Photolithography-tool-vendor Sigma-C contends that your OPC (optical-proximity-corrected) design may not be correct at all. The Munich-based vendor has expanded into the design-for-manufacturing tool ...
SANTA CLARA, Calif. — Optical proximity correction (OPC) can take days or weeks for 65 nm ICs, and the problem will only get worse at 45 nm. Hoping to head off a computational nightmare, Mentor ...
As the technology advances, OPC run time turns to be a big concern, and a great deal of our effort is directed toward speeding up the litho operations. In addition, the OPC simulation consistency ...
