Latest Patents

One of Sakuma's latest patents is a method for manufacturing a semiconductor device with increased breakdown voltage. This innovative method involves creating a first opening, ion-implanting an impurity of a second conductivity type, and forming a third semiconductor layer of the second conductivity type. The process begins with making the first opening in a second semiconductor layer, which is situated on a first semiconductor layer. The design of the first opening is such that its upper part has a longer dimension in a third direction than its lower part. This third direction is perpendicular to the first and second directions. The impurity is ion-implanted into the side surface of the lower part of the first opening, and the third semiconductor layer is formed within the first opening.

Another notable patent by Sakuma describes a semiconductor device that includes first semiconductor regions of a first conductivity type, spaced apart from each other, and second semiconductor regions of a second conductivity type positioned between adjacent first semiconductor regions. At least one of the second semiconductor regions features a void with a crystal plane orientation of (100). A third semiconductor region of the second conductivity type is placed on each second semiconductor region, while a fourth semiconductor region of the first conductivity type is positioned on the third semiconductor region. Each first semiconductor region is equipped with a gate electrode adjacent to a third semiconductor region via a gate insulation layer.
