摘  要:SiC单晶片是第三代宽禁带半导体材料,其特有的晶体结构及高的材料硬度使其加工过程成为难点,突出表现为加工效率低、表面质量不稳定等问题,因此SiC单晶片的高效低损伤加工技术成为研究的焦点.介绍了SiC单晶材料去除机理,总结了高效精密加工SiC单晶的工艺现状及发展趋势,这对于提高SiC单晶片加工技术和应用水平有重要的理论意义和实用价值.
SiC single crystal is an important third generation of semiconductor materials.However,as a typical material difficult to machine,there is no mature machining technology for SiC single crystal.High efficient and low damage machining technology has become the main obstacle for its industrial application.The material remo-val mechanism of SiC single crystal is analyzed in detail and new machining processes are summarized.The problems that still exist by now are pointed out and the development tendency is discussed.They have great theoretical significance and applied value to promote the application of SiC single crystal in the semiconductor field.
