Veeco Instruments Inc. reported that Swiss firm Exalos ordered a Propel® GaN Metal Organic Chemical Vapor Deposition (MOCVD) System. Exalos intends to utilize the Propel system for the research and development of high-performance broadband LEDs that the company calls superluminescent LEDs (SLEDs). This Swiss company is expected to receive the Propel system in the third quarter of 2018.
Christian Velez, CEO of Exalos commented, “The addition of this platform will enable us to achieve new levels of innovation and success.”
Veeco says it designed the Propel GaN MOCVD system to offer a wide process window and flexible configurations that can handle a broad range of GaN applications including advanced LEDs such as UVLEDs, SLEDs, laser diodes, as well as microLEDs and Power and RF components.
The system can process six and eight-inch wafers in single wafer mode, and in a mini-batch mode it can process two- to four-inch wafers. Veeco based the Propel reactor on the company’s TurboDisc® platform which utilizes the SymmHeat™ and the new IsoFlange™ technologies to provide uniform temperature profile across the entire wafer and deliver homogeneous laminar flow respectively.
Exalos SLEDs Produce Highly Directional Beam
Superluminescent LEDs employ electrical current injection to emit broadband light in a highly directional beam. According to Exalos, SLEDs are a hybrid between LEDs, which emit broadband light from a surface at wide angles and semiconductor laser diodes, which utilize a waveguide to emit narrowband light with a well-defined laser beam. The company also says that original equipment manufacturers use its SLEDs in optical sensing and metrology, motion control detectors, and navigation, as well as medical and industrial imaging.
“With over 400,000 SLED units shipped and strong technical expertise, Exalos is a proven leader in this space,” said Peo Hansson, Ph.D., senior vice president and general manager of Veeco MOCVD Operations.
