WebSep 4, 2024 · Mask optimization has been a critical problem in the VLSI design flow due to the mismatch between the lithography system and the continuously shrinking feature sizes. Optical proximity correction (OPC) is one of the prevailing resolution enhancement techniques (RETs) that can significantly improve mask printability. However, in advanced … WebProteus ILT uses inverse imaging technology to resolve the most challenging optical proximity effects encountered on dense designs at leading technology nodes. Increasing design density due to semiconductor technology scaling provides little room for conventional segment-based OPC methodologies resulting in sub-optimal process …

WebOptical Proximity Correction (OPC) OPC is a technique used to compensate for image distortions that occur during sub-wavelength lithography: printing structures smaller than … WebDescription. Optical proximity correction (OPC) is often associated with a photomask. The photomask is produced in a photomask facility. In the flow, a chipmaker designs an IC, which is then translated into a file format. Then, a photomask is developed based on that format. A photomask is a master template for a given IC design.
WebPROBLEM TO BE SOLVED: To reduce the calculation time required for optical proximity effect correction and to improve pattern precision. SOLUTION: The optical proximity effect correction method comprises steps of: setting up a point of correction on a side of a design pattern; seeking a one-dimensional layout existing within the range of the optical …
