Abstract
We have developed a chemi-mechanical surface preparation process for SiC which produces surface roughness values (Ra) below 5 angstroms and peak-to-valley variations (PV) below 55 angstroms. Non-contact surface profilometry, Atomic Force Microscopy, KOH etching, and Photon Back Scattering techniques have been compared for evaluation of surface finish quality. A short, low temperature KOH etch has been found to be a quick, effective method for revealing the degree of subsurface damage which does not directly correlate with surface roughness.
