Typical surface defects are small shallow depressions. 16% for epitaxial layers on the (0001)Si face with an off-angle of 8°. The epitaxial growth on the (11–20) face becomes very important, because the small channel mobility in the (0001)Si face of 4H-SiC can be dramatically improved by using the (11–20) face [85,86]. 8 SUMMARY This chapter has reviewed step-controlled epitaxial growth of SiC on off-axis SiC {0001} substrates. Step-flow growth is essential to realize polytype replication in epitaxial layers at rather low temperatures of around 1500°C without 3C-SiC inclusions.

Using an AFM (atomic force microscope) and a TEM for as-grown epitaxial layers on SiC {0001} substrates with off-angles of 3–10° along <11–20>. In AFM observations a distinctive difference in surface structures was observed on (0001)Si and (000–1)C faces. Epitaxial layers on a (0001)Si face with an off-angle of 5° of 6H-SiC yielded apparent macrosteps with a terrace width of 220–280 nm and a step height of 3–6 nm. 20 [52]. 20. Epitaxial layers on 4HSiC (0001)Si faces exhibited macrosteps with 110–160 nm width and 10–15 nm height in some regions.
