Abstract:
1. A process for fabricating a micro-display, comprising: providing a wafer, wherein the wafer has a driving circuit formed thereon; forming a metallic reflective layer on the wafer; forming an anti-reflection layer and a patterned photoresist layer in sequence over the metallic reflective layer; forming a trench pattern in the anti-reflection layer and the metallic reflective layer using the patterned photoresist layer as an etching mask to expose the surface of the wafer; removing the patterned photoresist layer; forming a dielectric layer to cover the anti-reflection layer and fill the trench pattern; and removing the dielectric layer and the anti-reflection layer above a top surface of the metallic reflective layer until the surface of the metallic reflective layer is exposed, so that a remained dielectric layer and the metallic reflective layer with the trench pattern are remained to form a part of the micro-display.
