A variety of structures and methods used to adjust the shape, radius and/or height of a microlens for a pixel array. The structures affect volume and surface force parameters during microlens formation. Exemplary microlens structures include a microlens frame, base, material, protrusions or a combination thereof to affect the shape, height and/or radius of the microlens. The frame, base and/or protrusions alter the microlens flow resulting from the heating of the microlens during fabrication such that a height or radius of the microlens can be controlled. The radius can be adjusted by the height differences between the microlens and frame. The bigger the difference, the smaller the radius will be.
