Sapphire Wafer (Tokyo) - Namiki Produce sapphire wafer 2, 3 and 4 for blue/white LED and LD. (c-plane & r-plane) We satisfy highly demanding requirements in the compound semiconductor industry for its surface bow, thickness variation, scratch and contamination with our precision processing technologies, featuring the most suitable crystal orientation (c-plane) off-angle for lll-Nitride EPITAXIAL Growth with form of concave surface. Our primarily established factory production lines only for sapphire wafer have ever processing from growing single crystal sapphire to scribing, grinding, high accurate polishing and quality inspection within the production lines that enable to mass-production. Namiki also offers any desired forms, any orientation and its accuracy to meet various needs in the blue/white LED industry. (sapphire, wafer, LED, LD, GaN, substrate, MOCVD, HVPE)
OKAMURA,Consultant (Kanagawa) -(2000) I am a consultant covering surface finishing such as electroless nickel plating, its recycling and application developing, and Mg, Al, Ti treating, and manufacturing process and quality certification of disk substrate. Moreover, I have much concern to reduce standby mode electricity in electrical appliances. (consultant, surface, finishinng, electroless, nickel, plating, recycle, disk, substrate, standby)
