Abstract: A semiconductor device includes a substrate including a peripheral region, a first active pattern on the peripheral region, the first active pattern having an upper portion including first semiconductor patterns and second semiconductor patterns, which are alternately stacked, a first gate electrode intersecting the first active pattern, a pair of first source/drain patterns provided at both sides of the first gate electrode, respectively, a first capping layer on the first active pattern, a second capping layer on the first capping layer, and a first gate insulating layer between the second capping layer and the first gate electrode. The first capping layer is between a sidewall of the first active pattern and the second capping layer. A concentration of germanium (Ge) of the first capping layer is greater than a concentration of germanium of the second capping layer.

Abstract: A method includes forming an active pattern on a substrate, the active pattern comprising first semiconductor patterns and second semiconductor patterns, which are alternately stacked, forming a capping pattern on a top surface and a sidewall of the active pattern, performing a deposition process on the capping pattern to form an insulating layer, and forming a sacrificial gate pattern intersecting the active pattern on the insulating layer. The capping pattern has a crystalline structure and is in physical contact with sidewalls of the first semiconductor patterns and sidewalls of the second semiconductor patterns.

Abstract: Disclosed is a semiconductor device. The semiconductor device comprises a fin structure on a substrate, device isolation patterns provided on the substrate and disposed on opposite sides of the fin structure, a gate electrode running across the fin structure and the device isolation patterns, a gate dielectric pattern between the gate electrode and the fin structure and between the gate electrode and the device isolation patterns, and a capping layer between the substrate and the device isolation patterns and between the fin structure and the device isolation patterns. The capping layer has a thickness greater than a thickness of the gate dielectric pattern.
