Abstract:
1. A method of fabricating a wafer level optical lens assembly, comprising: providing a first wafer substrate having a plurality of bumps; applying a first polymer liquid on a first contact optical surface of said plurality of bumps; providing a second wafer substrate; contacting said first wafer substrate with said second substrate in such that said first polymer liquid is located in a slit created between said first contact optical surface of said plurality of bumps and said second wafer substrate under capillary forces; curing said polymer liquid(s) to form a lens; filling a third polymer between said first wafer substrate and said second wafer substrate utilizing a capillary phenomenon, and curing said third polymer to form an integral structure located between said first wafer substrate and said second wafer substrate, wherein said integral structure is separated by a plurality of lenses.
