(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)
- Based on its breakthrough technology in fabricating a less costly form of gallium nitride, Fuji Xerox has introduced UV caremate, a personal handy ultraviolet sensor in which users can check and monitor their personal UV exposure. UV caremate began sales in selected mass retail outlets on November 30. UV caremate measures the strength and amount of a user's UV exposure both indoors and outdoors and alerts the user of the safe exposure level with a built-in alarm. The unit uses rechargeable batteries with a life span of more than five days when fully recharged. (UV, ultraviolet sensor, gallium nitride, XP, SLE)
