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 1):
A semiconductor device comprising:\n a cell region on a substrate and including a vertical transistor having a first trench; a cell outer peripheral region having a second trench connected to the first trench; a gate insulating film on a bottom surface and a side surface of the first trench and on a bottom surface and a side surface of the second trench up to a first height; and a gate electrode embedded up to the first height inside each of the first and second trenches along the gate insulating film, the cell outer peripheral region being configured to pull out a potential of the gate electrode, and having:\n a sidewall insulation region provided along the side surface of the second trench from the first height lower than a surface of the substrate and higher than the bottom surface of the second trench to a second height of the surface of the substrate; and \n a gate metal wiring having a lower portion contacting the gate electrode and being present in a region above from the first height inside the second trench, surrounded by the sidewall insulation region.
