Abstract

A semiconductor structure and a method for operating the same are provided. The semiconductor structure includes a substrate, a first doped region, a second doped region, a third doped region, a first trench structure and a second gate structure. The first doped region is in the substrate. The first doped region has a first conductivity type. The second doped region is in the first doped region. The second doped region has a second conductivity type opposite to the first conductivity type. The third doped region having the first conductivity type is in the second doped region. The first trench structure has a first gate structure. The first gate structure and the second gate structure are respectively on different sides of the second doped region.
