Abstract

See full text

A power transistor having a semiconductor barrier region is presented. A power unit cell of the power transistor has at least two trenches that may both extend into the semiconductor barrier region. The semiconductor barrier region may be p-doped and vertically confined, i.e., in and against the extension direction, by the drift region. The semiconductor barrier region can be electrically floating. Further, the at least two trenches may both increase in width along their respective extension into the semiconductor body.
