IGBT Having a Barrier Region

IGBT Having a Barrier Region

An IGBT having a barrier region is presented. A power unit cell of the IGBT has at least two trenches that may both extend into the barrier region. The barrier region may be p-doped and vertically confined, i.e., in and against the extension direction, by means of the drift region. The barrier regio...

Zusammenfassung:An IGBT having a barrier region is presented. A power unit cell of the IGBT has at least two trenches that may both extend into the barrier region. The barrier region may be p-doped and vertically confined, i.e., in and against the extension direction, by means of the drift region. The barrier region can be electrically floating.
