Abstract
A power semiconductor device may include a first conductivity type semiconductor substrate, a super-junction portion disposed on the first conductivity type semiconductor substrate and including a first conductivity type pillar and a second conductivity type pillar arranged in an alternating manner, and a three-dimensional (3D) gate portion disposed on the first conductivity type pillar. The 3D gate portion is disposed on the first conductivity type pillar to reduce the widths of the first and second conductivity type pillars, thereby effectively reducing a device size.
