奈米碳管有著獨特的結構與優秀的電子特性，但是奈米碳管因其本身為奈米級的尺度，所以在製程上需要精確地被定位，無形中增加了奈米碳管電晶體元件製程的難易與時間，因此產生了將奈米碳管以隨機雜亂排列出來的奈米碳管網絡場效應電晶體。奈米碳管網絡可適用塗佈或轉印於任何的基板材料上，且奈米碳管不需精確地被組裝，只需要一般的黃光微影製程，減少元件的製程步驟並提高元件的生產效率，為奈米碳管網絡進入電子開關元件的一大重要利基。
本論文的第一章中，將從奈米碳管的發現介紹包括至奈米碳管的合成方式、晶格結構、電學特性與奈米碳管在電子元件上的應用。奈米碳管只要分佈的密度適當，彼此交錯的網絡結構就可形成連續的奈米碳管薄膜，所以在論文第二章將介紹常見的奈米碳管網絡製備方法。
論文第三章將介紹本實驗元件的結構與製程，以SiO2為閘極絕緣層的奈米碳管網絡電晶體製作程序容易且快速，但元件除了閘極施加效率不佳外，也因其背閘極結構無法同時對同一基板上其他的電晶體元件給予不同的閘極電壓，因此不適合用來製作邏輯電路。以Al2O3為閘極絕緣層的奈米碳管網絡電晶體採用局部背閘極結構製作，可在同一基板上各別定義不同元件的閘極，並且適用於邏輯電路，使用介電常數較高的Al2O3材料，可以有效增加閘極施加效率，大幅度降低元件的操作電壓。
第四章節將介紹奈米碳管網絡場效應電晶體的電性量測設備、量測軟體、 SWCNT/ SiO2元件與SWCNT/ Al2O3元件的電性量測結果，並將Al2O3奈米碳管網絡電晶體以鋁線焊線機作元件電極間的外部連接，進行反相器、反或閘和反及閘的邏輯電路操作。第五章將對本實驗元件的實驗結果作結論分析, 並對未來可能進行的研究工作進行探討。
