The present invention relates to a program up-update method of a semiconductor process management system. More specifically, the program of a client server for controlling and monitoring the progress of a semiconductor process in a semiconductor manufacturing line is regularly updated. And a program up-date method for up-date semiconductor process management systems.

A general semiconductor device requires a high degree of precision, and accordingly, in a typical semiconductor production line, a predetermined facility capable of precision processing, for example, a photo facility, a sputtering facility, an etching facility, a measurement facility, and the like, is disposed of most manufacturing processes. I'm doing it.

At this time, each facility is provided with a predetermined client server, and the worker improves the efficiency of facility management by appropriately controlling the operation status of each facility through such a client server.

At this time, the individual worker performs a predetermined computer operation on each client server, and operates an automatic transfer system such as a robot, whereby a lot is loaded into a port provided in the facility and undergoes a predetermined process.

On the other hand, each facility and client server is networked with a host server having a data collection function and a data providing function.

Accordingly, various data related to each facility are input and stored in the host server, and the operator can log in or contact the host server from each individual client server to perform a predetermined computer operation desired by the user.

Each of these facilities and client server are communicated by a predetermined protocol, and the client server and host server are communicated by well-known TCP / IP.

The client server is operated as a main program downloaded from the host server, and the host server is updated with new programs input from time to time.

The client server must download the upgraded new program from the host server. The conventional download method is as follows.

The operator terminates the current process progress program, downloads the updated new program from the host server to the client server through the network, and stores it in each client server. The client server overwrites the updated new program with the existing program. Updating of the client server proceeded in the order of overwriting.

Updating in the above manner requires the operator to operate all of the above steps, which increases the workload of the worker and the programs of the client server in the line by not updating the client servers at the same time. Different versions occur, and the host server that manages the entire line is not smoothly controlled.

An object of the present invention is to automatically update a client server used in a semiconductor line to a new version of the program without manual manual update by the operator.

Another object of the present invention is to perform the update operation of the client server at the same time at the same time so that the program version of the entire client server is always kept the same version.

The object of the present invention will be explained in more detail by the following figures and description.

In the system according to the present invention, a host server and a plurality of client servers are connected by a network, and whenever a data version on the host server is updated, a new version is registered in real time with the host server. A version check function is executed to check whether a newly registered version is present on the host server. If the versions of the client server and the host server are different from each other, the client server has a step of implementing a download function and a registration function. It features.

The construction and operation of the present invention will become more apparent by the following description.

1 is a block diagram showing an embodiment according to the present invention.

In the embodiment according to the present invention, the host server 10 and the plurality of client servers 101, 102, 103 ,, and N are connected by a network. (N is any natural number.)

The host server 10 is configured with a database for storing and managing data provided in an embodiment of the present invention (not shown), and the plurality of client servers 101, 102, 103,, N through a network. Whenever a version of the data is updated in connection with the host server 10, a new version is registered in real time.

A plurality of client servers 101, 102, 103, and N can be installed in parallel on a network, and all the client servers 101, 102, 103, and N are connected to a host server 10 through a network connected in parallel. )

And, the client server (101, 102, 103 ,,, N) has a version checking function to recognize whether there is a version newly registered on the host server 10 by recognizing the time when the version checking time, the version As a result of the check, if the versions of the client server (101, 102, 103 ,,, N) and the control server 10 are the same, there is no need for an update, the process continues to the current version.

In addition, when the versions of the client server 101, 102, 103,, N and the host server 10 are not the same, the client server 101, 102, 103,, N performs a download function. If the system file exists in the received file, the register registration function is executed.

FIG. 2 is a flow chart showing an embodiment of a program up-update method of a semiconductor process management system according to the present invention, in which the client servers 101, 102, 103, and N of FIG. The process of performing the download function, the register registration function.

The client server (101, 102, 103 ,,, N) checks frequently whether it is a version checking time (S10).

The version checking time is a time designated in advance to perform an operation for comparing and checking the program version on the client server 101, 102, 103,, N and the program version on the host server 10 at a predetermined time.

If it is not the version checking time in step S10, the client server (101, 102, 103 ,,, N) repeats the checking process of the version checking time after waiting a predetermined waiting time (S12), and if the version checking time, The client server (101, 102, 103 ,,, N) checks the version of its program (S20).

The result of the version check in step S20 is compared with the program version on the host server 10 to confirm whether it is the same version (S30).

If the result of comparison in step S30 is found to be the same version, the downloading process is unnecessary, so the process ends.

However, if it is confirmed that the result of the version check in step S30 is not the same version, the client server (101, 102, 103 ,,, N) is a series of steps below S40 to download a new version of the program from the host server (10) Proceed with the sequence of.

That is, the client servers 101, 102, 103 ,, and N first terminate the process program currently in progress (S40).

The client server (101, 102, 103 ,,, N) calls the download program to download a new version of the program from the host server (10) (S50).

The client servers 101, 102, 103 ,, and N download and store a new version of the program stored in the host server 10 as the called download program.

The download program called from the client servers 101, 102, 103,, N receives the program name and location information of the new version registered in the host server 10, and then the client server 101, 102, 103, After confirming the name and location information of the corresponding program in ,, N), the program corresponding to the corresponding position is downloaded.

The client server (101, 102, 103 ,,, N) determines whether a system file exists among the files constituting the downloaded program (S70).

If it is determined in step S70 that a system file exists among the files constituting the downloaded program, a file for starting the downloaded program is added to the startup program (S80).

The system of the client servers 101, 102, 103, ,, N is restarted (S90).

When the system of the client server (101, 102, 103 ,,, N) is restarted (S90), a file for starting the downloaded program is executed and the updated system file is automatically registered in the register (S100).

When the system file is registered in the register (S100), the file that starts the downloaded program is removed from the startup program (S110).

The downloaded program is executed (S120).

If the system file does not exist among the files constituting the program downloaded in step S70, the client server 101, 102, 103 ,, N executes the downloaded program.

If the downloaded program is successfully executed (S120), the above process is terminated.

Since the update process proceeds in the same order as described above, the client server 101, 102, 103,, N is performed by an automatic operation that is automatically executed when the client server 101, 102, 103,, N reaches a predetermined time. Version mismatch of client servers (101, 102, 103 ,,, N) does not occur due to the missing of manual update operation of all client servers (101, 102, 103 ,,, N) at the same time. -As it is updated, it becomes smooth for the host server 10 to control the entire line.

Although the above description describes the update method of the client server and the host server in the semiconductor manufacturing line, the method according to the present invention can be applied to all fields using the client server and the host server as well as the semiconductor manufacturing line.

As described in detail above, it will be appreciated that those skilled in the art can carry out various modifications or changes of the present invention without departing from the spirit and scope of the present invention. There will be.

Comparing the program update method of the semiconductor process management system according to the present invention with the conventional update method, the update method according to the present invention automatically checks the version, downloads, and registers the client server when the update time comes. Since the worker does not have to perform the update process of the client server, there is an effect that the manual work of the worker is reduced.

And since all client servers are updated at the same time, all client servers in the entire line always have the same version of data, so that the control of the host server that manages the whole work area is seamlessly performed.
