Abstract

It is demonstrated that buried layers of β SiC can be fabricated within single crystal silicon substrates by implanting high doses of energetic carbon ions. If the implantation temperature is sufficiently high >625°C then the β SiC grows epitaxially within the silicon, during implantation, using the substrate as a seed. During the subsequent high temperature anneal redistribution of the implanted species occurs to give a well defined buried layer of β SiC overlain by single crystal silicon.
