中文摘要：
接近式光刻中一般采用柯勒照明系统，并采用蝇眼透镜形成多点光源均匀掩模面的光场分布．利用基尔霍夫衍射理论及多点光源的衍射光场非相干叠加方法，对光刻胶表面的衍射光场进行了快速计算机模拟，并与霍普金斯理论计算结果进行了分析比较．结果表明采用基尔霍夫衍射理论及多点光源的衍射光场非相干叠加的模型不仅快速而且也可以比较准确地模拟接近式光刻的衍射光场分布．
英文摘要：
Kohler illumination was used in proximity lithography, and a fly＇s eye lens was adopted to form multi-point source in order to uniform the light intensity on the mask plane. A fast computer simulation of diffraction intensity on the photoresist surface was performed based on Kirchhoff＇s diffraction theory and the incoherent super-impose of multi-point source diffraction intensity. Compared with the results based on Hopkins theory, the fast computer simulation results show that the diffraction intensity in proximity lithography may be simulated more rapidly and precisely with the new model.
