For the first time, E2LIGBTs have exceeded the counterpart lateral DMOS both in switching speed and in on-resistance. The superior performance is achieved by the novel anode structure consisting of a narrow p+-injector and a wide Schottky contact on a lightly doped p-layer over an n-buffer. The on-state voltage can be further reduced to 3.0V at 84 A/cm2 by introducing Carrier Storage (CS) layer.

The sensefet matching properties to the main power mos represent the main quality factor of the device. Its current should be proportional to the main power one, maintaining the same coefficient over the entire temperature and biasing working range. In this work the effects of the edge cells layout and process are analyzed by the help of 3D device simulations. The causes for the real to theoretical ratio mismatch and the drift behavior versus the temperature are put into evidence. The corrective actions allow to reach 1÷2% of drift in the range -40°C to 150°C.

It is discovered for the first time that these two phenomena act as separated heat sources and induce one local hot spot which causes the thermal destruction in the edge termination during large current and high voltage turn-off switching. A novel edge termination design called “Partial P Collector” is proposed and evaluated. The novel design reduces current crowding and relaxes electric field in the edge termination. Simulated and measured results show that the failure mode of the novel design is determined by current filament phenomenon inside active cell region. It concludes that HV LPT(II)-CSTBT™(III) utilizing Partial P Collector edge termination design has ultra robust turn-off capability without deteriorating other electrical performances.","PeriodicalId":371298,"journal":{"name":"2012 24th International Symposium on Power Semiconductor Devices and ICs","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114966254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
