Abstract
A semiconductor device includes an epitaxial layer on a substrate, a first body region and a first trench gate structure in the epitaxial layer, a first planar gate and a first source electrode on the epitaxial layer, a first source region in the first body region, and a drain electrode under the substrate. The first trench gate structure is extended along a first direction and adjacent to the first body region. The first planar gate is extended along a second direction and at least partially located directly above the first body region. There is a non-zero included angle between the second direction and the first direction. The first source electrode is extended downward into the first body region. The first source region is at least partially adjacent to the first source electrode.
