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 5):
The method for manufacturing the semiconductor device of  claim 1 , wherein a level of a top surface of the fourth dielectric layer is higher than a level of a top surface of the epitaxial layer.
