Semiconductors & Microelectronics
Compound semiconductors (GaN, GaAs, InP), fiber-optic waveguides, transparent conductive coatings (ITO), and high-reliability tantalum capacitors require trace byproduct metals recovered from aluminum, zinc, and tin smelting - including gallium, germanium, indium, arsenic, silicon, tantalum, and tin.
