STRUCTURE DESIGN GENERATION FOR FIXING METAL TIP-TO-TIP ACROSS CELL BOUNDARY

摘要

A method for semiconductor structure design includes performing, by a processor, error processing of an initial design file layout. The processor further detects a tip-to-tip (T2T) structure design violation at a design cell boundary for a metal layer above (Ma) a via (Vx) at a tip of the Ma for the initial design file layout for a semiconductor structure based on a library of pattern rules. Upon detection of the T2T structure design violation, the processor retargets the Vx for generating a resulting design file layout of the semiconductor structure.
