Webknown as the OPE (optical proximity effect). As a way to avoid OPE, a technique known as OPC (optical proximity correction), which superimposes a correction pattern on the master pattern, is applied. Regarding the refined processes of recent years, the OPC pattern has become more important and more complicated. Accordingly, upon controlling the ... 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.
