 · • The selectivity of an etch is the ratio of the etch rate for the material it is desired to remove versus the etch rate for some other material that it should not remove: • Example: For 10:1 BOE etching a Si wafer surface that contains SiO 2, aluminum metalization, and Si 3 N 4 spacers: – 10:1 BOE SEL for SiO 2 / aluminum = ~ 15:1

7.1 Locate the grinding wheel equipped with the 60 grit sandpaper. Start with the grit with the smallest number, as this is the coarsest which will do most of the grinding away of the top oxide layer of the metal revealing the shiny surface. You will gradually work your way through finer and finer grit. 7.2. Start the machine as prompted by the ...
