Abstract:
A library cell is designed, and then the width of the polys is increased, and the polys and contacts are shifted in order to maintain poly-to-poly and contact-to-poly spacing. The method can be used in association with a 45 nm digital library cell. Specifically, a library cell having 40 nm polys is designed, and then the width of each of the polys is increased by 5 nm to 45 nm, and the polys and contacts are shifted in order to maintain poly-to-poly and contact-to-poly spacing. The poly lines and contacts can be shifted by starting at the center and going out radially, or by beginning at the perimeter and moving radially inward. The method can be used with any library cell design which is entirely GDS based, including, for example, 32 nm library cell design.
