METHOD OF FABRICATING A WAFER LEVEL OPTICAL LENS ASSEMBLY.

摘要

The present invention relates to method of fabricating a wafer level optical lens assembly, comprising: providing a wafer substrate having a plurality of lens shapes arranged side by side; providing a spacer substrate having a plurality of spacer posts; applying a first polymer liquid on a specific location chosen from the group of positions located on said wafer substrate between said plurality of lens shapes and positions located on the contact surface of said spacer posts, or a combination thereof; contacting said wafer substrate with said spacer substrate such that said spacer posts force said first polymer liquid to flow towards said plurality of lens shapes arranged side by side; curing said first polymer liquid; applying a second polymer liquid onto said plurality of lens shapes of said wafer substrate; curing said second polymer liquid to form a lens.
