Abstract
The present invention provides method steps for manufacturing an assembly of adjustable lenses on a wafer. The method steps provide an easy manufacturing of such lenses, minimizing the cost of assembly, and at the same time provide a solution for mass production of compact adjustable lenses for use in mobile phones, etc.
Claims16
Method for manufacturing an adjustable lens assembly, wherein the method comprise the steps of:
- forming onto a transparent support a plurality of spacer members in a predefined grid pattern,
- applying by spin forming a pre-polymer on to the transparent support comprising the spacer members,
- attaching a continuous cover glass with pre-assembled actuators on top of the applied pre-polymer,
- masking a circular shaped part enclosing the actuators on top of the cover glass, and then etching providing a floating active disk on top of the pre-polymer comprising a circular shaped part of the cover glass with an actuator in the perimeter of the circular shaped cover glass part, and
- forming electrical contacts for the actuators.
