WebMay 15, 2011 · Optical proximity correction (OPC) is a key step in modern integrated circuit (IC) manufacturing. The quality of model-based OPC (MB-OPC) is directly determined by segment offsets after OPC processing. However, in conventional MB-OPC, the intensity of a control site is adjusted only by the movement of its corresponding segment; this scheme … WebTraditionally, both optical proximity correction (OPC) and sub-resolution assist features (SRAFs) insertion for these repetitive cell-array structures have been dealt by applying manual hand ...

WebA solution for performing an optical proximity correction (OPC) process on a layout by incorporating a critical dimension (CD) correction is provided. A method may include separating the layout into a first portion and a second portion corresponding to the two exposures; creating a model for calculating a CD correction for a site on the first portion, … Optical proximity correction (OPC) is a photolithography enhancement technique commonly used to compensate for image errors due to diffraction or process effects. The need for OPC is seen mainly in the making of semiconductor devices and is due to the limitations of light to maintain the edge placement … See more The degree of coherence of the illumination source is determined by the ratio of its angular extent to the numerical aperture.
