簡介 Introductions

碳化矽可應用在次世代功率元件中，為下世代功率半導體元件的關鍵材料。因高硬度及高耐化性等難加工特性，導致使生產率低，阻礙功率元件發展潮流。本技術建立複合式研拋製程平台，透過導入超音波輔助加工技術及大氣電漿輔助改質技術，可大幅提升碳化矽晶圓產能效率及有效降低製造成本。

Silicon carbide can be used in next-generation power components and is a key material for next-generation power semiconductor parts. Due to difficult processing characteristics such as high hardness and high chemical resistance, the productivity is low and the development trend of power components is hindered. This technology establishes a hybrid-processing platform which includes ultrasonic assisted processing technology and atmospheric plasma assisted modification technology. It can greatly improve the production efficiency of silicon carbide wafers and effectively reduces manufacturing costs.
