Abstract

A method includes forming a semiconductor capping layer over a first fin in a first region of a substrate, forming a dielectric layer over the semiconductor capping layer, and forming an insulation material over the dielectric layer, an upper surface of the insulation material extending further away from the substrate than an upper surface of the first fin. The method further includes recessing the insulation material to expose a top portion of the first fin, and forming a gate structure over the top portion of the first fin.
