Hereinafter, Embodiment 1 of the production management system and the production management method of the present invention will be described in detail with reference to the drawings. Note that the size of each configuration in each figure is not limited to the illustrated configuration from the viewpoint of drawing creation.

(Embodiment 1)
FIG. 1A is a perspective view showing a state of a tray on which lot wafers are placed and a plurality of stacked wafers in the production management system according to the first embodiment of the present invention, and FIG. FIG. 6 is a perspective view for explaining a rule for managing the wafer location on the tray of FIG.

In FIG. 1A, when the wafer size is reduced to several inches, it is often transported and stored in units of one or a plurality of trays 81. On the tray 81, a plurality of (here, nine sheets) wafers 82 as samples (lots) are mounted and used. On the surface of the tray 81, nine recesses slightly larger than the diameter of the wafers 82 are formed in a matrix in the vertical direction and the horizontal direction, and the wafers 82 are respectively accommodated in the recesses. An RFID chip 83 (RFID tag) is fixed to the side surface of the tray 81. In the RFID chip 83, information such as an ID number is registered for each tray 81. A plurality of trays 81 on which wafers 82 are placed are transported as a group of trays 81A, stacked in the vertical direction and stored in the sample shelf.

In short, when the existing device manufacturing line is an environment of an old generation, for example, when the flow wafer has a small inch size, the flow unit or the transport means may be operated by the tray 81 instead of the cassette. In the case of flow by the tray 81, since the efficiency of the conveyance by the individual trays 81 is low, a plurality of trays 81 may be stacked in advance and conveyed as a tray group 81A.

In that case, not only the management unit of the conventional shelf management system is changed, but also a set of gate-type RFID sensors (gates to be described later) from the method of managing the location by installing an RFID reader for each cassette. By laying the type RFID reader 10a), it is possible to monitor the location of the tray 81 by an event of the tray 81 being taken in and out of the shelf.

As shown in FIG. 1B, the location management rule for a plurality of wafers 82 on the tray 81 will be described. For example, the position of the wafer 82 on the tray 81 is set to No. 1 to 3 and No. 2 in the second line. 4-6, No. 3 in the third line. Here, the positions of all nine wafers 82 are determined as 7-9. Of course, the positions of the plurality of wafers 82 may be determined not in the horizontal row direction but in the vertical column direction.

FIG. 2 is a perspective view of a sample shelf used in the sample management shelf system in the production management system of Embodiment 1, and FIG. 2 (a) is a perspective view of the sample shelf for explaining the tray ID reader means. FIG. 2B is a perspective view of the sample shelf showing a state in which a plurality of trays on which wafers are placed are stacked on the sample shelf.

2 (a) and 2 (b), one tray 81 carrying a plurality of wafers 82 is taken as one lot, and a plurality of trays are stacked to form a tray group 81A of a plurality of lots as a single tray unit for transporting a sample. It is stored and managed on the shelf 10.

The sample shelf 10 has a gate type RFID reader 10a as a tray ID reader means. Two sensor main pillars of the gate type RFID reader 10a are erected on both sides of the front surface of the sample shelf 10 to cover the sensing of the tray group 81A, which is a plurality of trays 81 passing through the front surface of the sample shelf 10. Yes. In short, even a plurality of trays 81 can be collectively detected as a tray group 81A by a single sensing instead of a plurality of sensings. The gate type RFID reader 10a detects the new appearance on the shelf and the disappearance from the shelf by the passage of the tray group 81A, and detects the number of the trays 81 in the entire shelf. The gate type RFID reader 10a can collectively detect the data (tray number) in the RFID chip 83 and the total quantity of each tray 81.

If the fluid wafer size is reduced to a few inches, the number of fluid wafers will increase accordingly, and the inventory quantity will also increase in units of trays. By attaching a gate type RFID reader 10a rather than laying an RFID reader for each cassette (lot), which will be described later, it is possible to manage the location of trays for loading and unloading with a lump stacked on a plurality of trays 81, and inventory in real time. It is possible to perform tray location management as to which sample shelf 10 has the tray group 81A.

In short, in a production process with a small wafer size, conveyance by the tray 81 is generally performed, and stacking is realized by realizing ID location management of the tray 81 by the RFID chip 83 for each tray 81 using the gate type RFID reader 10a. The location management of the tray 81 or the tray group 81A can be automatically realized in real time by passing the entry / exit event of the tray group 81A, which is a plurality of trays 81, through the gate-type RIFD reader 10a. Further, as a production management system, by tracing the position of the wafer 82 on the tray 81 as well, individual piece tracing of the wafer 82 can be realized.

FIG. 3 is a schematic diagram showing an outline of work in the manual conveyance process using the tray 81 in the first embodiment of the sample management shelf system in the production management system of the present invention.

In FIG. 3, in the sample management shelf system 11 in the production management system of the first embodiment, one or a plurality of trays 81 (lots) processed by each processing apparatus have passed through the gate type RFID reader 12a as a tray ID reader means. Whether or not one or a plurality of trays 81 is detected and stored, and a navigation screen 13a for the one or a plurality of trays 81 detected by the gate type RFID reader 12a of the sample shelf 12 before processing. In the case of the pre-processing sample shelf management personal computer 13 for performing the next processing instruction and one or a plurality of trays 81 taken out from the pre-processing sample shelf 12 and transported to the processing apparatus, and the wafer 82 on the tray 81 is set in the processing apparatus. And the transfer time when the processed wafer 82 is taken out onto the tray 81, etc. An apparatus management personal computer 14 that gives instructions to the operator on the navigation screen 14a, and a wafer 82 that has been processed by the processing apparatus is taken out from the processing apparatus onto the tray 81 and conveyed to one or more trays 81 ( A processed sample shelf 15 that detects the presence or absence of one or a plurality of trays 81 depending on whether or not a lot has passed through the gate-type RFID reader 15 a and one detected by the gate-type RFID reader 15 a of the processed sample shelf 15. Alternatively, the processed sample shelf management personal computer 16 that instructs the plurality of trays 81 to carry the next process on the navigation screen 16a, the pre-process sample shelf management personal computer 13, the device management personal computer 14, and the processed sample. The shelf management personal computer 16 is connected wirelessly or by wire. And a host computer 17 as a host apparatus which performs all location management and processing progress state management of each tray 81 in one or more trays 81 are.

In short, the sample management shelf system 11 includes a plurality of sample shelves for detecting the unique IDs of one or a plurality of placed trays 81 (a plurality of wafers 82 are mounted as production samples) by the gate

type RFID readers

12a and 15a. Pre-processing sample shelves 12 and post-processing sample shelves 15, a plurality of sample shelves with unique IDs assigned thereto, and each pre-processing sample shelf management personal computer 13 serving as each shelf management personal computer and A post-process sample shelf management personal computer 16 and a host computer 17 as a host device for managing the location information of one or a plurality of trays 81 via each shelf management personal computer are provided.

This sample management shelf system 11 is used in a manual conveyance process without an automated conveyance system. An RFID chip 83 is assigned to each tray 81, a unique ID is assigned to each tray 81, and the RFID chip 83 is stored and processed. Gate-

type RFID readers

12a and 15a as tray ID reader means are installed at both ends of each shelf in the front sample shelf 12 and the processed sample shelf 15 so that an operator can perform one or a plurality of trays 81 in the process. By simply performing an operation of placing a shelf on a shelf or taking one or a plurality of trays 81 from the shelf, the inventory status of all lots (real-time location management) for each shelf in the process can be obtained. , 15a to detect and grasp. Regardless of the stand-by sample shelf on which one or more trays 81 on which the production sample (wafer 82) is mounted, the gate

type RFID readers

12a and 15a for each shelf are used for the RFID chip 83 of the one or more trays 81. The pre-processing sample shelf management personal computer 13 and the post-processing sample shelf management personal computer 16 recognize and recognize what kind of sample (wafer 82) is placed on the standby sample shelf by detecting the unique ID. The data is transmitted to the host computer 17, and the sample management information of the host computer 17 is updated.

As described above, all the production samples (wafers 82) are managed in real time by the sample management shelf system 11 in real time. The sample to be produced (wafer 82) is mounted on the tray 81, and is transported and stored. The inventory of the wafers 82 other than the tray 81 is out of control. By collecting events from the

management computers

13 and 16, the host computer 17 updates the locations of all samples (all trays 81) in the process. In this case, the host computer 17 is not a large-scale CIM system, but a gate type RFID for placing one or a plurality of trays 81 on which a sample to be produced (wafer 82) is mounted on the pre-processing sample shelf 12 and the post-processing sample shelf 15. The worker's work is started with the point of time passing through the

readers

In short, one or a plurality of trays 81 on which the production sample (wafer 82) is mounted are placed on the pre-processing sample shelf 12, and processing by the processing apparatus becomes possible, and processing is started sequentially by FIFO. Further, when one or a plurality of trays 81 on which the production sample (wafer 82) is mounted are placed on the processed sample shelf 15, an instruction to carry to the next section is issued. The trigger is due to an event placed on the shelf.

In short, the pre-processing sample shelf 12 and the post-processing sample shelf 15 as sample shelves are gate-type RFID readers as tray reader means for reading the unique IDs of one or a plurality of trays 81 on which the production sample (wafer 82) is mounted. 12a and 15a, and the unique ID of one or a plurality of trays 81 read by the gate

type RFID readers

Then, the detection of the gate type RFID reader is used as an event trigger to update the lot location information of one or a plurality of trays 81 on which the production sample (wafer 82) is placed by communication with the host computer 17.

FIG. 5 is a schematic diagram showing the lot storage box 19 and the tray 81 on which the wafers 82 are placed.

In FIG. 5, when the wafer diameter is as large as several tens of inches, a plurality of wafers are accommodated in a cassette (sample box; lot storage box 19).

In the device manufacturing process, an environment in which a plurality of wafers are stored in a cassette (sample box; lot storage box 19) and transported or processed, or in a production process in an overseas factory, as described above, regardless of the sample box. In addition, the shelf management system can be expanded assuming that the wafers 82 are processed in the transport unit and form such as the tray 81.

In the process where the diameter of the wafer 82 is small, a plurality of wafers 82 are arranged on the tray 81 and this is called one unit (one lot). A shelf management system can be constructed with a view to transporting the tray 81 or transporting a plurality of trays 81 as a lump of a plurality of tray groups 81A.

When the diameter size of the wafer 82 is reduced to several inches, management from the sample box unit (cassette unit) to the tray unit is performed. It should be a shelf management system that assumes a process of transporting a plurality of trays 81 as a lump of a plurality of tray groups 81A from a conventional transport in the lot storage box 19 as a sample box (cassette).

Next, a sample management shelf system using the lot storage box 19 as a sample box (cassette) from the tray 81 will be described.

FIG. 6 is a perspective view schematically showing a standby sample shelf used in a sample management shelf system with a lot storage box 19 as a sample box.

In FIG. 6, a standby sample shelf 10A using a lot storage box 19 as a sample box, which is a cassette containing a plurality of large wafers, is assigned to each lot storage box 19 and assigned with a unique ID. Is read by the RF-ID reader 20 arranged for each predetermined area (shelf section) of the shelf, so that the lot storage box 19 is in which shelf of the standby sample shelf and in which partition position It is configured to detect whether it has been placed. The RF-ID reader 20 is arranged in a sample box (cassette) for each cassette. In short, the cassette lot storage box 19 (RF-ID tag 18) and the RF-ID reader 20 for each section of the shelf have a one-to-one relationship, but the tray 81 (RFID chip 83) and the gate-type RFID described above. The reader 10a is different from the case described above in that it is one-to-many (including one-to-one).

FIG. 7 is a schematic diagram showing an outline of work in a manual conveyance process using a sample box (cassette) in the first embodiment of the sample management shelf system in the production management system of the present invention.

As shown in FIG. 7, in the production management system of the first embodiment, the sample management shelf system 11A using a sample box (cassette) detects the presence or absence of a sample (lot) to be processed by each processing apparatus and stores it. The pre-processing sample shelf 12A, the pre-processing sample shelf management personal computer 13A for instructing the next processing on the navigation screen 13a for the sample (lot) detected on the pre-processing sample shelf 12A, and the sample ( The navigation screen 14a is used to instruct the operator on various information such as the set contents when the lot is taken out, transported to the processing apparatus and set in the processing apparatus, and the transport time when the processing is completed and the sample (lot) is taken out. Device management personal computer 14 to be performed and a sample (lot) processed by the processing device is transported from the processing device and placed A processed sample shelf 15A for detecting and storing a lot), and a processed sample shelf management personal computer 16A for instructing the sample (lot) detected on the processed sample shelf 15A to be transferred to the next process on the navigation screen 16a. These pre-processing sample shelf management personal computer 13A, apparatus management personal computer 14 and post-processing sample shelf management personal computer 16A are communicated wirelessly or by wire to manage all locations of samples (lots) and for each sample (lot). And a host computer 17 as a host device for managing processing progress.

In short, the sample management shelf system 11A includes the pre-processing sample shelf 12A and the post-processing sample shelf 15A as a plurality of sample shelves that detect the unique ID of the placed sample box (the lot storage box 19 containing the production sample). Each of the sample shelves is assigned a unique ID, and each pre-processing sample shelf management personal computer 13A and post-processing sample shelf management personal computer 16A as each shelf management personal computer provided for each sample shelf, and each shelf management personal And a host computer 17 as a host device for managing the location information of the sample box via each computer.

This sample management shelf system 11A is used in a manual conveyance process without an automated conveyance system, and an RF-ID tag 18 is added to a lot storage box 19 and a unique ID is assigned to each lot storage box 19 to prepare a sample before processing. The standby sample shelf (pseudo stocker), which is the shelf 12A and the processed sample shelf 15A, is equipped with an RF-ID reader 20 as a sample box ID reader means for each section of the shelf, and an operator shelves the sample in the process. It is possible to detect and grasp the inventory position status (real-time location management) of all lots in the process by simply performing a simple operation of placing the sample in the section or taking the sample from the shelf section. The RF-ID reader 20 for each shelf section detects the RF-ID tag 18 of the lot storage box 19 regardless of the section of the standby sample shelf where the lot storage box 19 containing the production sample (lot) is placed. The pre-processing sample shelf management personal computer 13A and the post-processing sample shelf management personal computer 16A recognize what kind of produced sample (lot) has been placed in the section of the standby sample shelf and recognize this in the host computer 17. Then, the sample box management information as the sample management information of the host computer 17 is updated.

As described above, the location management of all production samples (lots) is performed in real time by the sample management shelf system 11A. The produced sample (lot) is put in the lot storage box 19 to be transported and stored, and the inventory other than the lot storage box 19 which is a storage box is out of management. By collecting events from each management computer, the host computer 17 updates the location of all samples in the process. In this case, the host computer 17 is not a large-scale CIM system, and is triggered by the time when the lot storage box 19 containing the produced sample (lot) is placed on the pre-processing sample shelf 12A and the post-processing sample shelf 15A. Work begins. In short, when the lot storage box 19 containing the sample to be produced (lot) is placed on the pre-processing sample shelf 12A, processing by the processing device becomes possible, and processing is sequentially started by FIFO. Further, when the lot storage box 19 containing the sample to be produced (lot) is placed on the processed sample shelf 15A, an instruction to carry to the next section is issued. The trigger is due to an event placed on the shelf.

In short, the pre-processing sample shelf 12A and the post-processing sample shelf 15A as sample shelves include an RF-ID reader 20 as a sample box ID reader means for reading a unique ID of a sample box containing a production sample (lot). The unique ID of the sample box (cassette) read by the RF-ID reader 20 is a host as a host device via the pre-processing sample shelf management personal computer 13A and the post-processing sample shelf management personal computer 16A as a shelf management personal computer. Information is provided to the computer 17 so that the location information of the sample box is updated. That is, when the operator places the sample box on the sample shelf and when the operator takes out the sample box from the sample shelf, the RF-ID reader 20 for each section of the shelf sets the RF-ID tag 18 for each sample box. Based on the read sample box ID information, the location information of the sample box is uploaded in real time from the shelf management

personal computers

13A and 16A to the host computer 17 as the host device.

The sample shelf is provided with ID reader means (tray ID reader means or sample box ID reader means) for reading the unique ID of a sample container (sample case) such as the tray 81 or sample box. The location of the sample container (sample case) based on the container ID information read by the ID reader means during the work of placing the (sample case) and the work of the operator taking out the sample container (sample case) from the sample shelf Information is uploaded from the shelf management personal computer to the host device in real time.

Next, the shelf management personal computer holds the manufacturing flow and processing device information, and the progress information of the flowing production sample. From the detected unique ID of the sample container (sample case) such as the tray 81 and the sample box, Next, the processing device to process the sample (lot (product material) and wafer here) in the sample container (sample case) is determined, and the transport destination of the sample container (sample case) is displayed on the display screen. The worker instruction management that instructs the worker will be described with reference to FIG.

FIG. 9 is a layout diagram showing a state where workers and lots flow through each processing step in the worker instruction management of the production management system of the first embodiment.

As shown in FIG. 9, each processing process includes a photolithographic process, a wet etching process, an inspection process, and an MOCVD process. A standby sample shelf indicated by “IN” and “OUT” is provided for each processing process. ing. The standby sample shelf indicated by “IN” is a pre-processing sample shelf, and the standby sample shelf indicated by “OUT” is a post-processing sample shelf.

In order to perform a predetermined process, a sample container (sample case) such as a tray 81 or a sample box containing a production sample (lot) is placed in a sample shelf (IN sample shelf 12, 12A) of “IN”. Further, in order to perform the next processing, a sample container containing a sample to be produced (lot) is taken from the “OUT” sample shelf (processed

sample shelves

15 and 15A), and the “IN” pre-process sample shelf in the next process is taken. Transport to. There is a processing device in each process, and an operator in each process takes a sample container containing a production sample (lot) placed on the pre-processing sample shelf of “IN” and puts the production sample ( Lot) is set and predetermined processing is performed. When the processing by the processing apparatus is completed, a sample container containing the processed sample (lot) after processing is placed on the processed sample shelf of “OUT”. The worker who transports the sample container containing the processed sample to be processed (lot) placed on the sample shelf after the processing of “OUT” and whose lamp is lit, performs the next process “ The sample container containing the produced sample (lot) is transported to the pre-processing sample shelf of “IN”.

The process in this case is divided into a plurality of sections for each process, and an “IN” pre-processing sample shelf and an “OUT” post-processing sample shelf are arranged in each section. There is no automatic transfer system (transfer robot or storage stocker) in and between these processes, and this is a manual production process.

The plurality of standby sample shelves are arranged in sections divided for each process, and one or a plurality of pre-processing sample shelves and one or a plurality of post-processing sample shelves are arranged in each section.

Employees are assigned full-time workers (for example, photo staff, inspection staff, CVD staff, etc.) distinguished for each section. A dedicated worker for transporting the production sample (lot) between the sections is also arranged. Each worker has a unique skill for each section, and has a skill rank according to their experience. These workers perform in-process work and transfer work according to the instruction content displayed on the display screen of the shelf management computer arranged for each section. The worker has an ID that can identify an individual.

By utilizing 14a and 16a, a new worker (worker of an overseas factory) can work.

Also, each shelf management computer has a function of counting up the time from instruction to execution in order to monitor the work delay of each worker. The purpose of this is to improve the work efficiency of the worker by counting up the passage of time and to collect information on skill determination and lead to stable production. The calculation of the elapsed time is counted up from the time when the work instruction is performed (the time when the screen is displayed). For this time, for example, the time setting is level 1 for up to 3 minutes, level 2 for up to 5 minutes, and level 3 for up to 10 minutes. The difference from the past average elapsed time is taken as one of the evaluation methods. The number of level 3 is used as one of the evaluation deduction items of the worker. The worker only performs the instructed work without any work mistakes and without delay, and does not require the skill level of the worker.

In short, the pre-processing sample shelf management

personal computers

On the other hand, the worker puts (or mounts) a sample (lot) that has been processed by the processing apparatus into a sample container (sample case) such as the tray 81 or the lot storage box 19 and carries it from the processing apparatus. It is conveyed to the

rear sample shelves

15 and 15A. As described above, the time is managed by the timer so that there is no delay in the work of carrying out the sample (lot) from the processing apparatus to the

sample shelves

15 and 15A after the transfer processing of “OUT”.

Processed when waiting for the next process of a sample container (sample case) such as the tray 81 or the lot storage box 19 containing the produced samples (lots) placed on the

sample shelves

15 and 15A after the transfer process of “OUT” The rear sample shelf management

personal computers

16 and 16A display the transport time on the navigation screen 16a and instruct the operator to count down. On the other hand, the operator places the sample container (sample case) such as the tray 81 or the lot storage box 19 placed on the

sample shelves

15 and 15A after the “OUT” transfer process before the process “IN” in the next process. The sample is transferred to the sample shelves 12 and 12A. As described above, the time is managed by the timer so that there is no delay in the operation of transporting the sample (lot) from the

sample shelves

15 and 15A after the transfer process of “OUT” to the sample shelves 12 and 12A before the process of “IN”. .

When waiting for the start of processing of a sample container (sample case) such as the tray 81 or the lot storage box 19 placed on the pre-processing sample shelves 12 and 12A of “IN” in this step, the pre-processing sample shelf management

personal computer

13, 13A displays the processing start time on the navigation screen 13a and counts down to the worker. On the other hand, the operator takes out a production sample (lot) from a sample container (sample case) such as the tray 81 or the lot storage box 19 placed on the pre-conveyance sample shelves 12 and 12A of “IN”. A production sample (lot) is set in a predetermined processing apparatus. In this way, time management is performed by the timer so that there is no delay in the work of carrying out the sample (lot) from the processing apparatus. In this manner, the time is managed by the timer so that there is no delay in the processing start work of the sample (lot) from the pre-conveyance sample shelves 12 and 12A of “IN” to the set of processing apparatuses.

Next, the device management personal computer 14 displays the processing start time on the navigation screen 14a and counts down to the worker. On the other hand, when the worker starts processing and a production sample (lot) processed by a predetermined processing device is waiting to be carried out, the device management personal computer 14 displays the carrying-out time on the navigation screen 14a. And display the countdown to the worker. On the other hand, the operator puts (or mounts) a sample (lot), which has been processed by the processing apparatus, into a sample container (sample case) such as the tray 81 or the lot storage box 19 from the processing apparatus. Are transferred to the

sample shelves

FIG. 11A shows the

navigation screens

13a, 14a and 16a of FIGS. 3 and 7 as work error prevention screens in addition to the work instruction screen and the delay screen, and FIGS. 11B and 11C show the work screens. The average work time comparison chart, FIG. 11 (d) is a group-by-group process performance ranking chart.

As shown in FIG. 11A, the case where the

navigation screens

13a, 14a and 16a of FIGS. 3 and 7 are used as the next work instruction screen and the delay prevention screen has been described. However, the navigation screen 13a of FIGS. , 14a and 16a can be used for the work error prevention screen. For example, when a sample (lot) that is not expected by the system is placed on the pre-processing sample shelves 12 and 12A of “IN”, the gate-type RFID reader 10a and the RF-ID reader 20 of the shelf are replaced with the RFID chip 83 and the lot of the tray 81. The pre-processing sample shelf management

personal computer

13 or 13A or the post-processing sample shelf management personal computer detects what kind of produced sample (lot) is placed on this standby sample shelf by detecting the RF-ID tag 18 in the storage box 19. Although the

computers

16 and 16A recognize that it is wrong, a display such as “Lot A; Operation error” is displayed on the

navigation screens

13a, 14a and 16a in FIG. Originally, it is designed to display on the screen which shelf or processing device should be transported. Normally, when the produced sample (lot) is placed on the pre-processing sample shelves 12 and 12A of “IN”, the pre-processing sample shelves 12 and 12A detect the produced sample (lot) and a work instruction screen is displayed. Although what kind of processing is performed in the lever is displayed, if a mistake is made, a “work error” is displayed as a warning. As a result, the worker can instruct the system to display a warning for an operation that the system does not expect and to correct the work correctly so that “work mistakes” can be prevented at an early stage. In short, when processing sample (lot) is to be processed by processing device A, it is possible to correctly instruct the operator that it is processing device B by mistake. This system correctly guides any worker so that the work is not delayed and no mistakes are made.

As shown in FIG. 11 (b), the transport delay time for each apparatus and the average daily work time for each day as shown in FIG. 11 (c) are totaled by the host computer 17, and as shown in FIG. The separate processing result ranking is totaled by the host computer 17.

The host computer 17 aggregates events for each worker, and displays and outputs navigation information for improving work awareness via the

navigation screens

13a, 14a and 16a of the shelf management personal computer. For example, it is possible to give each worker a sense of competition with the best 10 display that can evaluate the processing performance of each section and each worker. Production managers (team leaders and line heads) can visualize the processing results for each work section, and use it as decision-making materials such as personnel increase / decrease and placement. Furthermore, when there is a difference event input with respect to the warehousing instruction and the warehousing instruction, it has a function of checking and a function of displaying this on the display screen.

As described above, according to the first embodiment, the pre-processing sample shelf 12 as a plurality of sample shelves for detecting the presence or absence of the unique ID of the sample container (sample case) such as the placed tray 81 and / or the lot storage box 19. , 12A and

post-processing sample shelves

15, 15A, and pre-processing sample shelves 12, 12A and

post-processing sample shelves

15, 15A as a plurality of sample shelves are assigned unique IDs, respectively. Pre-processing sample shelf management

personal computers

13 and 13A and post-processing sample shelf management

personal computers

In this way, a tray in which a sample to be produced (lot) is contained (or placed) only by an operation in which an operator places sample containers (sample cases) such as the tray 81 and the lot storage box 19 on the shelf and removes them from the shelf. Whether the sample container (sample case) such as 81 or the lot storage box 19 is on the shelf is detected by the wireless communication function, and the produced sample (lot) in the sample container (sample case) such as the tray 81 or the lot storage box 19 is detected. ) Location information can be collected from all shelves by host equipment, and low-investment, on-line management of the entire production sample (lot) in a small-scale line or locally distributed line be able to. As a result, it is possible to achieve work efficiency and prevent work errors by performing navigation for work management and labor saving in a production line with a manual transport / offline device.

In addition to production lines with mixed manual transfer / offline equipment, production lines that are premised on offline processing in an inexpensive labor environment, production lines that minimize the amount of investment without automating small-scale production, and transport automation systems ( In a production line or the like that does not include a transfer robot and a lot stocker, navigation for work management and labor saving can be performed to improve work efficiency and prevent work mistakes.

Although not specifically described in the first embodiment, the sample

management shelf systems

11 and 11A of the first embodiment and the sample management shelf system obtained by mixing them are used on a production line with a manual transport / offline device. By managing information and sample location information online, and performing a navigation function to prevent work loss and work mistakes and save labor, it is possible to manage pseudo online management even for production lines with offline equipment. Can be applied to a production management system that can be realized efficiently. Such a production management system will now be described in detail.

FIG. 15 is a flowchart showing an operation example of the production management system 1 including the worker's work process when the production process is performed using the production management system 1 of FIG.

First, as shown in FIG. 15, in step S <b> 1, the operator operates the stocker management personal computer 51 constituting the data card giving apparatus 5 to select “card output information”. As the “card output information”, an operator is instructed which cassette (lot) is taken out from which stocker and to which processing apparatus is manually conveyed. Here, a lot storage box 19 (sample box) which is a cassette (lot) is targeted, but a tray 81 on which a plurality of wafers 82, chips, modules, and the like are mounted may be used together with or separately from this. .

Next, in step S2, the operator operates the stocker management personal computer 51 to print out the data card 53 from the data card printer 52.

Subsequently, in step S3, the worker issues the instructed cassette (lot) from the source stocker 54 in accordance with the contents of the data card 53 printed out.

Thereafter, in step S4, the operator manually transports the delivered cassette (lot) to a predetermined processing apparatus.

Further, in step S5, the worker reads the contents of the worker card (worker ID, assigned area, work rank (work skill and work history information)) with the card reader 4. Also, the worker manually conveys the work card. The cassette (lot) is set in the apparatus loader and the contents of the data card 53 are read by the card reader 4. That is, the operator sets the cassette (lot) in the processing apparatus as “set cassette”. By making the data card approach the card reader 4 provided in the processing apparatus, the “lot ID / process reading” is performed, and the lot ID to be processed in the processing apparatus and the process contents are read accurately without any mistake. 4 can be read.

In the above steps S1 to S5, the operator executes an event instructed by the stocker management personal computer 51 and the data card 53, and at the same time, the operator's work is to cause the card reader 4 to read the contents of the worker card and the data card 53. It is.
