Abstract
A method for forming a semiconductor device includes blocking a first region of a wafer and forming a plurality of fins in a second region of the wafer. A protective conformal mask layer is deposited over the plurality of fins in the second region, the second region is blocked, and a plurality of fins are formed in the first region of the wafer using a variety of wet and/or dry etching procedures. The protective conformal mask layer protects the plurality of fins in the second region from the variety of wet and/or dry etching procedures that are used to form the plurality of fins in the first region.
