L-Monolithic RGB Epi

Multiple wavelengths are realized with one epitaxial growth.

Epi wafer with multiple wavelength
were grown in MOCVD.

Monolithic multicolor LED Epi wafer

Basically, this technique is applicable to all substrates(sapphire, Si, SiC and GaN).
Our epi technology can implement RGB pixel in a wafer at once.
