Claim:
1. A semiconductor device, comprising: at least one active fin protruding from a substrate; a first gate electrode crossing the active fin; a first impurity region formed on the active fin at a first side of the first gate electrode, at least a portion of the first impurity region being formed in a first epitaxial layer portion on the active fin; and a second impurity region formed on the active fin at a second side of the first gate electrode, the second impurity region having a greater width in the longitudinal direction of the active fin than the first impurity region, the second impurity region including a first portion and a second portion, the first portion being formed in a second epitaxial layer portion, and the second portion not being formed in an epitaxial layer, wherein the upper surfaces of the first portion and the second portion are substantially coplanar.
