    摘要: A method to compensate optical proximity correction adapted for a photolithography process includes providing an integrated circuit (IC) layout. The IC layout includes active regions, a shallow trench isolation (STI) region and ion implant regions overlapped with a part of the STI region and at least a part of the active regions. Subsequently, at least a photoresist line width compensation region disposed in the STI region is acquired in a photoresist covering region outside the ion implant regions according to the IC layout. Afterwards, the IC layout is corrected according to a width of the photoresist line width compensation region, a length of a side of the active region facing a side of the photoresist line width compensation region and a distance from the side of the photoresist line width compensation region to the active region facing the side. Then, the corrected IC layout is transferred to a photomask.

    摘要: A method for correcting a photomask pattern is provided. The correcting method performs a verification of a focus-exposure matrix (FEM) and an overlay variation on a layout area having contact holes or vias in a layout pattern so as to generate a hint information. The layout pattern of the photomask is corrected according to the hint information to prevent the contact holes or vias from being exposed in arrangement to corresponding metal layer, poly layer, or diffusion layer.
