Patent ID: 7284231

Claim:
A method for improving manufacturability of a semiconductor device layout design comprising: performing at least one interlayer space check and one intralayer space check on more than one of multiple interacting layers of a target design; and modifying the target design to create an altered target design database in response to the results of the space checks, wherein modifying the target design includes a first movement of a group of at least one edge on a feature within the target design to decrease a risk of one of feature widths, feature enclosure and feature spaces being patterned smaller than designed, and wherein modifying the target design further includes a second movement of a group of at least one edge on a feature to decrease a risk of one of feature widths, feature enclosure and feature spaces being patterned smaller than designed in response to the first movement of edges, wherein the first movement includes moving predetermined feature edges by moving edges of routing poly outward and interacting routing poly inward.
