摘要

:碳化硅（SiC）具有高饱和漂移速度、高工作温度、更高的截止频率和最高频率（fT 和 fmax）、高热导率和高击穿电压（BV）等优异特性，因此是大功率电子器件的理想材料。随着半导体材料和加工技术的不断进步，各种大功率应用，如逆变器、电源、功率转换器和智能电动汽车，都采用了 SiC 功率器件。特别是 SiC MOSFET，由于其比 Si 基（绝缘栅双极晶体管）IGBT 具有更低的开关损耗、更高的开关速度和更低的导通电阻，因此在大功率应用中得到了广泛应用。本文对 SiC MOSFET 架构、新兴介电技术、迁移率增强方法和辐照效应进行了深入研究。此外，还简要概述了碳化硅功率器件的发展路线图。

Is SiC a Predominant Technology for Future High Power Electronics?: A Critical Review

: Due to the magnificent properties of Silicon Carbide (SiC), such as high saturation drift velocity, large operating temperature, higher cut-off and maximum frequency (fT and fmax), high thermal conductivity and large breakdown voltages (BV), it is desirable for high power electronics. With the latest advancements in semiconductor materials and processing technologies, diverse high-power applications such as inverters, power supplies, power converters and smart electric vehicles are implemented using SiC-based power devices. Especially, SiC MOSFETs are mostly used in high-power applications due totheir capability to achieve lower switching loss, higher switching speed and lower ON resistance than the Si-based (Insulated gate bipolar transistor) IGBTs. In this paper, a critical study of SiC MOSFET architectures, emerging dielectric techniques, mobility enhancement methods and irradiation effects are discussed. Moreover, the roadmap of Silicon Carbide power devices is also briefly summarized.
