  • Patent number: 11107735
    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.
