    摘要: The present disclosure provides one embodiment of an integrated circuit (IC) method. The method includes receiving an IC design layout having an main feature, the main feature including two corners and an edge spanning between the two corners; performing a feature adjustment to the edge; performing a dissection to the edge such that the edge is divided to include two corner segments and one center segment between the two corner segments; performing a first optical proximity correction (OPC) to the main feature for a center target associated with the center segment; thereafter, performing a second OPC to the main feature for two corner targets associated with the corner segments; and thereafter, performing a third OPC to main feature for the center target, resulting in a modified design layout.

    摘要: A method for performing OPC and evaluating OPC solutions is disclosed. An exemplary method includes receiving a design database corresponding to an IC circuit mask. A first lithography simulation and evaluation is performed on the design database utilizing a first set of performance indexes. A modification is made to the design database based on a result of performing the first lithography simulation and evaluation. A second lithography simulation and evaluation is performed on the design database utilizing a second set of performance indexes to verify the modification. If necessary, the design database is modified again based on a result of the second lithography simulation and evaluation. The modified design database is provided to a mask manufacturer for manufacturing the mask corresponding to the modified design database.
