GTAT Introduces 150mm Bulk SiC


CrystX SiC crystal targets rapidly expanding electrical vehicle market

GTAT Corporation, an advanced materials company, is introducing its CrystX SiC material for use in power electronics applications such as electric vehicles.

With decades of experience in crystal growth, GT Advanced Technologies is producing CrystX SiC in increasing volume for growing markets that demand the technical advantages the material enables. “Our heritage in crystal growth gives us a tremendous platform from which to produce CrystX SiC with an aggressive cost-down focus going forward,” said Greg Knight, GTAT's president and CEO.

“We are at-scale now for volume production and can add capacity more rapidly than anyone in the industry.” SiC will allow electric vehicles to have markedly better range because the material enables much smaller and lighter modules and circuits. This holds true for other industrial applications where high-power and high-temperature demands preclude the use of more common silicon material.

CrystX SiC is available from GTAT in bulk-crystal form and ready for wafering. Presently, the available form factor for CrystX SiC is 150 mm diameter and with a target usable height of 25 mm or greater. “The rapidly-growing power-electronics and EV markets can now take advantage of our ability to produce exceptionally high-quality CrystX SiC at volumes and cost structures that global markets will demand,” concluded Knight.
