Green Silicon Carbide (SiC) is an extremely hard (Mohs 9.4 / 2600 Knoop) man made mineral that possesses high thermal conductivity and high strength at elevated temperatures (at 1000°C, SiC is 7.5 times stronger than Al 2 O 3).SiC has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C, and it does not melt at normal pressures but instead dissociates at 2600°C.
Silicon carbide wafer lapping can minimize the burden on the final CMP step by creating a low Ra surface finish while maintaining superior flatness. This can be achieved in one or two steps, using successively softer lap plates and finer diamond slurry. The EJW-910 series is 6” SiC wafer compatible, with batch processing for efficiency.
Typically, Silicon Carbide is produced using the Acheson process which involves heating silica sand and carbon to high temperatures in an Acheson graphite resistance furnace. It can be formed as a fine powder or a bonded mass that must be crushed and milled before it can be used as a powder feedstock. Once the Silicon Carbide is in a powder form, the grains of the compound can be bonded
