摘要:
A method of fabricating a semiconductor device includes forming gate structures on PMOS and NMOS transistor regions of the semiconductor substrate, forming epitaxial blocking layers on source/drain regions of PMOS and NMOS transistor regions using a nitridation process, then selectively removing one of the epitaxial blocking layers, and using a SEG process to form an epitaxial layer on respective source/drain regions while shielding the other source/drain regions with a remaining epitaxial blocking layer.

A method of manufacturing a semiconductor device can uniformly form a metal gate irrespective of gate pattern density. The method includes forming an interlayer dielectric layer having a trench on a substrate, forming a metal layer having first, second and third sections extending along the sides of the trench, the bottom of the trench and on the interlayer dielectric layer, respectively, forming a sacrificial layer pattern exposing an upper part of the first section of the metal layer, forming a spacer pattern on the exposed part of the first section of the metal layer, and forming a first gate metal layer by etching the first section of the metal layer using the sacrificial layer pattern and the spacer pattern as masks.

摘要:
Provided are a semiconductor device and a method of fabricating the same. The semiconductor device may include a substrate with an active pattern, a gate electrode provided at the active pattern, and a gate capping structure disposed above the gate electrode. The gate capping structure may include two or more gate capping patterns with different properties from each other, and the use of the gate capping structure makes it possible to form contact plugs in a self-aligned manner and improve operational speed and characteristics of the semiconductor device.
