Abstract:
A method for manufacturing a semiconductor device includes the following steps. An epitaxial layer is formed on a substrate. Then, a body is formed in an upper portion of the epitaxial layer. A first dielectric layer, a second dielectric layer, and a third dielectric layer are sequentially formed on the epitaxial layer. The third dielectric layer forms a second trench, and the second trench is located in the first trench. A shield layer is formed in the second trench. The upper portion of the third dielectric layer is removed, such that the upper portion of the shield layer protrudes from the third dielectric layer. A fourth dielectric layer is formed to cover the upper portion of the shield layer. A gate is formed on the third dielectric layer. A source is formed in the epitaxial layer surrounding the gate.

Claim (Index 6):
A semiconductor device, comprising:\n a substrate; an epitaxial layer disposed on the substrate; a body disposed on an upper portion of the epitaxial layer; a third dielectric layer disposed in a first trench of the epitaxial layer and defining a second trench; a shield layer having an upper portion and a lower portion, wherein the lower portion is located in the second trench, and the upper portion is protruded from the third dielectric layer; a fourth dielectric layer covering the upper portion of the shield layer; a gate disposed in the epitaxial layer and on the third dielectric layer, wherein at least a part of the fourth dielectric layer is disposed between the upper portion of the shield layer and the gate; and a source disposed in the epitaxial layer surrounding the gate.
