摘要: 碳化硅禁带宽、临界击穿场强大、热导率高,具有高压、高温、高频等优点。应用于硅基器件的传统封装方式寄生电感参数较大,难以匹配碳化硅器件的快速开关特性,同时在高温工况下封装可靠性大幅降低,为充分发挥碳化硅器件的优势需要改进现有的封装技术。针对上述挑战,对国内外现有的低寄生电感封装方式进行了总结。分析了现有的高温封装技术,结合新能源电力系统的发展趋势,对SiC器件封装技术进行归纳和展望。

Abstract: Silicon carbide (SiC) has the advantages of wide forbidden band, strong critical breakdown field, high thermal conductivity, high voltage, high temperature and high frequency. The traditional packaging method applied to silicon-based devices has large parasitic inductance parameters, which is difficult to match the fast switching characteristics of SiC devices. At the same time, the packaging reliability is greatly reduced under high temperature conditions. In order to give full play to the advantages of SiC devices, it is necessary to improve the existing packaging technology. In view of the above challenges, this paper classifies and compares the existing low parasitic inductance packaging methods at home and abroad. The existing high temperature packaging technology is analyzed. Finally, combined with the development trend of new energy power system, the SiC device packaging technology is summarized and prospected.

Key words: SiC, lowparasiticinductance, hybridpackaging, 3Dpackaging, planarinterconnection, double-sidedheatdissipation, hightemperaturepackaging
