Silicon-on-Insulator Structure Fabricated by Electron Beam Evaporation of Si on Porous Si and Epitaxial Layer Transfer
-
Abstract
Epitaxial monocrystalline Si was grown on porous silicon by ultra-high vacuum electron beam evaporation. Results of reflection high energy electron diffraction, atomic force microscopy, cross-section transmission electron microscopy and Rutherford backscattering spectrometry and channeling (RBS/C) show a good quality of the epitaxial layer. Furthermore, silicon-on-insulator materials were successfully produced by bond and etch back of porous silicon. The quality of the silicon on insulator samples was investigated by RBS/C and spreading resistance profiling. Experimental results show that both the crystalline quality and electrical quality are good. In addition, the interface between the top Si layer and SiO2 buried layer is very sharp.
