Abstract

An optical proximity correction (OPC) system and methods thereof are provided. The example OPC system may include an integrated circuit (IC) layout generation unit generating an IC layout, a database unit storing a first plurality of OPC models, each of the first plurality of OPC models associated with one of a plurality of target specific characteristics and a mask layout generation unit including a model selector selecting a second plurality of OPC models based on a comparison between the target specific characteristics associated with the plurality of OPC models and the generated IC layout, the mask layout generation unit generating a mask layout based on the IC layout and the selected second plurality of OPC models. A first example method may include storing a first plurality OPC models, each of the first plurality of OPC models associated with one of a plurality of target specific characteristics, generating an IC layout, selecting a second plurality of OPC models based on a comparison between the target specific characteristics associated with the first plurality of OPC models and the generated IC layout and generating a mask layout based on the generated IC layout and the selected second plurality of OPC models. A second example method may include applying a first OPC model to a first portion of a generated integrated circuit (IC) layout, applying a second OPC model to a second portion of the generated IC layout and generating a mask layout based on the generated IC layout after the application of the first and second OPC models.
