Abstract:
The present disclosure provides a trench power semiconductor component and a method of manufacturing the same. The trench gate structure of the trench power semiconductor component includes a shielding electrode, a gate electrode disposed above the shielding electrode, and an inter-electrode dielectric layer. Before the formation of the inter-electrode dielectric layer, the step of forming the trench gate structure includes: forming a laminated structure covering the inner wall surface of the cell trench, in which the laminated structure includes a semiconductor material layer and an initial inner dielectric layer covering the semiconductor material layer; forming a heavily-doped semiconductor material in the lower part of the cell trench; and removing a portion of the initial inner dielectric layer located at an upper part of the cell trench to expose an upper half portion of the semiconductor material layer and a top portion of the heavily doped semiconductor material.

Claim (Index 16):
The method according to  claim 10 , further comprising: after the step of forming the trench gate structure, forming a base region and a source region in the epitaxial layer.
