Abstract: The present invention relates to method of fabricating a wafer level optical lens assembly. The method includes providing a wafer substrate having a plurality of lens shapes arranged side by side, and providing a spacer substrate having a plurality of spacer posts. The method further includes applying a first polymer liquid on a specific location chosen from the group of: (1) positions located on the wafer substrate between the plurality of lens shapes; (2) positions located on the contact surface of the spacer posts; and (3) a combination thereof. The method further includes contacting the wafer substrate with the spacer substrate such that the spacer posts force the first polymer liquid to flow towards the lens shapes, followed by curing the first polymer liquid, and applying a second polymer liquid onto the lens shapes.

Abstract: The present method relates to a method for printing a three-dimensional lens structure, comprising a step of depositing multiple fragments of printing material on a substrate and a step of curing the deposited fragments to build up said three-dimensional lens structure, wherein said substrate comprises a mould having a well defined surface area.
