A semiconductor compound of gallium (Ga) and arsenic (As) is known as gallium arsenide. Gallium is a rare earth material and a bi-product manufactured during the smelting of aluminum and zinc, and arsenic is known to have poisonous properties. Gallium arsenide wafers can be manufactured using a number of manufacturing technologies, such as Liquid Encapsulated Czochralski (LEC) and Vertical Gradient Freeze (VGF).
