Description

When a dielectric isolated lateral insulated gate bipolar transistor (DI-LIGBT) on silicon-on-insulator (SOI) is turned on or off, a displacement current occurs in the surrounding area separated by dielectric isolation, referred to as a noise current in this note. We have determined this noise current during switching of the DI-LIGBT experimentally, and have investigated the dependence of its behavior on the cell pattern of the DI-LIGBT. The high noise current can be observed at the turn-on transient of the device, and its peak depends strongly on the cell pattern of the device structure.
