摘要

Linear ion source (LIS) was investigated for the surface etching process, especially the surface of cold rolled steel (CRS). In this study, Si substrate was used to substrate because rough surface of CRS is difficult to measure the etching depth. The LIS was operated in a collimated beam discharge with high energy Ar ions extraction. The etching behaviors showed strong dependences on the incident angle of ion beam. The maximum Si etching rate was obtained at 60°, which is similar to the trend of sputtering yield as a function of incident angle. The maximum ion current density was 389 μA/cm~(-2) at the distance between LIS and substrate of 100 mm. And the maximum etching rate was 3.4 nm/s at the distance of 60 mm
