Some SRAFs generated... 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 in algorithms, modeling … 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 focus. While the use of OPC can offer … 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 layer. This gives an opportunity to use looser design rules to pattern the same … See more • Computational lithography • Phase-shift mask • Inverse lithography See more
WebModel-based Mask Process Correction (MB-MPC) is one of the key tools used to improve photomask Critical Dimension (CD) uniformity and provide high fidelity, and increase patterning stability of resolution limited features, such as assist features (SRAFs) at today's leading-edge nodes. 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.
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, … WebThe proximity effect correction method has been intro-duced to adjust the unintended optical interaction between field structures, and enhance pattern quality by utilizing dose correction combined with assist features for the original target pattern image, for good pattern fidelity and fabrication effi-ciency [29–36].
