Optical proximity correction pdf
WebProximity effect refers to features with the same nominal critical dimension (CD) printing differently because of environmental variations. The most typical scenario is shown in Fig. 4.1 (a), which plots the printed dimension of a nominally d Ì =0.4 line as a function of pitch. As the pitch increases separation between adjacent lines widens ... WebThe miniaturization of nodes poses new challenges in semiconductor manufacturing. Optical proximity correction (OPC) is typically performed to satisfy technical requirements through iterative optimization. However, this method is expensive and slow. This study proposes a framework based on patch loss and a generative adversarial network through …
