Abstract:
A method of fabricating a fin-like field effect transistor (FinFET) device includes providing a semiconductor substrate having a region for forming p-type metal-oxide-semiconductor (PMOS) devices and a region for forming n-type metal-oxide-semiconductor (PMOS) devices, forming fin structures in both regions of the substrate separated by isolation features, first forming source/drain (S/D) features in the PMOS region, and subsequently forming S/D features in the NMOS region. First forming the PMOS S/D features and then forming the NMOS S/D features results in a greater extent of loss of isolation features in the PMOS region than in the NMOS region.

Claim (Index 7):
The method of  claim 5 , wherein recessing the first fin structure and the recessing of the second fin structure forms a first recessed region and a second recessed region in the isolation features, respectively, the first recessed region and the second recessed region being formed between the first fin structure and the second fin structure, and wherein a lateral distance of the first recessed region is greater than a lateral distance of the second recessed region.
