Abstract:
Methods of forming semiconductor devices are provided. A method of forming a semiconductor device includes forming an insulating layer that includes a trench therein. The method includes forming a high-k layer in the trench. Moreover, the method includes forming a metal layer on the high-k layer, then performing a first heat treatment at a first temperature, and performing a second heat treatment at a second temperature that is higher than the first temperature.
