Semiconductor device and semiconductor device manufacturing method
A semiconductor device includes a semiconductor substrate; a first semiconductor region that includes an extension portion extending in a specific direction at a specific width as viewed along a direction orthogonal to the main surface; a second semiconductor region that is shaped to include a portion running along the extension portion of the first semiconductor region as viewed along the direction orthogonal to the main surface; a field relaxation layer that relaxes a field generated between the first semiconductor region and the second semiconductor region, that is formed on the second semiconductor region side of the main surface, and that is formed by a semiconductor layer; and a conductor that is connected to the second semiconductor region, and that has an end portion on the first conductor region side positioned within the range of the field relaxation layer.
