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. This ratio is often called the partial coherence factor, or $${\displaystyle \sigma }$$. … See more As the $${\displaystyle k_{1}}$$ factor has been steadily shrinking over the past technology generations, the anticipated requirement of moving to multiple exposure to generate circuit patterns becomes more real. This approach will affect the … See more Today, OPC is rarely practiced without the use of commercial packages from electronic design automation (EDA) vendors. Advances in algorithms, modeling techniques and the use of large compute farms has enabled the most critical patterning … See more Aberrations in optical projection systems deform wavefronts, or the spectrum or spread of illumination angles, which can affect the depth of … See more In contrast to multiple exposure of the same photoresist film, multiple layer patterning entails repeated photoresist coating, deposition, and etching to pattern the same device … See more • Computational lithography • Phase-shift mask • Inverse lithography See more • Overview of OPC, with diagrams, by Frank Gennari See more Web4 III.
