ABSTRACT:
Asymmetrical structures and methods are used to adjust the orientation of a microlens for a pixel array. The asymmetrical structures affect volume and surface force parameters during microlens formation. Exemplary microlens structures include an asymmetrical microlens frame, base, material or a combination thereof to affect the focal characteristics of the microlens. The asymmetrical frame alters the microlens flow resulting from the heating of the microlens during fabrication such that orientation of the microlens relative to an axis of the imager can be controlled.
