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 9):
A semiconductor device, comprising:\n a substrate having an upper surface; a trench formed in the substrate; a conductive material formed in the trench and having a top surface lower than the upper surface of the substrate and exposing a top corner and an upper sidewall of the trench; and a doped region having an upside-down L shape formed at the top corner of the trench and having a horizontal portion extending along the upper surface of the substrate and a vertical portion extending along the upper sidewall of the trench.
