It features the double hole-conductive paths formed by a top and a buried p-layer in the drift region using OPTVLD technique, which significantly contribute to reducing device specific on-resistance. The design principle and electrical characteristics of the proposed structure are investigated theoretically and experimentally. Simulation results show that the specific on-resistances are 155/689 mΩ·cm2 with breakdown voltages of 300/800 V for the proposed structure, respectively, which are less than 60% of that with corresponding breakdown voltages for the conventional structure. This structure used as high-side can apply to SPIC with a low integration difficulty and a low fabrication cost.","PeriodicalId":371298,"journal":{"name":"2012 24th International Symposium on Power Semiconductor Devices and ICs","volume":"18 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":"115936398","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}

In this work the prerequisites for valid field extraction and the (voltage) range of validity are established for linearly graded drain extension based RESURF devices through a combination of analytical calculations and TCAD device modeling. It is shown that the most important condition for field extraction is that an increment dVDS should not affect the lateral field at the already depleted zone. This unique condition is found to be met in the drain extension at distances larger than a specific length (5.3λ) governed by the drain extension silicon and oxide thicknesses. For realistic device parameters the method is shown to hold for devices with a BVDS of ~ 150V and higher.","PeriodicalId":371298,"journal":{"name":"2012 24th International Symposium on Power Semiconductor Devices and ICs","volume":"29 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":"131464971","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 leakage current of the proposed device was decreased by four orders of magnitude. The leakage current of the conventional device at room temperature was 80 μA/mm while that of the proposed device was 16.6 nA/mm. In the high temperature reverse bias (HTRB) test, the ratio of the gate leakage current to the total leakage was decreased with operational temperature. From experimental results of the HTRB test, it was demonstrated that NiOX-based double gate contact was thermally and electrically robust and made a significant contribution to stable blocking operation. In terms of the breakdown behavior, the device with a double metal structure successfully suppressed the premature breakdown while conventional one showed a soft breakdown behavior. The measured breakdown voltage (VBR) of the conventional device was 1310 V while VBR of the proposed device was 1480 V with almost no walkout. The stable reverse blocking characteristics of the proposed device was attributed to the resistance switching property of the nickel oxide film and the high barrier height established between thermally oxidized nickel film and surface of the device.","PeriodicalId":371298,"journal":{"name":"2012 24th International Symposium on Power Semiconductor Devices and ICs","volume":"58 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132708499","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}

With this technique, we have investigated dynamic RON transients over a time span of 11 decades. In OFF to ON time transients, we observe a fast release of trapped electrons through a temperature-independent tunneling process. We attribute this to border traps at the AlGaN barrier/AlN spacer interface. Over a longer time scale, we observe conventional thermally activated electron detrapping from traps at the surface of the device or inside the AlGaN barrier. These findings provide a path for power switching device engineering with minimum dynamic RON.","PeriodicalId":371298,"journal":{"name":"2012 24th International Symposium on Power Semiconductor Devices and ICs","volume":"103 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":"116410082","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}
