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 6):
The trench power semiconductor component according to  claim 3 , wherein the trench gate structure further includes an inner insulating layer covering an upper inner surface of the outer insulating layer, the inner insulating layer is connected to the interlayer, and the gate electrode is insulated from the epitaxial layer by the outer insulating layer together with the inner insulating layer.
