Abstract:
1. A method comprising: providing a semiconductor-on-insulator substrate comprised of a top semiconductor layer overlying an insulation layer, where the insulation layer overlies a bottom silicon layer, where the top semiconductor layer has a first thickness, a first width and a first depth, where the top semiconductor layer comprises a first portion and a second portion; removing part of the second portion of the top semiconductor layer to achieve at least one of a second width that is less than the first width, and a second depth that is less than the first depth, where the removed part of the second portion is less than an entirety of the second portion; disposing a first insulator on the first portion of the top semiconductor layer and a second insulator on the second portion of the top semiconductor layer, where a total thickness of the first portion substantially equals a total thickness of the second portion; forming at least one first device that at least partially overlies and is disposed upon the first insulator and the first portion of the top silicon layer; and forming at least one second device that at least partially overlies and is disposed upon the second insulator and the second portion of the top silicon layer.
