Abstract:
The present invention discloses a high voltage device and a manufacturing method thereof. The high voltage device is formed in a semiconductor substrate, and includes: a gate, a source, a drain, and at least one plug plate electrode. The plug plate electrode is in direct contact with the gate, and is electrically connected to the gate. The plug plate electrode extends downwards from the bottom of the gate to the semiconductor substrate, through a current vertical height of a conductive current when the high voltage is ON. The plug plate electrode is between the source and the drain in a lateral direction. The plug plate electrode includes a dielectric layer and a conductive layer.

Claim (Index 16):
The manufacturing method of  claim 14 , further comprising:\n forming a high voltage well with the first conductive type in the semiconductor substrate, wherein the high voltage well is located beneath the top surface and contacts the top surface in the vertical direction, wherein the source, the drain, the drift region, and at least part of the plug plate electrode are located in the high voltage well, wherein part of the high voltage well is used as the drift region; and forming a body region with the second conductive type in the semiconductor substrate, wherein the body region is located beneath the top surface and contacts the top surface in the vertical direction, wherein the source is located in the body region, wherein part of the body region is used as a channel region.
