A first gate structure is formed over a first region of the semiconductor layer, and a second gate structure is over a second region of the semiconductor layer. A first insulating layer is formed over the first and second regions. The first insulating layer can function as a mask during an etch of the semiconductor layer and can be removed selective to the isolation regions and the sidewall spacers. The first insulating layer is removed from over the first region to leave a remaining portion of the first insulating layer over the second region. The semiconductor layer is recessed in the first region adjacent to the first gate to form recesses. A semiconductor material is epitaxially grown in the recesses.
