Making History

Founded in 1994, GTAT is at the forefront of technical innovation for advanced materials and crystal growth technologies. From the early 2000s, when we developed the first directional silicon solidification (DSS) furnace, to 2017 when we developed a breakthrough process for producing six-inch silicon carbide boules, we have consistently developed solutions that deliver sustainable value for customers in the Photovoltaic, Power Electronics and Laser and Optical markets.

Our latest innovations, Tube Filaments and the Continuous Cz Feeder, extend this long tradition of developing next generation technologies that support growth, lower production costs and enhance performance.
