摘要: A semiconductor device includes first semiconductor regions of a first conductivity type spaced apart from each other and second semiconductor regions of a second conductivity type between adjacent first semiconductor regions. At least one second semiconductor region includes a void having at least one outer surface with a crystal plane orientation of (100). A third semiconductor region of the second conductivity type is on each second semiconductor region and a fourth semiconductor region of the first conductivity type is on the third semiconductor region. A gate electrode on is disposed on each first semiconductor region to be adjacent to a third semiconductor region via a gate insulation layer.

摘要: According to one embodiment, a method for manufacturing a semiconductor device comprises making a first opening, ion-implanting an impurity of a second conductivity type, and forming a third semiconductor layer of the second conductivity type. The first opening is made in a second semiconductor layer. The second semiconductor layer is provided on a first semiconductor layer. The first opening extends in a second direction. A dimension in a third direction of an upper part of the first opening is longer than a dimension in the third direction of a lower part of the first opening. The third direction is perpendicular to the first direction and the second direction. The impurity of the second conductivity type is ion-implanted into a side surface of the lower part of the first opening. The third semiconductor layer of the second conductivity type is formed in an interior of the first opening.

摘要: A semiconductor manufacturing apparatus includes a chamber, a reaction-gas inlet, a gas exhaust port, a rotation unit, a semiconductor wafer holder, a heater, and a purge-gas inlet. The wafer holder includes a first hold region to hold the semiconductor wafer and a second hold region held by the rotation unit. The second hold region surrounds the first hold region. The level of the first hold region and the level of the second hold region differ. A plurality of ventholes is provided to the first hold region so that the ventholes are just below a sidewall of the semiconductor wafer held by the first hold region.
