Abstract:
A semiconductor device in which a trench in a cell outer peripheral region configured to pull out a gate electrode and a trench in a cell region having a vertical transistor are formed with the same width to enable a reduction in chip area, and a manufacturing method thereof in which a gate contact hole is formed directly on a trench in a cell outer peripheral region on a self-alignment basis, and a gate wiring electrode is connected thereto are provided.

Claim (Index 9):
A semiconductor device comprising:\n a substrate; a cell region on the substrate and arranged with a vertical transistor having a first trench; and a cell outer peripheral region having a second trench connected to the first trench, each of the first trench and the second trench having: a gate insulating film on a bottom surface and a side surface thereof, and a gate electrode embedded into the first trench and the second trench respectively along the gate insulating film, the cell outer peripheral region having: a sidewall insulation region provided along either an inside surface or an outside surface of the second trench at least from an upper end of the gate electrode to an uppermost surface of the substrate, and a gate metal wiring provided in a region surrounded by the upper end of the gate electrode in the second trench and the sidewall insulation region.
