Abstract:
A process for forming silicon material having a boss section and a flexure section, said boss section thicker than said flexure section, said process comprising the steps of:providing a substrate of one type doped silicon material; diffusing another type dopant material into said substrate so as to provide another type doped silicon material at a depth (x-y) from a surface of said one type doped silicon material, said diffusing located only in the regions of the boss section, where x is the boss section thickness and y is the flexure section thickness;epitaxially growing a layer of said another type doped silicon on said substrate to said flexure section thickness y over the surface of said substrate; andetching away one type doped silicon material with a one type doped silicon etchant leaving said boss section having a thickness x and said flexure section having a thickness y.
