Trinity Material,a company specializing in research, production and distribution of LED grade sapphire substrate materials, has qualified controlled heat extraction system (CHES) furnacesof ARC Energy, headquartered in Nashua, New Hampshire, to manufacture high quality LED chips at two major companies.
Both the companies have signed an agreement, under which Trinity Material will use ARC Energy’s CHES technology for sapphire wafer production.
Sapphire boules are produced on c-axis with the use of ARC Energy’s CHES furnace,whereas, in conventional processes boules are grown on a-axis and wafers on c-axis are extracted. Champion Yi, Trinity Material’s Chief Operating Officer, stated that LED chip qualification proves that wafers produced from the CHES technology perform better than sapphire materials grown by the conventional processes. In addition, LED chips produced on CHES wafers reveal a considerable boost in light output than the devices manufactured using wafers resulting from a-axis boules, added Yi. Additionally, the CHES technology increases material utilization and decreases total costs for production of large diameter sapphire substrates.
Trinity Material is now accelerating the production of large volumes of sapphire wafers to address the increasing demand in the LED market. The CEO of Trinity Material, Jamin Sheng, remarked that the partnership with ARC Energy will enable them to use innovativeCHES furnaces and will also allow them to increase their production capabilities, so that the company can attain a leadership position in large diameter sapphire.
