主要描述了紫外准分子激光刻蚀聚酰亚胺 (polyimide ,PI)制作微图案实验。通过这种刻蚀方法 ,成功地在PI上制作了微米量级线宽和亚微米量级深度的图案
The microphotograph experiment of UV excimer laser etching polyimide (PI) was mainly described. By this etching method, a pattern of micron-sized line widths and submicron-order depths has been successfully fabricated on PI
