to share the information. 
         [0051]    For example, in a case where a new “grating opening” for which the information is absent in the mapping server  101  occurs, since this information is the information which indicates hazard (hazardous site information), it is preferable that the information is shared between persons who enter the clean room. In this case, the image of the “grating opening” is captured by the digital camera  102   b  of the portable terminal  102 . The captured image information, the location information and the direction information are sent to the mapping server  101 . In this case, the image information within the portable terminal  102  may be automatically cleared for security so as to prevent the image information from being taken out to the outside. 
         [0052]    The mapping server  101  updates the map information and the information about the “grating opening” of the installed object information from the image information, the location information, and the direction information sent from the portable terminal  102 . Also, the mapping server  101  transmits the updated information to each portable terminal  102  and the updated information is displayed on each portable terminal  102 . 
         [0053]    In this manner, in the case where the “grating opening” for which the information is absent in the mapping server  101  exists, the information about the “grating opening” may be shared between users who carry the portable terminals, respectively. 
         [0054]    Further, in a case where no network is available within the clean room, the portable terminal  102  may be put closer to an NFC tag disposed near to an exit when leaving the clean room to activate an application software of the portable terminal  102  using communication with the NFC tag as a trigger so that the captured image information, the location information, and the direction information may be sent to the mapping server  101  and the image information within the portable terminal  102  may be cleared. Also, in this case, the mapping server  101  updates the map information and the information about the “grating opening” of the installed object information from the image information and the location information sent from the portable terminal  102 . Then, the mapping server  101  transmits the updated information to each portable terminal  102  to be displayed on the portable terminal  102   
         [0055]    Further, the portable terminal  102  may obtain the location information in the following manner. That is, a worker downloads the map information (connecting data of identifier (ID) of the semiconductor fabrication equipment and the location information) into the portable terminal  102  when entering the clean room. 
         [0056]    Then, the worker enters the clean room and stands in front of the semiconductor fabrication equipment (a semiconductor fabrication device  110 ) to obtain the identifier (ID) information thereof. The identifier (ID) information may be obtained by, for example, any one of the following methods. 
         [0057]    A method of obtaining the identifier (ID) information by lighting a signal tower of a semiconductor fabrication device  110  with a specific pattern or color, and recognizing the lighting by the digital camera  102   b  of the portable terminal  102 . 
         [0058]    A method of obtaining the identifier (ID) information by displaying a QR code on the screen of the semiconductor fabrication device  110 , and recognizing the QR code by the digital camera  102   b  of the portable terminal  102 . 
         [0059]    A method of obtaining the identifier (ID) information by attaching an NFC tag stored with the identifier (ID) information of the semiconductor fabrication device  110  to the semiconductor fabrication device  110 , and putting the portable terminal  102  closer to the NFC tag. 
         [0060]    A method of obtaining the identifier (ID) by causing a specific buzzer to sound from the semiconductor fabrication device  110 , and recognizing the sound by a microphone of the portable terminal  102  to calculate the identifier (ID) information from the type of the buzzer 
         [0061]    A method of obtaining the identifier (ID) information by capturing an image of a top screen of the semiconductor fabrication device  110  by the digital camera  102   b  of the portable terminal  102 , and comparing the device state (e.g., an alarm and an execution recipe name) with the information of the device data group administration server  112 . 
         [0062]    Also, with the portable terminal  102 , the current location is grasped from the map information (the connecting data of the identifier (ID) and the location information) downloaded when entering the clean room and the identifier (ID) information of the semiconductor fabrication device  110 . Further, upon having moved from the location, the current location is predicted based on the value of, for example, the above-mentioned 6-axis sensor (tri-axial geomagnetic sensor and tri-axial acceleration sensor). 
         [0063]    Further, in a state where the NFC tag is attached to the specific point within the clean room in advance, the map information (connecting data of a specific point and the location information) is downloaded on the portable terminal  102  when entering the clean room. Upon having entered the clean room, the portable terminal  102  is put closer to the NFC tag at the specific point to grasp the current location. Also, in this case, upon having moved therefrom, the current location is predicted based on the value of, for example, the above-mentioned 6-axis sensor (tri-axial geomagnetic sensor and tri-axial acceleration sensor). 
         [0064]    Further, there is generally a limitation in using a network or portable terminal in the clean room in terms of security. Therefore, the fabrication equipment monitoring device  100  may have a function that inquires of whether the portable terminal  102  is allowed to be carried in the clean room when the worker has the portable terminal and enters the clean room. 
         [0065]    In this case, the portable terminal  102  is put closer to the NFC tag for authorization when entering the clean room. An authentication function within the portable terminal  102  is activated using communication with the NFC tag as a trigger so that when “permission OK information” is present within the portable terminal  102 , the portable terminal  102  is allowed to use the application software and shifts to a use mode within the clean room. In this case, for example, Bluetooth is turned OFF, 3G is turned OFF, and GPS is turned OFF. 
         [0066]    Further, when the “permission OK information” is absent within the portable terminal  102 , for example, the MAC address of the portable terminal  102  is ascertained, for example, by inquiring of the device data group administration server  112  about the MAC address of the portable terminal  102 . When the portable terminal  102  is not allowed to be carried into the clean room, the application software of the portable terminal  102  is made to be unavailable (invalidation of device function) and, for example, the camera function is invalidated, Bluetooth is turned OFF, 3G is turned OFF, GPS is turned OFF. 
         [0067]    Further, the portable terminal  102  has a function that when a specific semiconductor fabrication device  110  is image-captured by the digital camera  102   b , the display of the portable terminal  102  is able to show a status inside of the device as an image similarly to an opened window of the semiconductor fabrication device  110 . This may be implemented by combining the image captured by the portable terminal  102  and the image captured by the camera disposed within the semiconductor fabrication device  110  and displaying the combined image on the display of the portable terminal  102 . 
         [0068]    This function is activated by tapping, for example, the image of the semiconductor fabrication device  110  displayed on the display of the portable terminal  102 , and the image of the panned camera disposed within the semiconductor fabrication device  110  may be displayed by panning (circulating the direction) the portable terminal  102 . In this way, it is possible to ascertain a shape inside the device without opening a maintenance door. 
         [0069]    Further, the portable terminal  102  has a function of displaying a state at the rear side of the semiconductor fabrication device  110  in a state where the semiconductor fabrication device  110  is absent when the specific semiconductor fabrication device  110  is image-captured by the digital camera  102   b.  That is, when an image of a camera disposed behind the semiconductor fabrication device  110  is subjected to a projection mapping to be superposed on the surface of the semiconductor fabrication device  110  in the AR space, an image of a state where the semiconductor fabrication device  110  is absent is displayed. This function is activated by tapping, for example, the image of the semiconductor fabrication device  110  displayed on the display of the portable terminal  102 . In this manner, it is possible to perform a safety confirmation of the rear side of the semiconductor fabrication device  110  which becomes a blind spot. 
         [0070]    As described above, according to the present embodiment, when a semiconductor fabrication equipment such as a semiconductor fabrication device  110  is image-captured by a digital camera  102   b  of a portable terminal  102 , the information, such as, for example, the device name, the device state, the device operation manual of the semiconductor fabrication device  110  may be displayed to overlap with the captured image. Further, the hazardous site information of, for example, a grating opening where, for example, a worker is in danger of falling. Therefore, the larger amount of information about the semiconductor fabrication equipment may be easily acquired compared to the related art. 
         [0071]    Further, the present invention is not limited to the embodiment described above and various modifications may also be made thereto.
