Patent ID: 10529849

Abstract:
A high-voltage semiconductor device is disclosed. The high-voltage semiconductor device includes a gate structure on a substrate structure. A drain doped region and a source doped region are located close to opposite sides of the gate structure. The source doped region, the gate structure and the drain doped region are located close to a top surface of the substrate structure. A super junction doped structure is located close to the drain doped region. The super junction doped structure includes a plurality of first conductive type doped sub-regions extending along a first direction and arranged along a second direction. A plurality of second conductive type doped sub-regions extends along the first direction and is arranged staggered with the first conductive type doped sub-regions. The widths of the first conductive type doped sub-regions and the second conductive type doped sub-regions along the second direction decrease linearly along the second direction.
