Results showed that three structural/chemical transformations took place upon annealing. The initial reaction (600–800 °C) involved the loss of hydrogen bonded to both silicon and carbon. At intermediate temperatures (900–1000 °C) a Si–O–C type bond was observed to form, and subsequently disappear after annealing to 1050 °C. The formation of ordered amorphous-SiC regions, nanocrystalline-Si regions, and stoichiometric, thermally relaxed SiO2 accompanied the disappearance of the Si–O–C bond at the 1050 °C annealing temperature. Using this alloy as a model system, important information is obtained for optimized processing of SiC–SiO2 interfaces for device applications.}, number={4}, journal={JOURNAL OF VACUUM SCIENCE & TECHNOLOGY A-VACUUM SURFACES AND FILMS}, author={Wolfe, DM and Hinds, BJ and Wang, F and Lucovsky, G and Ward, BL and Xu, M and Nemanich, RJ and Maher, DM}, year={1999}, pages={2170–2177} } @article{lucovsky_koh_chaflin_hinds_1998, title={Interfacial sub-oxide regions at Si-SiO2 interfaces: minimization by post-oxidation rapid thermal anneal}, volume={123}, ISSN={["1873-5584"]}, DOI={10.1016/S0169-4332(97)00528-X}, abstractNote={Transition regions at SiSiO2 interfaces contain su☐ide bonding arrangements which contribute to interface roughness and may give rise to electronically active defects. Interfacial transition regions with su☐ide bonding are a direct result of thermal and plasma-assisted oxidation at temperatures up to at least 800°C, but sub-oxide bonding is significantly reduced following a 30 s, 900°C RTA. The kinetics of annealing are essentially the same as those for separation of homogeneous sub-oxide thin films (SiOx, x < 2) into silicon nanocrystals and stoichiometric SiO2.}, journal={APPLIED SURFACE SCIENCE}, author={Lucovsky, G and Koh, K and Chaflin, B and Hinds, B}, year={1998}, month={Jan}, pages={490–495} } @article{hinds_wang_wolfe_hinkle_lucovsky_1998, title={Investigation of postoxidation thermal treatments of Si/SiO2 interface in relationship to the kinetics of amorphous Si suboxide decomposition}, volume={16}, number={4}, journal={Journal of Vacuum Science & Technology.

This paper presents experimental evidence for a kinetically-limited phase transition at SiSiO2 interfaces at approximately 900°C that can minimize and to a large degree eliminate significant interfacial sub-oxide transition regions. The paper emphasizes a connection between (i) differences in photoluminescence from SiOx bulk films before and after 900°C annealing and (ii) differences in electrical performance of SiSiO2 interfaces and optical second harmonic generation from SiSiO2 interfaces, also before and after 900°C annealing}, journal={APPLIED SURFACE SCIENCE}, author={Lucovsky, G and Banerjee, A and Niimi, H and Koh, K and Hinds, B and Meyer, C and Lupke, G and Kurz, H}, year={1997}, month={Jun}, pages={202–206} } @inproceedings{hinds_aspenes_lucovsky_1997, title={Low pH chemical etch route for smooth H-terminated Si(100) and study of subsequent chemical stability}, booktitle={Environmental, safety, and health issues in IC production: Symposium held December 4-5, 1996, Boston, Massachusetts, U.S.A.
