A Study on SPLAT Based Imaging Algorithm for Off-axis Illumination and Its Implementation
【摘要】 如何提高光刻的分辨率已成为超深亚微米集成电路设计和制造的关键技术。文章简要介绍了分辨率提高技术之一的离轴照明的原理及其构造形式,介绍了部分相干的二维透射系统的仿真程序SPLAT的特点,并用SPLAT实现了一种新的照明结构,为实际开发光学邻近校正(OPC,OpticalProximityCorrection)仿真工具增加了新的功能。
【Abstract】 The principle of offaxis illumination (OAI) and its configurations are presented in the paper And the characteristics of the simulation routine SPLAT, which simulates twodimensional projection printing with partial coherence, are also describedBased on SPLAT, a new configuration of offaxis illumination has been implemented, which was used in developing practical simulation tools for optical proximity correction (OPC) to add new functions
