Abstract
A semiconductor device includes a gate electrode formed on a sidewall of a structure extending from a semiconductor substrate. A junction region is form in the structure to a first depth from a top of the structure and formed to overlap the gate electrode. A protection layer is formed between an outer wall of the structure and the gate electrode to a second depth less than the first depth from the top of the structure.
