LAYOUT EDITOR FOR SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a layout editor which is difficult to make correction errors in elimination working of a layout diagram in a mask layout design for a semiconductor integrated circuit. SOLUTION: A storage device 2 stores layout data 20, elimination instruction layout data 21 and display layout data 22. The data 20 is generated/edited by using a data editing means 11 of a data processor 1. When elimination is performed on the layout data, the data 21 is generated/edited by using the means 11. When the data 21 is generated, a diagram logic operating means 10 subtracts the data 21 from the data 20 and updates the data 22. Then, a displaying means 12 shows the updated display layout data on a display device 5.
