One direct approach to improve both these characteristics is to increase the proportion of the p+ region in the device. However, increasing the p+ area reduces the Schottky contact region, resulting in a higher forward voltage drop and worse dynamic behavior. In this work, we propose a series of tests and discussions from the layout perspective to a complete systematic realization of surge current endurance capability and avalanche ruggedness. The proposed SiC JBS cell design can simultaneously enhance both the surge current capability and avalanche ruggedness compared to conventional designs. The test results reveal that the proposed design can improve the $I_{FSM}$ by 115.7% and enhance the $E_{AS}$ by 374.3% compared to the conventional cell design.

Additionally, the impact of the minimum temperature on the power cycling performance was examined. For this purpose, power cycling tests with temperature swings between 40 K to 100 K and at minimum temperatures of 20°C and 40°C are performed. The results confirm, that the lifetime of SiC MOSFETs is significantly underestimated at low temperature swings by state-of-the-art lifetime models, when the model is fitted to power cycling test results at high temperature swings, which is in agreement with previous reports. Furthermore, the test results suggest that the discrepancy increases even further towards lower temperature swings, which can be modeled by a change of the Coffin-Manson exponent at a threshold temperature swing. This could be a possible indication of the transition from plastic to elastic deformation as the prevalent fatigue mechanism. Moreover, the tests at different minimum temperatures show a significantly higher impact of the baseline temperature on the lifetime at low temperature swings compared to high temperature swings. This may indicate that the threshold temperature swing for the transition from plastic to elastic deformation is impacted by the minimum temperature.","PeriodicalId":344266,"journal":{"name":"2023 35th International Symposium on Power Semiconductor Devices and ICs (ISPSD)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124685284","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}
