WebJan 1, 1984 · This chapter describes the process of patterning by ion-beam etching. Also called as milling, Ion-beam etching is the slow erosion of a surface because of the bombardment by a stream of high-energy ions. The process is entirely mechanical, being one of momentum transfer between the impinging ions and the surface atoms by which … Web3.1.2 Effects of Topography on the Visibility The topography profile on the wafer affects the visibility of local points on the profile. Certain parts of the profile may cast shadows on other parts of the profile (cf. Figure 3.1) and thus reduce the visibility to various flux components.In deposition this plays a very important role in filling contacts with metal, … nt bnp to bnp
