論 文 摘 要
本研究目的為研究以晶圓接合技術應用於絕緣層上矽結構Silicon On Insulator(SOI)的各項性質,探討不同製程條件對接合界面之物理性質,包括鍵結強度、殘留應力、殘餘電荷等的影響。
本論文採用1000Å和3500Å兩種氧化層厚度,晶圓表面清洗方式則為親水性(SPM-M1)和斥水性(SPM-M2)兩種。經退火處理後之晶圓對,可發現其未鍵結區在退火後都可明顯縮小,且當氧化層愈厚時,其鍵結強度會隨之增加。同時,若經刀刃劈開之晶圓對,再次進行1000℃熱處理時,劈開之裂口將重新再癒合鍵結起來。另外,經歷過二次熱處理的SOI試片,其上層矽晶圓中,會殘留內壓應力,且當氧化層愈薄,殘留應力值會愈大。在SOI元件電性方面,可觀察到利用SOI製作MOSFET時,會比Bulk有較小的漏電流。由此實驗流程,可評估何種晶圓接合技術製作SOI時,可得到較佳之物裡性質,以利晶圓接合技術更廣泛地應用於微機電系統與積體電路系統中。
