Abstract

The silicon-adsorbed oxygen(Si-O) superlattice grown by ultra high vacuum-chemical vapor deposition(UHV-CVD) was introduced as an epitaxial barrier for silicon quantum electron devices. The current-voltage (I-V) measurement results show the stable and good insulating behavior with high breakdown voltage. It is apparent that the Si-O superlattice can serve as an epitaxially grown insulating layer as possible replacement of silicon-on-insulator(SOI). This thick barrier may be useful as an epitaxial insulating gate for field effect transistors(FETs). The rationale is that it should be possible to fabricate a FET on top of another FET, moving one step closer to the ultimate goal of future silicon-based three-dimensional integrated circuit(3DIC).

초고진공 화학기상증착장치(UHV-CVD)에 의해 성장된 실리콘-흡착된 산소(Si-O) 초격자가 실리콘 양자전자소자를 위한 에피택셜 장벽으로 소개되었다. 전류-전압 측정 결과 높은 브레이크다운 전압을 갖는 매우 안정하고 양호한 절연특성을 나타내었다. 에피택셜 성장된 Si-O 초격자는 SOI(silicon on insulator)를 대체할 수 있는 절연층으로도 사용될 수 있음을 보여준다. 이 두꺼운 장벽은 전계효과트랜지스터(FET)의 절연 게이트로 유용하게 사용될 수 있어 FET 위에 또 다른 FET를 제작할 수 있으므로 미래 실리콘계 3차원 집적회로의 궁극적인 목표에 한층 더 다가갈 수 있는 가능성을 보여주는 것이다.
