Abstract:
An approach that provides electrically driven optical proximity correction is described. In one embodiment, there is a method for performing an electrically driven optical proximity correction. In this embodiment, an integrated circuit mask layout representative of a plurality of layered shapes each defined by features and edges is received. A lithography simulation is run on the mask layout. An electrical characteristic is extracted from the output of the lithography simulation for each layer of the mask layout. A determination as to whether the extracted electrical characteristic is in conformance with a target electrical characteristic is made. Edges of the plurality of layered shapes in the mask layout are adjusted in response to determining that the extracted electrical characteristic for a layer in the mask layout fails to conform with the target electrical characteristic.
