Abstract:
In a method of manufacturing a semiconductor device, a first fin structure for an n-channel fin field effect transistor (FinFET) is formed over a substrate. An isolation insulating layer is formed over the substrate such that an upper portion of the first fin structure protrudes from the isolation insulating layer. A gate structure is formed over a part of the upper portion of the first fin structure. A first source/drain (S/D) epitaxial layer is formed over the first fin structure not covered by the gate structure. A cap epitaxial layer is formed over the first S/D epitaxial layer. The first S/D epitaxial layer includes SiP, and the cap epitaxial layer includes SiC with a carbon concentration is in a range from 0.5 atomic % to 5 atomic %.

Claim (Index 12):
A method of manufacturing a semiconductor device including a static random access memory (SRAM) cell, the method comprising:\n forming first fin structures for n-channel fin field effect transistors (FinFETs) and second fin structures for p-channel FinFETs for the SRAM cell over a substrate; forming an isolation insulating layer over the substrate such that upper portions of the first fin structures and upper portions of the second fin structures protrude from the isolation insulating layer; forming first source/drain (S/D) epitaxial layers over the first fin structures; forming cap epitaxial layers over the first S/D epitaxial layers; and forming second S/D epitaxial layers over the second fin structures, wherein: the first S/D epitaxial layers include SiP, the cap epitaxial layers include SiC or SiCP, and during the forming the second S/D epitaxial layer, no cover layer that protects the cap epitaxial layers is disposed on the cap epitaxial layers.
