Abstract:
A method includes providing a semiconductor substrate having first and second regions that are doped with first and second dopants respectively. The first and second dopants are of opposite types. The method further includes epitaxially growing a first semiconductor layer that is doped with a third dopant. The first and third dopants are of opposite types. The method further includes depositing a dielectric hard mask (HM) layer over the first semiconductor layer; patterning the dielectric HM layer to have an opening over the first region; extending the opening towards the semiconductor substrate; and epitaxially growing a second semiconductor layer in the opening. The second semiconductor layer is doped with a fourth dopant. The first and fourth dopants are of a same type. The method further includes removing the dielectric HM layer; and performing a first CMP process to planarize both the first and second semiconductor layers.

Claim (Index 6):
The method of  claim 1 , further comprising recessing the first region of the substrate prior to forming the second semiconductor layer on the first region of the substrate.
