Abstract:
Provided is a semiconductor device including: a fin structure on a substrate including a negative channel field-effect transistor (nFET) region and a positive channel field-effect transistor (pFET) region; a gate structure on the fin structure; and a source/drain structure adjacent to the gate structure, wherein the source/drain structure formed in the nFET region is an epitaxial layer including an n-type impurity at a concentration of about 1.8×10 21 /cm 3  or more, includes silicon (Si) and germanium (Ge) on an outer portion of the source/drain structure, and includes Si but not Ge in an inner portion of the source/drain structure, wherein an inclined surface contacting an uppermost surface of the source/drain structure forms an angle of less than about 54.7° with a top surface of the fin structure.

Claim (Index 16):
A semiconductor device comprising:\n a fin structure on a substrate including an nFET region and a pFET region; an element isolating layer between the fin structures; a gate structure on the fin structure; and a source/drain structure adjacent to the gate structure, wherein the source/drain structure formed in the nFET region includes: a top pattern of the fin structure which is a portion of the fin structure protruding over the element isolating layer; and a selective epitaxial growth (SEG) portion formed on a top surface and side surfaces of the top pattern of the fin structure, wherein an angle between an inclined surface portion of an uppermost surface of the SEG portion and the top surface of the top pattern of the fin structure is less than about 54.7\u00b0, and the SEG portion includes Si and Ge on an outer portion of the SEG portion and includes Si but not Ge in an inner portion of the SEG portion.
