摘要: Provided are a semiconductor device and a method of fabricating the same. The method includes: forming a trench in a semiconductor substrate of a first conductive type; forming a trench dopant containing layer including a dopant of a second conductive type on a sidewall and a bottom surface of the trench; forming a doping region by diffusing the dopant in the trench dopant containing layer into the semiconductor substrate; and removing the trench dopant containing layer.
