METHOD FOR COMPENSATING FOR VARIATIONS IN STRUCTURES OF AN INTEGRATED CIRCUIT

METHOD FOR COMPENSATING FOR VARIATIONS IN STRUCTURES OF AN INTEGRATED CIRCUIT

A method of for compensating for variations in structures of an integrated circuit. The method includes (a) selecting a mask design shape and selecting a region of the mask design shape; (b) applying a model-based optical proximity correction to all of the mask design shape; and after (b), (c) apply...

Zusammenfassung:A method of for compensating for variations in structures of an integrated circuit. The method includes (a) selecting a mask design shape and selecting a region of the mask design shape; (b) applying a model-based optical proximity correction to all of the mask design shape; and after (b), (c) applying a rules-based optical proximity correction to the selected region of the mask design shape.
