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 … See more Today, OPC is rarely practiced without the use of commercial packages from electronic design automation (EDA) vendors. Advances … See more • Overview of OPC, with diagrams, by Frank Gennari 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, … See more • Computational lithography • Phase-shift mask • Inverse lithography See more WebIn this thesis, we first look at the Optical Proximity Correction (OPC) problem and define the goals, constraints, and techniques available. Then, a practical and general OPC framework is built up using concepts from linear systems, control theory, and computational geometry. A simulation-based, or model-based, OPC algorithm is developed which ... hkust open day 2022WebWe describe a method for optical proximity correction (OPC) based on the principle of aerial image matching.
