Cree’s XThin LEDs are the next generation of solid-state LED emitters that combine highly efficient InGaN materials
with Cree’s proprietary GSiC substrate to deliver superior price/performance for high-intensity LEDs. These LED
chips have a geometrically enhanced Epi-down design to maximize light extraction efficiency and require only a
single wire bond connection. These vertically structured LED chips are approximately 115 microns in height and
require a low forward voltage. Cree’s XT chips are tested for conformity to optical and electrical specifications and
the ability to withstand 1000V ESD. Applications for XThin LEDs include next-generation mobile appliances for use
in their LCD backlights and digital camera flash where brightness, sub-miniaturization, and low power consumption
are required.
