Abstract :
We study the side shape of an epitaxial growth layer on a monocrystalline shadow masked substrate (MSMG) and propose a method to control the side angle to obtain a truncated cone shaped total reflector with 45/spl deg/ side angle. We also propose a novel high radiance surface emitting LED (SE-LED) structure using the side angle controlled MSMG and predict several advantages of the proposed structure.
