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.


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.


Widespread adoption of efficient solid state lighting promises to reduce electricity consumption, resulting in fewer harmful energy-related emissions.


Widespread adoption of efficient solid state lighting would use less energy, saving American families and business owners’ money on their power bills.
