Abstract:
A HV MOS transistor device is provided. The HV MOS transistor device includes a substrate comprising at least an insulating region formed thereon, a gate positioned on the substrate and covering a portion of the insulating region, a drain region and a source region formed at respective sides of the gate in the substrate, and a first implant region formed under the insulating region. The substrate comprises a first conductivity type, the drain, the source, and the first implant region comprise a second conductivity type, and the first conductivity type and the second conductivity type are complementary to each other.
