    Abstract: A semiconductor device having a super junction structure includes a substrate, an epitaxial layer of a first conductivity type, a first trench, a first doped region of a second conductivity type opposite to the first conductivity type, a second trench and a second doped region of the first conductivity type. The epitaxial layer of the first conductivity type is over the substrate. The first trench is in the epitaxial layer. The first doped region of the second conductivity type is in the epitaxial layer and surrounds the first trench. The second trench is in the epitaxial layer and separated from the first trench. The second doped region of the first conductivity type is in the epitaxial layer and surrounds the second trench. The second doped region has a dopant concentration greater than a dopant concentration of the epitaxial layer. A method for manufacturing the semiconductor device is also provided.
