Future challenges in computational lithography
To the degree that the modeling is inaccurate, the edges on the wafer will end up in the wrong locations. Lithographers tell us that optical proximity correction (OPC) errors and mask errors are their two largest error sources. OPC errors, however, have two components: modeling error and numerical e...

Summary: | To the degree that the modeling is inaccurate, the edges on the wafer will end up in the wrong locations. Lithographers tell us that optical proximity correction (OPC) errors and mask errors are their two largest error sources. OPC errors, however, have two components: modeling error and numerical error associated with prescribing the OPC. |
