摘要
叙述了i-line光刻高均匀照明系统的均匀照明原理,以及其具有特殊面形(非球面)、特殊结构(非共轴)、超光学表面(由多个非共轴光学表面组成)的光学系统的光能分布计算模拟的原理、方法。作为例子,用所编写的程序计算模拟了我们近来设计的一曝光系统几个重要光学表面上具有权重的点列图和光能分布曲线。
The principle of i line uniform illumination optical system for photolithography,and the principle,method used in calculation and simulation of the intensity distribution of the special surface shape(aspherics),special structure(non coaxis) and super optical surface(including multiple non coaxial optical surface) are described in the paper. As an example,the sopt diagram with weighting and the light intensity curve on the several important optical surfaces designed recently are simulated by the program compiled by ourselves.
