Abstract: Stable, high temperature electrical contacts to silicon carbide formed using a unique silicide formation process that employs a sacial silicon layer between the silicon carbide and the contacting metal, which forms a metal silicide interlayer providing the resulting contact with low specific contact resistance and high electrical and structural stability.
Manufacturers of silicon carbide raw material and devices need to monitor and control these attributes to enhance yield. The first step in controlling these parameters is to measure them repeatably and quantifiably. Renishaw’s Raman systems are ideal for this.
Silicon carbide (SiC) is a wide band-gap semi-conductor material that is used increasingly for high voltage power devices, since it has a higher breakdown field strength and better thermal conductivity than silicon. However, in particular its hardness makes wafer processing difficult and many standard semi-conductor processes have to be specially adapted. We measure the effects of (i

1/4/2005· Two manufacturing protocols of silicon carbide (SiC) nanowires are discussed. The Raman spectra of produced SiC nanowires are compared with spectra of SiC powders of various grain sizes. The temperature and pressure dependence of the Raman spectra for powders is similar to that of bulk crystals, but is different for nanowires.
