Abstract

In a general aspect, an insulated gate bipolar transistor (IGBT) device can include an active region, an inactive region and a trench extending along a longitudinal axis in the active region. The IGBT can also include a first mesa defining a first sidewall of the trench and in parallel with the trench and a second mesa defining a second sidewall of the trench and in parallel with the trench. At least a portion of the first mesa can include an active segment of the IGBT device, and at least a portion of the second mesa can include an inactive segment of the IGBT device.
