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 1):
A high voltage device formed in a semiconductor substrate, wherein the semiconductor substrate has a top surface and a bottom surface opposite to the top surface in a vertical direction, the high voltage device comprising:\n a gate, which is formed on and contacts the top surface of the semiconductor substrate, and is configured to operably control the high voltage device to be ON or OFF according to a gate voltage; a source with a first conductive type, which is formed in the semiconductor substrate, and is located beneath the top surface and contacts the top surface in the vertical direction, and is located adjacent to a first side of the gate in a lateral direction; a drain with the first conductive type, which is formed in the semiconductor substrate, and is located beneath the top surface and contacts the top surface in the vertical direction, and is located outside a second side opposite to the first side of the gate in the lateral direction, wherein the drain is separated from the gate by a drift region in the lateral direction; and at least one plug plate electrode, which contacts a bottom of the gate and is electrically connected to the gate, and is located between the source and the drain in the lateral direction, the plug plate electrode extending downward from the bottom of the gate into the semiconductor substrate, wherein the downward extension extends by a vertical length which is longer than a current vertical height of a conductive current when the high voltage device is ON, wherein the current vertical height is a length of a vertical distribution of the conductive current; wherein the plug plate electrode includes a dielectric layer and a conductive layer, wherein the dielectric layer contacts the top surface, and the conductive layer is electrically connected to the gate.
