    • PURPOSE: A DMOS(Double Diffused MOSFET(Metal Oxide Semiconductor Field Effect Transistor)) and a method for manufacturing the DMOS transistor are provided to have stable element characteristics by self-aligning a body region-source-drain, through reducing pinch resistance(Rb) of the body region without adding a mask. CONSTITUTION: A DMOS(Double Diffused MOSFET(Metal Oxide Semiconductor Field Effect Transistor)) comprises a first conductive semiconductor substrate, a gate electrode(44)/a conductive layer pattern(45), a second conductive semiconductor region, a body region(48), a second conductive source, and a doping region. The gate electrode(44) and the conductive layer pattern(45) are formed by inserting a gate insulating layer on the semiconductor substrate. The second conductive semiconductor region is formed in the semiconductor substrate. The body region is formed in the semiconductor region, and a first conductive dopant is doped with high concentration therein. The second conductive source is formed in the body region(48). The doping region(36) is formed to neighbor the source in the body region.
