Abstract

Bell-Northern Research has developed a program for design rule checking of integrated circuit masks, based on a one-dimensional scanning technique using a novel data coding scheme for efficient processing of large volumes of geometric data. The rule checking concept is very simple and the program is small and easily implemented. The technique is also extremely economical, costing less than $100 to apply 25 design checks to a high density 5200 µm square silicon gate n-channel mask. CPU time varies approximately as the power 1.2 of the amount of data in the mask.
