Aledia selects Veeco Propel GaN MOCVD platform for large wafer 3D LED production

Veeco Instruments Inc. today announced that Aledia, a developer and manufacturer of next-generation 3D LEDs for display applications based on its gallium-nitride-nanowires-on-silicon platform, has selected Veeco’s Propel® GaN MOCVD system to support advanced research and development. Aledia noted the tool’s large process window, single-wafer reactor technology and defect stability as key factors in its decision to adopt the Propel system.

“We believe that the opportunity for our breakthrough nanowire-LED display technology on large-area silicon is very large, and we need the best and most scalable technology available to support our continued R&D around 3D display applications—we believe Veeco is best positioned,” stated Giorgio Anania, CEO, chairman and co-founder of Aledia. “Veeco’s cutting-edge Propel system delivers unsurpassed results, and very good homogeneity throughout the entire wafer, making it the best choice and one we know will help us continue to push the limits of innovation.”

Aleida 3D Microwire LED Technology

Aledia is the first company to grow high-density, coaxial gallium nitride (GaN) microwires directly onto large-diameter 200mm silicon wafers (extendable to 300mm wafers) using low-cost processes that are fully compatible with the back end of line of today's semiconductor foundries. When processed these nanowires become LEDs.

 

Aledia's 3D nanowire-on-Silicon LED technology enables the next generation of displays, that can be brighter, can give longer battery life, can have more stable colors, and can be mass manufactured on existing foundries at very competitive cost points. (Aledia.com)

 

 

3D (Microwire) LEDs:

• Large, economical substrate
• Fast MOCVD growth process (low capital expenditure)
• Low materials consumption
• Existing high-volume silicon wafer fabs
• Light emission area = up to 3X the 2D area = more light/mm² or less current density, less efficiency droop
• Multiple colors on one wafer or even on one chip
