Abstract:
A semiconductor device includes a semiconductor substrate, a gate electrode, and a first contact plug. The semiconductor substrate includes a first surface and a second surface. Over the semiconductor substrate, a source region, a drain region, a drift region, and a body region are formed. A first trench in which the gate electrode is buried is formed in the first surface. The first surface includes an effective region and a peripheral region. The first trench extends from the peripheral region over the effective region along a first direction. The gate electrode includes a portion opposed to and insulated from the body region sandwiched between the source region and the drift region. In the peripheral region, the first contact plug is electrically coupled to the gate electrode buried in the first trench such that its longer side is along the first direction when seen in a plan view.

Claim (Index 9):
The semiconductor device according to  claim 8  further comprising a plurality of column regions of the second conductivity type extending from the body region toward the second surface,\n wherein the column regions are arranged in a staggered manner, being spaced from each other when seen in a plan view, and \n wherein the first trench, the second trench, the third trench and the fourth trench are so arranged as to pass through the column regions when seen in a plan view.
