Cree Inc of Durham, NC, USA, which makes LED chips, lamps and lighting fixtures plus gallium nitride and silicon carbide power-switching and RF/wireless devices as well as SiC substrates, says that it has achieved what it claims is a milestone in the development and commercialization of silicon carbide (SiC) technology with the demonstration of high-quality, 150mm-diameter SiC substrates with micropipe densities of less than 10/cm2.
Cree's current standard for SiC substrates is 100mm-diameter material.
