ESI Inc., Portland, Ore., has unveiled its most advanced LED wafer scribing system, the AccuScribe 2600, which is based on user requirements for high brightness LED (HB-LED) manufacturing, including patterned sapphire substrate (PSS), distributed Bragg reflector (DBR), metal mirror (MM) and other advanced light extraction technologies.
"ESI pioneered the laser scribing of LED wafers with our patented technology for LED sapphire substrates," said Jonathan Sabol, GM of ESI's LED µEngineering Division. "Industry wide expansion of high brightness LEDs is driving rapid changes in LED architecture and manufacturing processes to continuously increase lumens/watt. The AccuScribe 2600 is specifically designed to match our customers' most demanding technology roadmaps while achieving industry best yield, performance and cost."
Increased light output results in increased revenue and profitability for LED manufacturers. This, coupled with achieving the highest yield, lowest cost, least environmental impact, and complete elimination of the employee work hazards related to chemical etching, will allow ESI Accuscribe 2600 users to lead in the most profitable segment of the high brightness LED market.
