    Abstract: A laterally diffused metal-oxide-semiconductor device includes a substrate, a gate dielectric layer, a gate polysilicon layer, a source region, a drain region, a body region, a first drain contact plug, a source polysilicon layer, an insulating layer, and a source metal layer. The source polysilicon layer disposed on the gate dielectric layer above the drain region can serve as a field plate to enhance the breakdown voltage and to increase the drain-to-source capacitance. In addition, the first drain contact plug of the present invention can reduce the drain-to-source on-resistance and the horizontal extension length.

    Abstract: A power semiconductor device having low gate input resistance and a manufacturing method thereof are provided. The power semiconductor device includes a substrate, at least a trench transistor, a conductive layer, a metal contact plug, an insulating layer, an interlayer dielectric, a gate metal layer, and a source metal layer. The metal contact plug can serve as a buried gate metal bus line, and the metal contact plug can pass under the source metal layer and keeps the area of the source metal layer complete. Accordingly, the present invention can provide a lower gate input resistance without dividing the source metal layer, so the source metal layer can have a larger and complete area for the following packaging and bonding process.
