Abstract:
This invention discloses a semiconductor power device disposed in a semiconductor substrate including an active cell areas and a termination area. The semiconductor power device further comprises a plurality of gate trenches formed at a top portion of the semiconductor substrate in the active cell area wherein each of the gate trenches is partially filled with a conductive gate material with a top portion of the trenches filled by a high density plasma (HDP) insulation layer. The semiconductor power device further comprises mesa areas of the semiconductor substrate disposed between the gate trenches wherein the mesa areas are recessed and having a top mesa surface disposed vertically below a top surface of the HDP insulation layer wherein the HDP insulation layer covering over the conductive gate material constituting a stick-out boundary-defining layer surrounding the recessed mesa areas in the active cell areas between the gate trenches.

Claim (Index 13):
The semiconductor power device of  claim 1  further comprising:\n a source metal layer covering over the active cell area and a gate metal layer covering over a termination area wherein the source metal and the gate metal are separated by a gap substantially aligned with one of the spacers adjacent one of the gate trenches functioning as a gate pickup trench disposed on an edge of the active cell area.
