Webmethods of optical proximity correction (OPC) as shown in Figure 2 [1][4][12]. In semiconductor manufacturing, OPC is a common way used in optical lithography to improve the imaging variation problem and improve layout mask quality [5]. Figure 2. Conceptual approach to OPC. The two main classifications of OPC are rule-based and model-based.
WebRecurrent neural network (RNN) is employed as a machine learning model for fast optical proximity correction (OPC). RNN consists of a number of neural network instances which are serially connected, with each instance in charge of one segment. RNN thus allows some localized segments to be corrected together in one execution, which offers higher … 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 …
