    Abstract: A method of fabricating a semiconductor device includes forming an interlayer insulating structure on a substrate, forming a contact hole that penetrates the interlayer insulating structure to expose the substrate, forming an amorphous silicon layer including a first portion and a second portion, the first portion covering a top surface of the substrate exposed by the contact hole, the second portion covering a sidewall of the contact hole, providing hydrogen atoms into the amorphous silicon layer, and crystallizing the first portion using the substrate as a seed.

    Abstract: Semiconductor devices are provided including a first trench in a semiconductor substrate; a first insulating film in the first trench; a first conductive film on the first insulating film, the first conductive film having upper and lower portions and filling at least a portion of the first trench; and a first work function adjustment film having first and second portions, a first lower work function adjustment film portion and a first upper work function adjustment portion. The first lower work function adjustment film portion overlaps the lower portion of the first conductive film and the first upper work function adjustment film portion overlaps the upper portion of the first conductive film between the first insulating film and the first conductive film.
