Abstract

See full text

Embodiments of the present disclosure include methods, program products, and systems for adjusting an integrated circuit (IC) layout for optical proximity correction (OPC). Methods according to the disclosure can include: defining a target region of the IC design layout, the target region having a plurality of patterns including a first pattern positioned adjacent to a second pattern, wherein an OPC modeling rule of the IC design layout prohibits the first pattern from being adjusted, and wherein the second pattern does not reduce a printability metric of the first pattern; adjusting the design of the second pattern to reduce at least one printing error in the first pattern, wherein a functionality of the second pattern in the IC design layout is unchanged after the adjusting; and implementing OPC on the IC design layout including the target region with the adjusted second pattern therein.
