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 14):
The method of  claim 13 , wherein removing the portion of the first fin structure comprises removing isolation features in the first region to form a third recessed region, wherein removing the portion of the second fin structure comprises removing isolation features in the second region to form a fourth recessed region, and wherein the third recessed region and the fourth recessed region are formed in a space between the first source/drain feature and the second source/drain feature and are separated by an island of the isolation features.
