Abstract

Time evolution of self-heating and current filamentation are discussed in this paper for shallow-trench-isolation (STI)-type drained-enhanced n-channel metal-oxide-semiconductor (DeNMOS) devices. A deeper insight toward regenerative n-p-n action and its impact over various phases of filamentation and the final thermal runaway is presented. A modified STI-type DeNMOS device is proposed in order to achieve an improvement (~2×) in the failure threshold (IT2) and electrostatic discharge (ESD) window (VT2). The performance and filament behavior of the standard device under charge-device-model-like ESD conditions is also presented, which is further compared with the proposed modified device.
