Abstract:
1. A method for fabricating a flip-chip semiconductor optoelectronic device, comprising the steps of: providing an epitaxial substrate; forming a sacrificial layer on said epitaxial substrate, which comprises steps of: forming a semiconductor light-emitting structure on said sacrificial layer, said semiconductor light-emitting structure including a first surface and a second surface opposite to the first surface of said semiconductor light-emitting structure, wherein said sacrificial layer is on said second surface of said semiconductor light-emitting structure; forming an n-type electrode and a p-type electrode on said first surface of said semiconductor light-emitting structure; flip chip bonding said semiconductor light-emitting structure to a packaging substrate including a first surface, a second surface opposite to said first surface of said packaging substrate, a first bond pad formed on said first surface of said packaging substrate, a second bond pad formed on said first surface of said packaging substrate, a first bump formed on said first bond pad, and a second bump formed on said second bond pad, wherein said n-type electrode is electrically attached to said first bump, and said p-type electrode is electrically attached to said second bump; disposing a transparent adhesive material between said first surface of said packaging substrate and said first surface of said semiconductor light-emitting structure, enclosing said first bond pad, said second bond pad, said first bump, and said second bump; and separating said epitaxial substrate by etching said sacrificial layer.
