Abstract

This program permits artwork generator input data to be verified before inputting to an artwork generator, e.g., program light table and the like. Verification ensures the generation of correct artwork for fabricating semiconductor devices and related products. The program is performed in conjunction with an IBM 1130 and an IBM 2250 display terminal.

Checking Input Data to an Artwork Generator

This program permits artwork generator input data to be verified before inputting to an artwork generator, e.g., program light table and the like. Verification ensures the generation of correct artwork for fabricating semiconductor devices and related products. The program is performed in conjunction with an IBM 1130 and an IBM 2250 display terminal.

The program is initialized in an operation 10. An operation 11 establishes display coordinates for the 2250. The coordinates define an area identified as a window and an origin or center point. A data section indicator is set to 1 in an operation 12 (I = 1). A storage address of a graphical message is provided as an input to the 1130 in an operation 13. The data section indicator is retrieved and interpreted in an operation 14. A portion or word of the data section in storage is processed in an operation 15. A decision 16 is executed to determine whether the portion is the last word in the graphical message. A "NO" decision results in the data being stored in a buffer and displayed on the 2250 in an operation 18. The 2250 functions in a normal manner to display each point of the data in the buffer. A decision 20 checks the buffer to indicate if it is filled.

A "NO" decision at 20 results in a decision 22 to determine the extent to which the portion of the graphical message has been processed. A "YES" decision at 22 results when the data section has been fully processed. An operation 23 increments the section counter and then operation 14 is executed.

An operation 24 is initiated when the "YES" path is followed from the decision
20. The operation 24 creates storage in the data buffer for measurement and verification options. The operation 24 is also entered from the decision 16 by way of the "YES" path when the last data record has been processed.

An operation 26 makes...
