Abstract: To improve characteristics of a semiconductor device (vertical power MOSFET). A spiral p-type column region having a corner is formed in a peripheral region surrounding a cell region in which a semiconductor element is formed. In an epitaxial layer of the peripheral region surrounding the cell region in which the semiconductor element is formed, a trench spirally surrounding the cell region and having the first and second side faces making up the corner is formed and the trench is filled with the epitaxial layer. By spirally arranging the p-type column region (n-type column region) in such a manner, a drop in a withstand voltage margin due to a hot spot can be avoided. In addition, the continuity of the p-type column region (n-type column region) is maintained. As a result, electric field concentration is alleviated step by step toward the outer periphery and the withstand voltage is therefore increased.
