Fabrication of Single-Crystalline SiC Layer on High-Temperature Glass
Single crystalline 6H-SiC layers have been transferred from SiC wafers implanted with H-2 at 160 keV with 5.0 x 10(16) ion cm(-2) onto a high temperature (800 degrees C) glass by anodic bonding and subsequent layer splitting at 725 degrees C. The relatively rough SiC surface (rms 20 Angstrom) prevents direct bonding but appears to be no obstacle for anodic bonding with glass. The activation energy of formation of optically detectable surface blisters caused by hydrogen filled microcracks in SiC samples served as a guideline to find a process window for the layer transfer approach.
