    摘要: The present invention discloses a high voltage metal oxide semiconductor (HVMOS) device and a method for making same. The high voltage metal oxide semiconductor device comprises: a substrate; a gate structure on the substrate; a well in the substrate, the well defining a device region from top view; a first drift region in the well; a source in the well; a drain in the first drift region, the drain being separated from the gate structure by a part of the first drift region; and a P-type dopant region not covering all the device region, wherein the P-type dopant region is formed by implanting a P-type dopant for enhancing the breakdown voltage of the HVMOS device (for N-type HVMOS device) or reducing the ON resistance of the HVMOS device (for P-type HVMOS device).
