Electro-chemical mechanical polishing of silicon …

In an effort to improve the silicon carbide (SiC) substrate surface, a new electro-chemical mechanical polishing (ECMP) technique was developed. This work focused on the Si-terminated 4H-SiC (0001) substrates cut 8 off-axis toward 〈1120〉. Hydrogen peroxide (H 2 O 2) and potassium nitrate (KNO 3) were used as the electrolytes while using colloidal silica slurry as the polishing medium for
