LSI circuits adaptable for custom design methods.

摘要

A standardized cell layout for LSI circuits having a first and second metal overlay pattern (16,18; 260-265) above a predetermined generalized logic circuit pattern, where the first metal overlay includes a generally parallel set of conductors having conductive contact with underlying circuits at a plurality of possible contact points, and the second metal overlay is insulated from the first metal overlay, the second metal overlay having a plurality of orthogonal conductors relative to the first metal overlay, to permit selective laser cutting of first metal conductor segments at positions intermediate second metal conductors, and to permit laser welding of first and second metal conductors at respective intersections of same.
