发明名称 SEMICONDUCTOR DEVICE HAVING A SUPER JUNCTION STRUCTURE AND METHOD OF MANUFACTURING THE SAME
摘要 A semiconductor device having a super junction and a method of manufacturing the semiconductor device capable of obtaining a high breakdown voltage are provided, whereby charge balance of the super junction is further accurately controlled in the semiconductor device that is implemented by an N-type pillar and a P-type pillar. The semiconductor device includes a semiconductor substrate; and a blocking layer including a first conductive type pillar and a second conductive type pillar that extend in a vertical direction on the semiconductor substrate and that are alternately arrayed in a horizontal direction, wherein, in the blocking layer, a density profile of a first conductive type dopant may be uniform in the horizontal direction, and the density profile of the first conductive type dopant may vary in the vertical direction.
