VGF Grown Gallium Arsenide (GaAs)

We manufacture semi-insulating and Semiconducting Gallium Arsenide wafers and ingots by LEC (Liquid Encapsulated Czochralsky) or VGF (Vertical Gradient Freeze) growth method. Required electrical parameters are achieved through high purity 6N input material (Gallium and Arsenic). In order to attain the chosen level of concentration, the dopants like Zinc, Silicon and Tellurium are used. Get price
