Design of edge termination on non-uniform 100-V super-junction trench power MOSFET

A design methodology for the edge termination is proposed to achieve the same breakdown voltage of the non-uniform super-junction (SJ) trench metal-oxide semiconductor field-effect transistor (TMOSFET) cell structure. A simple analytical solution for the effect of charge imbalance on the termination region is suggested, and it is satisfied with the simulation of potential distribution. The dopi...

Design of 100-V Super-Junction Trench Power MOSFET with Low On-Resistance

© 2012 ETRI Journal, Volume 34, Number 1, February 2012 Power metal-oxide semiconductor field-effect transistor (MOSFET) devices are widely used in power electronics applications, such as brushless direct current motors and power modules. For a conventional power MOSFET device such as trench double-diffused MOSFET (TDMOS), there is a tradeoff relationship between specific on-state resistance an...

A new junction termination technique: The Deep Trench Termination (DT2)

Numerous techniques have been used to improve the voltage handling capability of high voltage power devices with the aim to obtain the breakdown of a plane junction. In this work, a new concept of low cost, low surface and high efficiency junction termination for power devices is presented and experimentally validated. This termination is based on a large and deep trench filled by BCB (BenzoCyc...
