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 device can also include a first mesa defined by a first sidewall of the trench and in parallel with the trench and a second mesa defined by a second sidewall of the trench and in parallel with the trench. The first mesa can include at least one active segment of the IGBT device and the second mesa can include at least one inactive segment of the IGBT device.
