本論文研究運用自主裝單分子層/二氧化矽堆疊感測薄膜來改善離子感應場效電晶體之效能。在量測實驗結果中,可以發現我們成功的利用單分子自主裝層-APTES改善了感測薄膜特性;在EIS的量測結果中,堆疊式感測薄膜的結構,不論是感測靈敏度、遲滯和時漂都有改善;除此之外,ISFETs的感測靈敏度,也有大幅度的提升。未來將可以單分子自主裝層/二氧化矽堆疊式感測薄膜搭配奈米線多通道離子感應場效電晶體,來製作高感測度的離子感應場效電晶體。
In this thesis, the SAM/SiO2 stacked sensing membrane was used to improve the sensing characteristic of ISFETs. In our results, the sensitivity, hysteresis and drift of EIS with the SAM/SiO2 stacked sensing membrane were all improved. Besides, the sensitivity of ISFETs was also improved. This technology will be suitable for the future high sensitivity ISFETs.
