Abstract
A semiconductor device layout structure is provided. The semiconductor device layout structure includes an active region having a first conductivity type over a semiconductor substrate. The active region is provided with semiconductor devices formed thereon. A first super junction layout unit in the active region includes a first trench. A first doped region having a first conductivity type is formed surrounding the first trench. A second trench is formed surrounding the first doped region. A second doped region having a second conductivity type is formed surrounding the second trench. The first trench is laterally separated from the second trench through the first doped region and the second doped region in a plan view.
