iBeam Materials, a U.S.-based company focusing on technologies for crystal-aligned coatings utilizing ion-beam-assisted deposition (IBAD) texturing, announced that Samsung Venture has invested in the company as Samsung’s strategic investments in Micro LED.
iBeam pioneers in the development of ion-beam crystal alignment of thin layers deposited on a variety of substrates for optoelectronic devices. Its breakthrough in LED technology enables LEDs to be manufactured on large-area substrates as opposed to the much smaller single-crystal wafers currently used in the industry, according to Samsung Ventures.
The approach of iBeam is to use a metal foil substrate which provides strength and heat-sinking for large-area, bendable and rollable displays. The company is also working on integrating Micro LED monolithically with an active matrix circuit GaN FETs.

InGaN LEDs and GaN HEMT (High Electron Mobility Transistor) devices are currently manufactured on single-crystal wafers that limit the size and thermal management as well as cost reduction. iBeam Materials has demonstrated LEDs and HEMT devices using a patented alternative process that allows manufacturers to deposit epitaxial GaN devices directly on a variety of substrates including thin, flexible large-area metal foils. This process delivers much lower thermal resistance and enables roll-to-roll manufacturing capability.
