And a substrate processing system including the information.

In general, this type of substrate processing system includes a plurality of substrate processing apparatuses for processing a substrate, and information (data) such as monitoring of a state of operation of the plurality of substrate processing apparatuses and a production history. It consists of a group management server (information management apparatus) which manages this. Therefore, the information management apparatus manages various types of information such as measured values such as temperature, pressure, gas, and operation status transmitted from the substrate processing apparatus. By such an information management apparatus, the efficiency of semiconductor production is aimed at. The user acquires the information managed by the information management apparatus using the terminal device.

However, in the conventional substrate processing system, the terminal apparatus may take time to acquire information from the information management apparatus.

This invention is made | formed in order to solve the above-mentioned subject, and an object of this invention is to shorten the time which a terminal apparatus acquires information from an information management apparatus.

A first information management method according to the present invention is an information management method for managing information based on a full text including device information or event information transmitted from a substrate processing apparatus for processing a substrate, the device information including device information. The device information of the substrate processing apparatus at the time when the full text is transmitted is stored in the first device information storage means, and when the full text including event information is transmitted, the event information and the condition for storing the device information are compared. If the match is found, the device information and the time at which the event information occurred are stored in the second device information storage means.

The second information management method according to the present invention is a moving condition for moving the event information and the device information stored in the first device information storage means to the second device information storage means when the full message including the event information is transmitted. And the condition storage means for which the device information to be moved is set, and when the event information and the condition match, as the device information stored in the first device information storage means, the event is added to the set device information of the moving object. The time at which the information occurred is added and stored in the second device information storage means.

The information display method according to the present invention is an information display method for displaying information to an operation terminal having an operation screen, and when the full message including event information is transmitted from the substrate processing apparatus for processing the substrate, By referring to the moving condition for moving the event information and the device information stored in the first device information storage means to the second device information storage means and the condition storage means for which the device information of the moving target is set, the device information of the moving target is set. The second device information storage means is searched by adding the time at which the event information has occurred, and the searched result information is compared with the set device information, and if it matches, the device information is displayed on the operation screen.

According to the present invention, when the terminal apparatus acquires information from the information management apparatus, the time required for searching can be shortened. Then, using various information generated when the substrate is processed in the substrate processing apparatus, data analysis (eg, abnormality caused by abnormalities generated in the substrate processing apparatus, etc.) and data processing (eg, the substrate Time for performing graphing of production information transmitted from the processing apparatus, etc. can be shortened.

First, the background of this invention is demonstrated based on FIG.

1 is a diagram showing device information stored in a conventional group management server, its structure, and a retrieval method of stored device information.

FIG. 1A is a diagram illustrating the full text transmitted from a substrate processing apparatus. As illustrated in FIG. 1A, each full text includes the transmitted time, the name (device name) of the substrate processing apparatus of the sender, the item type, and the information (measured value, etc.) of the item. The group management server receives a telegram transmitted from a plurality of substrate processing apparatuses, obtains device information from the telegram, and stores the device information.

1B is a diagram schematically showing a structure in which device information is stored. As shown in Fig. 1B, the device information is stored in the database DB. The DB includes an item management table, a measurement data management table, and a device management table. In the item management table, each item corresponding to the item type is managed. In the apparatus management table, each substrate processing apparatus is managed. In the measurement data management table, information (measured values, etc.) related to items managed in the item management table and devices managed in the device management table, and time included in the full text (corresponding to 'time' in FIG. 1 (A)) are managed. do.

The merit of this DB structure is as follows. That is, 1) there is no effect on the DB structure even when an item is added (for example, a new table must be added), and 2) an effect on the DB structure even when a substrate processing apparatus is added. 3) Even when each substrate processing apparatus includes different items, the device information is managed by the measurement data management table. 4) The measurement data management table includes information on items included in the substrate processing apparatus (measured values, etc.). ) Is stored, there is no unnecessary data area.

1C shows a method of acquiring device information stored in a DB. For example, when confirming the state of the substrate processing apparatus (the failure generating device) at the time of the occurrence of the failure, the terminal device as the operation terminal refers to these three tables with reference to the item management table, the measurement data management table, and the device management table of the DB. Is reconstructed as a table illustrated in FIG. 1C, and in the table of FIG. Here, since the measured values of all items are not limited to each time, when the measured values are not stored at a desired time, it is necessary to retrospect to the time at which the measured values are stored.

Specifically, the terminal apparatus needs to perform the supplementary work of the measured value from the desired time to the time at which the measured value is stored for each item. For example, the terminal device can retrieve the value (690.0) of the temperature ch1 at time 12:00:04, but cannot retrieve the value of the temperature ch2 and the gas ch1, but the value of the temperature ch2 and the gas ch1 In order to retrieve the value, it is necessary to retrospect it by time 12:00:02.

Thus, this DB structure has the following demerit. That is, 1) it takes time to reconstruct a plurality of related tables as one table for data retrieval, and 2) it takes time to interpolate measurement values.

The group management server 4 is configured to be connected to the display / input device 24 of the terminal device 6 via the communication IF 22.

Next, the functions of the group management server 4 and the DB structure and the functions of the terminal device 6 will be described.

FIG. 7 is a diagram showing the functional configurations of the group management program 40 executed by the group management server 4 and the terminal program 60 executed by the terminal device 6.

As shown in FIG. 7, the group management program 40 includes a device information DB 400, a current information storage unit 402, a definition information storage unit 404, a communication unit 406, and a specialized reception unit 408. ) And a device information registration unit 410. The group management program 40 is loaded into the memory 20 of the group management server 4 and executed on an OS (not shown) operating on the control device 16.

In the group management program 40, the current information storage unit 402 (first device information storage means) stores the latest device information of each substrate processing apparatus 10. Specifically, the current information storage unit 402 stores the device information at the time when the full text is transmitted based on the full text transmitted from the substrate processing apparatus 10. The device information includes production information such as device identification information, temperature information, pressure information, gas information, and measurement data for each production information. The current information storage unit 402 (first device information storage means) stores the measured values with respect to all the device information of each substrate processing apparatus 10 obtained from the full text. The current information storage unit 402 is realized by the memory 20.

The device information DB 400 (second device information storage means) stores device information and time in association with each substrate processing apparatus 10. Specifically, the device information DB 400 stores, as part of the device information, the device information defined by the definition information storage unit 404 described later for each time the defined event information occurs. The device information DB 400 is realized by at least one of the memory 20 and the storage device 26.

The definition information storage unit 404 is stored so that the definition information can be changed. The definition information includes a condition (accumulation condition) in which the device information stored in the current information storage unit 402 is read and accumulated in the device information DB 400, the device information displayed on the terminal device 6, and the like. For example, the accumulation condition includes occurrence of a predetermined event. For example, the device information displayed by the terminal device 6 includes the type of production information such as "temperature ch1", "temperature ch2" and "gas ch1" and the measured value of each production information. On the other hand, the definition information storage unit 404 may store a plurality of definition information. In this case, the group management program 40 preferably has the device information DB 400 for each definition information.

The communication unit 406 performs communication processing required for communication with the substrate processing apparatus 10. Specifically, the communication unit 406 acquires the full text transmitted from the substrate processing apparatus 10 via the communication IF 22 in a predetermined order, and outputs the full text to the full text reception unit 408.

The full-text accepting unit 408 accepts a full-text output from the communication unit 406, and when the full-text includes the device information, causes the current information storage unit 402 to store the device information. Specifically, the full text acceptor 408 updates the measured value of the device information included in the full text output from the communication unit 406 among the device information currently stored in the information storage unit 402. For example, the full text accepting unit 408 overwrites the measured value of the device information included in the full text with the measured value currently stored in the information storage unit 402. As a result, the current information storage unit 402 stores the device information of the time point at which the full text was transmitted, that is, the latest substrate processing apparatus 10.

In addition, when the telegram received from the communication unit 406 includes event information, the telegram acceptor 408 outputs the event information to the device information registration unit 410.

The device information registration unit 410 refers to the definition information storage unit 404, and stores the device information stored in the current information storage unit 402 according to the accumulation condition stored in the definition information storage unit 404. Register in the information DB (400). Specifically, the device information registration unit 410 is a source of transmission of event information when the event information output from the full-text reception unit 408 and the event information stored as the accumulation condition in the definition information storage unit 404 match. The device information of the substrate processing apparatus 10 is read from the current information storage unit 402, and at least a part of the read device information is registered in the device information DB 400 in association with the time at which the event occurred. Here, the device information registration unit 410 refers to the definition information stored in the definition information storage unit 404, reads only the defined device information, and processes and registers the information so that the information is organized into a predetermined data format. As a result, whenever an event as an accumulation condition occurs in the substrate processing apparatus 10, device information of the substrate processing apparatus 10 at the time of occurrence is accumulated in the device information DB 400.

The terminal program 60 has a user interface (UI) unit 600, a device information acquisition unit 602, and a screen generation unit 604. The terminal program 60 is loaded into the memory 20 of the terminal device 6 and executed on an OS (not shown) operating on the control device 16.

In the terminal program 60, the UI unit 600 (display means) receives the input content via the display / input device 24 and outputs it to the device information acquisition unit 602. For example, the UI unit 600 receives identification information such as the name and identifier (ID) of the substrate processing apparatus 10 and the time. The UI unit 600 also displays, on the display / input device 24, the obstacle information screen (described later) generated by the screen generation unit 604.

The device information acquisition unit 602 retrieves the device information stored in the device information DB 400 based on the identification information and the time output from the UI unit 600, and identifies the substrate processing device by the identification information. The device information at the time of (10) is acquired. The device information acquisition unit 602 outputs the acquired device information to the screen generation unit 604.

The screen generation unit 604 refers to the definition information storage unit 404 to obtain the type of the defined device information and the measurement value of each device information. The screen generating unit 604 generates a screen configuration of the fault information screen based on the type of the device information. The screen generation unit 604 synthesizes the device information acquired by the device information acquisition unit 602 into the screen configuration of the failure information screen to generate a failure information screen. The screen generating unit 604 outputs the generated obstacle information screen to the UI unit 600. The fault information screen will be described later in detail.

While processing the substrate, the substrate processing apparatus 10 transmits the full text including the device information of the substrate processing apparatus 10, such as temperature information, pressure information, and gas information, to the group management server 4. In addition, the substrate processing apparatus 10 transmits event information to the group management server 4 whenever an event occurs.

Next, the operation of the group management server 4 according to the embodiment of the present invention will be described.

9 is a flowchart showing an operation S10 of the military management server 4 according to the embodiment of the present invention.

As shown in FIG. 9, in the group management server 4 (group management program 40), the communication unit 406 determines whether or not a full text is received from the substrate processing apparatus 10. If the military management server 4 receives the full text, the processing proceeds to step 102 (S102), and otherwise, the processing ends.

In step 102 (S102), the communication unit 406 outputs the full text to the full text accepting unit 408, and the full text accepting unit 408 determines whether the event information is included in the output full text. When event information is included in the preamble, the military management server 4 proceeds to the processing of step 106 (S106), and otherwise proceeds to the processing of step 104 (S104).

In step 104 (S104), the full text accepting unit 408 updates the data of the device information included in the full text among the device information currently stored in the information storage unit 402. After the data update, the military management server 4 returns to the process of step 100 (S100).

In step 106 (S106), the full text accepting unit 408 outputs event information included in the full text to the device information registering unit 410, and the device information registering unit 410 designates this event information as an accumulation condition. It is determined whether there is. If the event information is designated as the accumulation condition, the group management server 4 proceeds to the processing of step 108 (S108), and otherwise returns to the processing of step 100 (S100).

In step 108 (S108), the device information registration unit 410 reads the information about the substrate processing apparatus 10 of the transmission source of the event information as the device information currently stored in the information storage unit 402, and the device information. Is associated with the event occurrence time and accumulated in the device information DB400. After the accumulation, the group management server 4 returns to the processing of step 100 (S100).

As described above, in the group management server 4, the latest information among the device information from the substrate processing apparatus 10 is once stored in the current information storage unit 402, and stored in the current information storage unit 402. Of the information, only the information related to the event defined by the definition information of the definition information storage unit 404 is accumulated in the device information DB 400, but the operation in the group management server 4 is not limited to this. .

For example, in the group management server 4, only the device information defined by the definition information among the device information from the substrate processing apparatus 10 with reference to the definition information of the definition information storage unit 404 in advance is presently present. Of the information stored in the information storage unit 402 and currently stored in the information storage unit 402, only information on an event defined by the definition information of the definition information storage unit 404 is provided in the device information DB 400. It may accumulate.
