摘要

The Smart Cut~(TM) technology, now recognised as the technology of choice for the manufacturing of SOI substrates (Silicon On Insulator) [G. G. Shahidi, IBM J. Res. & Dev. 46, No. 2/3 (March and May 2002)], has got the unique potential to propose high quality Compound Semiconductors On Silicon (CSOS) substrates as a complementary technology to epitaxy. The use of this technology has led to the development of SiCOI (SiC On Insulator) structures where a thin film of single SiC crystal is bonded onto an oxidized substrate such as, for instance, a silicon substrate [L. Di Cioccio et al., Mater. Sci. Eng. B 46, 349 (1997)]. In this paper, we present the recent developments of SiCOI substrates developed using the Smart Cut~(TM) technology as well as the first results of GaN epitaxy performed onto these new structures. As a proof of concept and demonstration of feasibility, a Molecular Beam Epitaxy (MBE) GaN layer has been grown onto SiCOI substrate small samples and has been compared with similar growth on SiC bulk substrate.
