From the company’s web site:

“SemiLEDs is the only manufacturer of vertical LEDs on a metal alloy substrate; the MvPLEDTM. These devices are fabricated using SemiLEDs’ proprietary and patented technologies. MvPLEDTM is the next generation high power LEDs for solid state lighting applications.
SemiLEDs’ chip has been optimally designed, solving common problems of many conventional LEDs, such as thermal management and current spreading. With our breakthrough technology and innovation, our LED chips deliver better performance, capable of more than 100 lm/W at 350mA driving current. “

SemiLEDs’ vertical LEDs comprise a mirror directly deposited on metal alloy substrate, a 0.2 µm thick p-GaN/p-AlGaN layer, an InGaN/GaN multiple quantum well active region and a 4 µm thick n-GaN layer. Image and description source: compoundsemiconductor.net

“Utilizing Copper alloy substrate, SemiLEDs has successfully developed and commercialized  MvPLEDTM technology (Metal vertical Photon Light Emitting Diode). With metal substrate and unique device structure, SemiLEDs’ MvPLEDTM have better electrical and thermal conductivity; increasing brightness, efficiency, and better heat transfer. SemiLEDs’ MvPLEDTM  are suitable for lighting applications including display, signage, communication, automotive, and general lighting.”

“SemiLEDs is a U.S. corporation backed by multi-billion-dollar companies. The company is headquartered in Boise, Idaho with operations in Hsinchu, Taiwan.”
