ABSTRACT:
A vertical structured Light Emitting Diode (LED) array using wafer level bonding. The process bonds two or more LED arrays vertically to produce light mixing in a small footprint. The vertically bonded LED array contains through substrate vias and a plurality of metal posts coated with solder to form an internal cavity between the LED layers. This LED array structure is intrinsically hermetically sealed.
