Abstract:
The present disclosure provides a trench power semiconductor component and a method of making the same. The trench power semiconductor component includes a substrate, an epitaxial layer, and a trench gate structure. The epitaxial layer is disposed on the substrate, the epitaxial layer having at least one trench formed therein. The trench gate structure is located in the at least one trench. The trench gate structure includes a bottom insulating layer covering a lower inner wall of the at least one trench, a shielding electrode located in the lower half part of the at least one trench, a gate electrode disposed on the shielding electrode, an inter-electrode dielectric layer disposed between the gate electrode and the shielding electrode, an upper insulating layer covering an upper inner wall of the at least one trench, and a protection structure including a first wall portion and a second side wall portion.

Claim (Index 2):
The trench power semiconductor component according to  claim 1 , wherein the first wall portion of the trench extends from an opening end of the trench into the first slit, and the second side wall portion of the trench extends from the opening end of the trench into the second slit.
