项目摘要
Silicon carbide (SiC) is a promising semiconductor material for energy-saving power devices. However, because of its high hardness and brittleness, few conventional machining methods can handle this material efficiently. A plasma chemical vaporization machining (PCVM) technique, which is plasma etching using atmospheric-pressure plasma, has been considered for thinning and dicing process of SiC substrates by using the newly-developed PCVM apparatus. As a result of thinning experiments, a maximum removal rate of 500 nm/min was obtained over the entire 2-inch 4H-SiC (0001) wafer. And as a result of basic cutting experiments, a maximum removal rate of more than 0.01 mm/min with a groove width of less than 0.2 mm was successfully achieved.
碳化硅(SiC)是一种很有前景的节能功率器件半导体材料。然而,由于其高硬度和脆性,很少有传统的加工方法可以有效地处理这种材料。等离子化学汽化加工(PCVM)技术,即使用大气压等离子体的等离子蚀刻,已经考虑使用新开发的PCVM设备对SiC衬底进行减薄和切割加工。减薄实验的结果是,在整个 2 英寸 4H-SiC (0001) 晶圆上获得了 500 nm/min 的最大去除速率。基本切削实验的结果是,在槽宽小于0.2毫米的情况下,成功实现了大于0.01毫米/分钟的最大去除率。
