Abstract
As the semiconductor industry enters 20 nm node and beyond, design restrictions and process complexity lay stress on the development for a new technology node. This paper introduces a hybrid hotspot library building method based on simultaneous optical and geometry analysis, which could help explore design rule optimization and enhance cycle time at early stage for new node development. Lithography simulation results verify the accuracy of this method. This method provide a feasible way to build up a preliminary Design Rule Checking (DRC) library even before process-freezing.
