High Brightness Light Emitting Diode (HBLED) is the new generation of lighting. HBLED is based on a more complex semiconductor P/N construction so it requires a higher level contamination controlling for its chemicals, gases, water and environment during each manufacturing step. Contaminants on the semiconductor can cause decreased yields, downtown and increase refection rates. Cobetter provides reliable filtration solutions for each manufacturing step including crystal ingot growth, wafer cleaning, MOCVD, CMP, Photolithography and etching.
