China’s HC SemiTek Corporation has purchased a Veeco TurboDisc MaxBright gallium nitride (GaN) metal-organic chemical vapour deposition (MOCVD) system for the high volume production of mainly GaN-based blue and green light emitting diode (LEDs) chips for display and general lighting applications. Placed in Q3/2012, the order was for Veeco’s new high performance (MHP) version of the system.

MaxBright MHP is designed to manufacture high quality, high brightness LEDs, by providing as much as 20% within-wafer wavelength uniformity improvement, enhanced serviceability and a 15% increase in footprint efficiency as compared to the MaxBright, says Veeco. Higher yields are achieved from improved thermal and flow capability. This system leverages Veeco’s production-proven Uniform FlowFlange technology and automation expertise by combining multiple high throughput MOCVD reactors in a modular 2- or 4-reactor cluster architecture.

Dr. Rong Liu, president of HC SemiTek, said, “Veeco’s MOCVD products offer stable process and have already helped us to successfully produce high quality, high brightness LEDs. The addition of MaxBright MHPs to our manufacturing line will allow us to ramp additional production quickly, due to the seamless process transfer from our existing Veeco toolset.”

Jeff Hawthorne, Veeco’s senior vice president, MOCVD, added, "We are pleased HC SemiTek has once again chosen Veeco’s MOCVD technology for their production requirements. The MaxBright MHP helps drive our customers’ productivity and yield, while reducing manufacturing costs.”
