鰭式電晶體廣泛應用在許多3C產品中,例如:手機iPhoneA9處理器、電腦IC晶片……等,而在未來製程節點中,改善次臨界擺幅SS(Subthreshold Swing)降低元件之操作電壓與功率極為重要,本論文藉由導入HfZrO2鐵電材料當作電晶體的介電層,應用鐵電材料之負電容效應改善次臨界擺幅(SS)。 近期IBM團隊提出奈米片結構電晶體(Nanosheet FET),有別於鰭式電晶體,奈米片電晶體是參考Gate-All-Around(GAA)電晶體結構, Si通道設計成水平的結構,可有效解決鰭式電晶體鰭高的製程瓶頸,並廣泛應用在各大領域中,例如:人工智慧(AI)、虛擬實境(VR)……等,本論文是以鐵電材料HfZrO2作為介電層,應用於奈米片電晶體中,達到俱有鐵電負電容效應之奈米片電晶體,其中黃光製程部分皆使用I-line步進機,可以提高生產效率。
