摘要: 碳化硅(SiC)作为第三代宽禁带半导体材料,因优异的电学、热学与力学性能,在高温、高压、高频功率电子器件中具有广泛的应用前景。作为SiC的重要多型之一,立方相碳化硅(3C-SiC)具有更高的电子迁移率、更低的界面陷阱密度及更优的沟道性能,在中等电压范围内展现出较强的器件竞争力。本文综述了3C-SiC外延生长的研究进展,重点比较了化学气相沉积与升华外延法在生长工艺、缺陷演化及衬底选择方面的技术特点,分析了点缺陷、堆垛层错、反相畴界、表面凸起和应力等关键结构缺陷的形成机制及其对材料与器件性能的影响。此外,本文还总结了基于3C-SiC的功率二极管、MOSFET及异质结构器件的最新研究成果,展望了通过衬底工程、缺陷调控及工艺优化等手段提升3C-SiC外延质量与器件性能的未来发展方向。

Abstract: Silicon carbide (SiC), as a representative third-generation wide-bandgap semiconductor material, has demonstrated great potential for applications in high-temperature, high-voltage, and high-frequency power electronic devices due to its excellent electrical, thermal, and mechanical properties. Among the various SiC polytypes, cubic silicon carbide (3C-SiC) exhibits higher electron mobility, lower interface trap density, and superior channel characteristics, making it highly competitive for devices operating in the medium voltage range. This review summarizes the recent progress in the epitaxial growth of 3C-SiC, with a particular focus on comparing the characteristics of chemical vapor deposition (CVD) and sublimation epitaxy (SE) in terms of growth processes, defect evolution, and substrate selection. The formation mechanisms and impacts of key structural defects including point defects, stacking faults, anti-phase boundaries, surface protrusions, and residual stress are systematically analyzed. Furthermore, the latest advances in 3C-SiC-based power diodes, MOSFETs, and heterostructure devices are reviewed. Finally, future development directions for improving the epitaxial quality and device performance of 3C-SiC through substrate engineering, defect control, and process optimization are discussed.

Key words: cubic silicon carbide; chemical vapor deposition method; sublimation epitaxy method; epitaxial growth; defect; power device
