Initial results on thick 4H-SiC epitaxial layers grown using vapor phase epitaxy
Epitaxial layers of 4H-SiC of up to 120 micron thickness have been grown by vapor phase epitaxy using a tantalum carbide-coated susceptor surrounded by graphite foam. Background doping levels due to N and Al impurities were in the low 10(15) cm(-3) range. The electrical and optical properties of these layers are comparable to those grown using conventional vapor phase epitaxy.
