Web24 dec. 2024 · Since next-generation lithography (NGL) is still not mature enough, the industry relies heavily on resolution enhancement techniques (RETs), wherein optical proximity correction (OPC) with 193 nm immersion lithography is dominant in the foreseeable future. However, OPC algorithms are getting more aggressive. … WebOptical 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 integrity of the original design, after …

WebDouble-patterning replaces a very challenging lithography step (with one expensive mask) with two simpler lithography steps (and two less expensive masks). You are trading off the additional cost and time required for a second patterning step for the simplification of the mask design. This concept can be extended to more than two masks. WebComputational lithography uses algorithmic models of the manufacturing process, calibrated with key data from our machines and from test wafers. These models are used to optimize the mask, or blueprint of the desired end result, by intentionally deforming the patterns to compensate for the physical and chemical effects that occur during ...
