Abstract:
A trench-type metal-oxide-semiconductor field-effect transistor (MOSFET) device and a fabrication method are disclosed. A semiconductor substrate of a first conductivity type is provided. A plurality of first trenches arranged side by side in a first stripe layout extending along a first direction in a first preset area of the semiconductor substrate are formed. A plurality of second trenches arranged side by side in a second stripe layout extending along a second direction perpendicular to the first direction in a second preset area of the semiconductor substrate are formed. The plurality of first trenches and the plurality of second trenches are filled with a conductive material so as to form a plurality of control gates.

Claim (Index 4):
The method of  claim 3 , wherein the step of filling the plurality of first trenches and the plurality of second trenches with the conductive material so as to form the plurality of control gates comprises:\n depositing the conductive material on the semiconductor substrate so the plurality of first trenches and the plurality of second trenches are filled with the conductive material; and etching away an excessive portion of the conductive material so that the plurality of control gates are formed from a remaining portion of the conductive material in the plurality of first trenches and the plurality of second trenches.
