ESI unveils LED wafer scribing system for high-volume HB-LED making

In booth 5871 at this week’s SEMICON West exhibition in San Francisco, ESI Inc of Portland, OR, USA, which provides laser-based manufacturing solutions for the microtechnology industry, is unveiling the AccuScribe 2600 LED wafer scribing system.

ESI says that it developed the AccuScribe 2600 on the basis of customer 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,” claims Jonathan Sabol, general manager of ESI’s LED uEngineering Division. “Industry-wide expansion of high-brightness LEDs is driving rapid changes in LED architecture and manufacturing processes to continuously increase lumens/watt,” he adds. “The AccuScribe 2600 is specifically designed to match our customers' most demanding technology roadmaps while achieving industry-best yield, performance and cost.”

ESI says that multiple customers have recently confirmed that the AccuScribe 2600 delivers the industry’s highest-brightness scribing for a wide range of HB-LED technologies, including PSS and DBR metal mirror. Increased light output results in increased revenue and profitability for LED makers, comments ESI. This, coupled with achieving the highest yield, lowest cost, least environmental impact, and complete elimination of employee work hazards related to chemical etching, will allow Accuscribe 2600 users to lead in the most profitable segment of the HB-LED market, the firm reckons.
