A semiconductor body has source and drain regions (4 and 5; 4' and 5') spaced apart by a body region (6; 6') and a drain drift region (50; 50') and both meeting the same surface (3a) of the semiconductor body. An insulated gate structure (7; 70'; 700) is provided within a trench (80; 80'; 80'') extending in the semiconductor body. The gate structure has a gate conductive region (70b; 70'b; 70''b) separated from the trench by a dielectric layer (70a; 70'a) such that a conduction channel accommodation portion (60; 60') of the body region extends along at least side walls (80a; 80'a; 80''a) of the trench and between the source (4; 4') and drain drift (50; 50') regions. The trench extends from the body region into the drain drift region (50; 50') and the dielectric layer has, at least on side walls (80a; 80'a; 80''a) of the trench, a greater thickness in the portion of the trench extending into the drain drift region (50; 50') than in the remaining portion of the trench so that an extension (71; 71'; 71''; 710) of the gate conductive region extending within the trench through the drain drift region (50; 50') towards the drain region (5; 5') forms a field plate.

A method for fabricating a high-voltage transistor with an extended drain region comprises forming an epitaxial layer (101) on a substrate (100), the epitaxial layer and the substrate being of a first conductivity type; then etching the epitaxial layer to form a pair of spaced-apart trenches that define first and second sidewall portions of the epitaxial layer, wherein the mesa has a lateral width that is less than 20% of a depth of the trenches. A dielectric layer (102) is formed that partially fills each of the trenches, covering the first and second sidewall portions. The remaining portions of the trenches are then filled with a conductive material to form first and second field plate members (103) that are insulated from the substrate and the epitaxial layer.

Here discussed is a method of fabricating a self-aligned contact in a semiconductor device which includes etching a trench in a core area and partially extending into a termination area of a substrate. A first oxide is grown on the substrate proximate the trench. A polysilicon layer is deposited in the core area and the termination area. The polysilicon layer is selectively etched to form a gate region in the core area portion of the trench. The etching of the polysilicon layer also forms a first portion of a gate interconnect region in the termination area portion of the trench and a second portion in the termination area outside of the trench. According to this method the gate contact opening is formed together with the body/source contact.
