GaN LEDs on Flexible Metal Foils
Technology Description:
iBeam Materials is developing a scalable manufacturing method to produce low-cost gallium nitride (GaN) LED devices for use in solid-state lighting. iBeam Materials uses an ion-beam crystal-aligning process to create single-crystal-like templates on arbitrary substrates thereby eliminating the need for small rigid single-crystal substrates. This process is inexpensive, high-output, and allows for large-area deposition in particular on flexible metal foils. In using flexible substrates, in contrast to rigid single-crystal wafers, the ion-aligning process also enables roll-to-roll (R2R) processing of crystalline films. R2R processing in turn simplifies manufacturing scale-up by reducing equipment footprint and associated labor costs By fabricating the LED directly on a metal substrate, one “pre-packages” the LED with the reflector and the heat sink built-in. This significantly reduces cost, simplifies packaging and allows a pick-and-place (P&P) technology to be replaced with printing of LEDs.
Potential Impact:
If successful, iBeam Material’s GaN coating on inexpensive large area substrates could significantly reduce the manufacturing cost of GaN based LEDs used in Solid State Lighting, accelerating their widespread use.
Security:
A large fraction of US electricity (18%) is used for lighting. The widespread deployment of LED-based solid state lighting (SSL) would reduce the demand for electricity which would in turn would help reduce U.S. oil imports.
Environment:
Widespread adoption of efficient solid state lighting promises to reduce electricity consumption, resulting in fewer harmful energy-related emissions.
Economy:
Widespread adoption of efficient solid state lighting would use less energy, saving American families and business owners’ money on their power bills.
