Abstract:
Provided is a trench gate MOSFET including a substrate of a first conductivity type, an epitaxial layer of the first conductivity type, a first conductive layer of a second conductivity type, a second conductive layer and an interlayer insulating layer. The epitaxial layer is disposed on the substrate and has at least one trench therein. The first conductive layer is disposed in the lower portion of the trench and in physical contact with the epitaxial layer. The second conductive layer is disposed in the upper portion of the trench. The interlayer insulating layer is disposed between the first conductive layer and the second conductive layer.

Claim (Index 1):
A trench gate MOSFET, comprising:\n an epitaxial layer of a first conductivity type, disposed on a substrate of the first conductivity type and having at least one trench; a first conductive layer of a second conductivity type, disposed in a lower portion of the trench and in physical contact with the epitaxial layer; a second conductive layer, disposed in an upper portion of the trench; an interlayer insulating layer, disposed between the first conductive layer and the second conductive layer; and a metal layer disposed over the second conductive layer and electrically connected to the first conductive layer, wherein the metal layer is electrically connected to the first conductive layer through a first contact plug located in the trench in an active area.
