Metal organic (MO) compounds

High Purity Chemicals

Outline

Full-fledged application of compound semiconductors to optoelectronics, HEMT, and GaAs ICs is underway, and metal organic chemical vapor deposition (MOCVD) is being used as an epitaxial crystal growth method. UBE's MO compounds are highly rated for their extremely high purity made possible by our refining, analysis, and handling technology accumulated as a chemical manufacturer. Our company is now achieving one success after another in the III-V and III-VI family of metal organic chemical vapor deposition (MOCVD) materials.
