ROHM utilizes original crystal technologies with metal organic chemical vapor deposition, or MOCVD. Proprietary techniques are employed for controlling the heteroepitaxial growth interface and developing high-efficiency quantum well active layers for all types of products. ROHM has also established a defect-free crystal compound semiconductor microfabrication technology that allows them to achieve high reliability devices. The assembly process lines ensure high quality. In-house production equipment, which has been continuously upgraded for over 30 years, results in optimal process lines.
