A study of ohmic contacts on β-SiC

Abstract
A study on ohmic contacts on β-SiC is reported. The contacts were formed using titanium, tungsten, and their silicides. The tungsten and titanium contacts exhibited ohmic behaviour following annealing at a low-temperature (300°C) but deteriorated when annealed at 600°C. The minimum contact resistance for titanium and tungsten on SiC was 7.6 ×l0−3 and 6.1 × 10−3ohm-cm2, respectively. The silicides of titanium and tungsten yielded a lower contact resistance than the metallic Ti and W. The minimum contact resistance for TiSi2 and WSi2 is 1.1 × 10−4 and 3.0 × 10−4ohm-cm2, respectively.
