Experimental results show that SiC MOSFET exhibits shorter short circuit withstand time (SCWT) compared to Si IGBT. 1-D transient finite element thermal models of SiC MOSFETs and Si IGBTs have been implemented to simulate the dynamic temperature profiles in devices during short circuit tests. The junction temperature of SiC MOSFET rises much faster than that of Si IGBT and the heat spreading thickness of SiC MOSFET is much narrower, leading to shorter SCWT of the SiC MOSFET. Combining the experimental and thermal simulation results, the temperature-dependent saturation drain current in SiC MOSFETs is extracted. Based on this, the channel mobility over a wide temperature range is obtained.","PeriodicalId":202561,"journal":{"name":"2017 29th International Symposium on Power Semiconductor Devices and IC's (ISPSD)","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122110351","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}

The measured results of 1200 V diode show that the total loss and dynamic behavior such as the recovery softness and the dynamic ruggedness are greatly improved thanks to the proposed vertical concept. These improvements are the result of controlling the charge-carrier plasma layer and moderating the electric field gradient in CPL zone during the recovery operation.

In this work, we comprehensively studied the impact of a floating termination at the p-shield region on device performance. The SiC trench MOSFET's internal dynamics is revealed with numerical simulations. It is found that a lloating p-shield can effectively reduce the OFF-state electric-field in the bottom gate oxide of a SiC trench MOSFET without degrading its static performance. However, during switching operation, holes would be emitted out of the floating p-shield which then becomes a region that stores negative charges. The charge storage effect could then dramatically elevate the ON-state oxide field after the device is switched from the OFF-state, and also result in slower switching speed. The stored negative charges would also narrow the ON-state current path, and consequently, the dynamic äon would be degraded.","PeriodicalId":202561,"journal":{"name":"2017 29th International Symposium on Power Semiconductor Devices and IC's (ISPSD)","volume":"588 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115979036","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}

The AB RC-IGBT features a buffer layer with alternately doped N+ and P regions. The AB is separated from the collector by a part of N-drift region. The P buffer serves as the electron barrier during the unipolar mode and forces the electrons to flow through the high-resistance N-drift region between the buffer and the collector. Consequently, the snapback is suppressed with a fairly small cell pitch of 30μm. In the blocking state, the P buffer is fully depleted while the N+ buffer is not fully depleted yet. Therefore, the electric field terminates in the buffer layer and a high BV is ensured. The turn-off loss of the proposed AB RC-IGBT is reduced by 20% compared with that of the conventional RC-IGBT for the same forward on-state voltage drop.","PeriodicalId":202561,"journal":{"name":"2017 29th International Symposium on Power Semiconductor Devices and IC's (ISPSD)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116682082","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}
