    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.

    摘要: 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.
