May 4, 2012 - BUSINESS WIRE -- Sapphire wafers grown using ARC Energy’s Controlled Heat Extraction System (CHES) furnaces for Trinity Material was certified for high-quality light-emitting diode (LED) chip production at two leading LED chip companies.
Trinity Material is ramping up for high-volume sapphire growth to produce large-diameter LED wafers, using ARC Energy furnaces. Trinity Material uses CHES furnaces to produce sapphire for 4” to 8” sapphire wafers.
ARC Energy’s CHES sapphire boule growth method uses the c-axis, instead of growing the boule on the a-axis and extracting wafers on the c-axis. CHES-produced sapphire wafers tested equal to or better than a-axis wafers in LED chip qualification. The company reports no color problems at the boule or wafer levels. CHES c-axis growth increases the light output of LED chips, said Champion Yi, chief operating officer for Trinity Material.
ARC Energy’s proprietary and fully automated CHES technology produces c-axis boules that are reportedly the optimum orientation for LED applications and enable higher materials utilization and lower costs compared with conventional a-axis technologies.
