Patent ID: 7335523

Claim:
A process of forming a light-emitting device, comprising: forming a light-emitting unit provided with a plurality of first connecting pads, wherein the light-emitting unit is configured to emit a first light radiation; forming a base substrate provided with a plurality of second connecting pads, wherein the base substrate is configured to emit a second light radiation when stimulated with the first light radiation; forming a plurality of conductive bumps on either the first or second connecting pads; placing the light-emitting unit and the base substrate so that the first light radiation and the second light radiation when being produced mix each other to create a visible color light different from the first and second light radiations, wherein forming the base substrate comprises: forming a luminescent layer; forming a passivation layer covering the luminescent layer; forming the second conductive pads over the passivation layer; and connecting the first and second connecting pads via the conductive bumps.
