Abstract

Chemical and electrical studies were performed to determine the characteristics of contacts to 6H-SiC. Both elemental metals (Ni, Mo) and suicides (MoSi2, TaSi2, TiSi2) were studied. Chemical analysis by Auger Electron Spectroscopy (AES) was performed to examine interface reactions caused by heat treatment. Electrical measurements (current-voltage and capacitance-voltage) were made during annealing sequences to determine the rectifying or ohmic characteristics of the contacts. Where possible, barrier height and contact resistance values were calculated.
