  1. Sige simox : oxygen ions with high dose were implanted into sige grown directly on silicon substrate for the first time, and sige - oi novel structure was formed successfully with additional high temperature annealing ; it has been confirmed that oxygen implantation with 45kev, 3 1017cm - 2 and annealing at 12500c in ar + 5 % o2 for 5 hours, are fit for the formation of sige - oi structure ; ge loss during the high temperature annealing has been observed, which is originated from ge volatility and ge diffusion ; it has been proposed to use nanoporous layer induced by h + / he + implantation to surppress ge diffusion and to use surface oxidation to overcome the upper limit of sige simox. sige smart - cut : hydrogen ions were implanted into sige material and followed by high temperature process ( 4000c to 7000c ) ; blistering study was done and suggested the possibility of sige layer transfer by smart - cut technology ; it is concluded that the bubble formation is easier in sige than in si, and the strain in sige / si and the difference of binding energy in sige and in si could possibly contribute to this effect. behavior of sige / si implanted with hydrogen : gave a detailed study on sige implanted by beamline or phi hydrogen implantation ; it has been found that great strain is introduced into sige by hydrogen implantation and this strain could be alleviated by high temperature annealing ; both for conditional beamline implantation and piii hydrogen implantation, 600 is appropriate for the post - implantation treatment

    Sige - simox工藝方面：首次採用硅（ 100 ）襯底上直接外延的100nm厚sige的樣品中注入高劑量的o離子，通過退火處理成功制備了sige - oi新結構，即sige - simox工藝，證實了以45kev注入3 10 ~ （ 17 ） 7cm ~ （ - 2 ）劑量的氧離子，隨后在氧化層的保護下經1250 ， ar + 5 o _ 2氣氛的高溫退火（ 5小時）過程，可以制備出sige - oi新型材料；實驗中觀察到退火過程中的ge損失現象，分析了其原因是ge揮發（ ge通過表面氧化層以geo揮發性物質的形式進入退火氣氛）和ge擴散（ ge穿過離子注入形成的氧化埋層而進入si襯底中） ，其中ge擴散是主要原因；根據實驗結果及實驗中出現的問題，對下一步工作提出兩個改進的方案：一是通過在si襯底中注入適量h ~ + / he ~ +形成納米孔層來阻斷ge擴散通路，二是可以通過控製表面氧化來調節安止額士淤丈撈要表面sige層中的ge組分，從而部分解決sige
