Semiconductor structure having a high voltage well region
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.
