摘要:
Methods of manufacturing a semiconductor device include forming a gate insulation layer including a high-k dielectric material on a substrate that is divided into a first region and a second region; forming a diffusion barrier layer including a first metal on a second portion of the gate insulation layer in the second region; forming a diffusion layer on the gate insulation layer and the diffusion barrier layer; and diffusing an element of the diffusion layer into a first portion of the gate insulation layer in the first region.
摘要:
In a method of manufacturing a semiconductor device, a gate insulation layer is formed on a substrate including a first channel of a first conductive type and a second channel of a second conductive type different from the first conductive type. A first conductive layer including a first metal is formed on the gate insulation layer, and a second conductive layer including a second metal different from the first metal is formed on the first conductive layer formed over the second channel. The second conductive layer is partially removed by a wet etching process to form a second conductive layer pattern over the second channel.
摘要:
A semiconductor device includes a semiconductor substrate including an NMOS region and a PMOS region, a gate insulating layer formed on the semiconductor substrate, an NMOS gate formed on the gate insulating layer of the NMOS region, and a PMOS gate formed on the gate insulating layer of the PMOS region. Any one of the NMOS gate and the PMOS gate includes a one-layered conductive layer pattern, and another of the NMOS gate and the PMOS gate includes a three-layered conductive layer pattern.
