Abstract :
For emerging deep-subwavelength lithography technologies (65 nm and following) the computation cost and complexities of the conventional resolution enhancement technologies (RET) such as optical proximity correction (OPC) are themselves becoming bottlenecks in the IC manufacturing flow. This has motivated the recent calls for faster and more flexible solutions. In this paper, we present a new algorithm and a general flow which can be used for implementing regional OPC to meet the increasing needs of engineering change order. Using this new method, approximately 80% run-time is saved and the same accuracy maintained as compared to the conventional OPC methods. Several new concepts such as segmentation matching and smooth transition are brought forward to overcome the ripple effects and stitch the Regional OPC result back into the whole layout.
