Title: Layout method and layout apparatus for patterns of semiconductor device
Inventor: YONETANI HIDEKI
IPC: H01L21/82
Filed: 2000-11-09
Abstract: PROBLEM TO BE SOLVED: To provide a layout method and layout apparatus for obtaining the constitution of a dummy pattern group whereby dummy patterns can be inserted efficiently into the layout of actual patterns while suppressing the increase of the data amount required therefor. SOLUTION: In the layout method, there are calculated the regions which can dispose dummy patterns in themselves and become irregular error regions when inserting no dummy pattern into them, and then, first dummy patterns are inserted into them. Subsequently, for the left irregular error places unremoved by the insertions of the first dummy patterns, the insertions of second dummy patterns smaller than the first ones are tried. As a result, there is obtained the layout of a dummy pattern group wherein the insertion of the dummy patterns is performed effectively while suppressing increase of the data amount required therefor.
