Abstract:
A method for fabricating a semiconductor structure includes providing a substrate. The method further includes implanting the substrate to form a high-voltage well region having a first conductivity type. The method further includes forming a pair of drain drift regions in the high-voltage well region. The pair of drain drift regions are on the front side of the substrate, and the pair of drain drift regions have a second conductivity type opposite to the first conductivity type. The method further includes forming a gate electrode embedded in the high-voltage well region. The gate electrode is positioned between the pair of drain drift regions and laterally spaced apart from the pair of drain drift regions.

Claim (Index 1):
A method for fabricating a semiconductor structure, comprising:\n providing a substrate; implanting the substrate to form a high-voltage well (HVW) region having a first conductivity type; forming a pair of drain drift regions in the high-voltage well region, wherein the pair of drain drift regions are on a front side of the substrate, and the pair of drain drift regions have a second conductivity type opposite to the first conductivity type; etching the substrate between the pair of drain drift regions to form a gate trench, wherein the gate trench has a bottom and sidewalls connecting to the bottom, and the bottom of the gate trench is laterally spaced apart from the pair of drain drift regions; and forming a gate electrode embedded in the high-voltage well region, wherein the gate electrode is positioned between the pair of drain drift regions and laterally spaced apart from the pair of drain drift regions.
