| 1. | The feasibility that kaufman ion source is applied in reactive ion beam etching is discussed . etching characteristics of materials , including pr , cr , quartz , are investigated . the etch rate and mechanisms of such materials are measured and analyzed as a function of ion energy , ion beam density and ion incidence angle in pure ar and chf3 , respectively . the etch rate has shown a square root dependence on variation versus
深入研究了光刻胶、铬薄膜、石英等光学材料离子束刻蚀特性,分别以ar气和chf3为工作气体,研究光刻胶、铬薄膜、石英等的刻蚀速率随离子能量,束流密度和离子入射角度的变化关系,得到刻蚀速率与影响因素的拟合方程,为掩模的制作工艺路线提供了实验依据和理论指导。 |
