2. Description of the Related Art In the production of semiconductors of various types and in small quantities, manufacturing process conditions such as process flows, equipment conditions, inspection specifications, photomask specifications, etc., have been managed by either computer system creation management or manual management. . However, in the case of computer management, JP-A-63-200520 and JP-A-63-200520
Although there are reports on the creation of semiconductor process flows, registration of manufacturing conditions, and changes, as in the description example of 280411, there is no mention of a search / comparison method aimed at extracting those differences. On the other hand, in the paper-based manual management method, (1) since the process names and the titles of the manufacturing conditions are not always standardized, the existing existing management information cannot be smoothly searched; In addition, even if a search can be performed, the definition content, description range, method of summarization, etc. are not necessarily constant depending on the designer and cannot be understood. (3) Therefore, the manufacturing process flow for each lot, reference process, and product type selected -And the production conditions cannot be compared smoothly. Therefore, there is a need for a system for managing and efficiently performing search and comparison on a computer system while standardizing and standardizing the semiconductor manufacturing process specifications.

A description will now be given of a method of comparing manufacturing process conditions using the search and comparison program 23 in the present system. In FIG. 3, two types of manufacturing process flows A and B are arbitrarily selected from the condition database 25 shown in FIG. 2, and one of them is used as a comparison reference and the other is compared (here, A is a comparison reference and B is a comparison reference). A method of extracting the difference between B and A is described below. In this system, both main processes 31a, 41a
In addition, a point at which the process codes of the first work processes 32b and 42b coincide with each other is searched and confirmed, and a comparison start point is set. Next, from the starting point, the differences between the manufacturing process flow 40 of B and the manufacturing process flow A of A are compared with those of the main process and each work process in order by the process code and the standard code. While comparing, point out the differences each time. According to such a procedure, in the present system, the operation steps shown in FIG. 3 are redundant to the point that the total number of operation steps is different. Also here,
As the basis for the judgment on the differences, the main processes are the same and the same position, the number of work processes in them, the arrangement order is the same, and so on. It is set to compare within the range. The differences pointed out are recorded until the execution of the comparison program 23 in the present system in order to reuse the printing and display.
