【摘要】 综合了SU-8胶光刻过程中衍射、反射、折射、吸收率随光刻胶深度的变化及交联显影等各种效应,考虑了折射及吸收系数随时间的变化,建立了SU-8化学放大胶的光刻模型.模拟结果显示,该模型比现有的模拟方法结果更精确,与实验结果符合较好,可以在实际应用中对SU-8光刻胶的二维模拟结果进行有效预测.更多还原

【Abstract】 A new simulation method is proposed which considers diffraction,reflection,refraction,energy loss,absorption coefficient change,post-bake,and development.Compared with previous simulation methods,the present results show good agreement with experimental results.This shows that the simulation accuracy is increased.It is useful for the research of SU-8 phoptoresist deep UV lithography processes and micro-electro-mechanical system design.更多还原
