SEMI's LED Standards Committee HB-LED Standard Published
After the formation of the high-brightness light-emitting diode (HB-LED) Standards Committee in November 2010 the committee was working hard on HB standards. The committee is happy to announce that it now has approved its first standard, SEMI HB1: Specifications for Sapphire Wafers Intended for Use for Manufacturing High Brightness-Light Emitting Diode Devices. Developed by the HB-LED Wafer Task Force, SEMI HB1 defines and specifies the physical geometry of 150 mm diameter sapphire wafers used in HB-LED manufacturing. HB1 covers dimensional, wafer preparation, and crystallographic orientation characteristics, as well as the appropriate measurement methods. The document was approved by the HB-LED Committee during the North America Fall 2012 meetings, recently completed procedural review and will be published soon. Read more »
