摘要
叙述紫外(i 线)均匀照明光学系统构成原理和光能分布模拟计算设计方法。举例说明用开发的模拟设计软件OPTENG,设计和模拟计算了一个大视场均匀照明光学系统,在照明面积为100m m ×100m m 范围内,照明光能分布不均匀性小于±2 % 。
The optical design methods of uniform illumination for microlithography …construction principle of optical system and simulation calculation of intensity distribution are described. For example, an i line illumination optical system with illumination area 100mm×100mm is calculated by using the simulation software OPTENG and the illumination uniformity of ±2%could be realized.
