Abstract:
A semiconductor device and a method of forming the same are provided. A substrate is provided. A trench is formed in the substrate and a conductive material is formed filling the trench. A portion of the conductive material filling an upper portion of the trench is removed to expose an upper surface of the substrate and an upper corner and an upper sidewall of the trench. A doping process is performed to form a doped region in the substrate along the exposed upper surface of the substrate and the exposed upper corner and upper sidewall of the trench. The doped region has an upside-down L shape.

Claim (Index 4):
The method for forming a semiconductor device according to  claim 3 , wherein the step of removing a portion of the conductive material comprises:\n removing a portion of the barrier layer until a top surface of the barrier layer is flush with the top surface of the conductive material.
