Abstract: A microlens has a surface with an effective index of refraction closer to the index of air than the body of the microlens to reduce reflection. Fibers protrude vertically from the surface of a microlens. For fabrication, the fibers are propelled at an adhesive layer provided over a microlens body and subjected to an electric field so that they stand vertically on the surface of the microlens. The adhesive layer is cured to hold the fibers in place.

Abstract: Ellipse-shaped microlenses focus light onto unbalanced photosensitive areas, increase area coverage for a gapless layout of microlenses, and allow pair-wise or other individual shifts of the microlenses to account for asymmetrical pixels and pixel layout architectures. The microlenses may be fabricated in sets, with one set oriented differently from another set, and may be arranged in various patterns, for example, in a checkerboard pattern or radial pattern. The microlenses of at least one set may be substantially elliptical in shape. To fabricate a first set of microlenses, a first set of microlens material is patterned onto a support, reflowed under first reflow conditions, and cured. To fabricate a second set of microlenses, a second set of microlens material is patterned onto the support, reflowed under second reflow conditions, which may be different from the first conditions, and cured.

Abstract: A microlens array with reduced or no empty space between individual microlenses and a method for forming the same. The microlens array is formed by patterning a first set of microlens precursors in a checkerboard pattern on a substrate. The first set of microlens precursors is reflowed and cured into first microlenses impervious to subsequent reflows. Then, a second set of microlens precursors is patterned in spaces among the first microlenses, reflowed and cured into second microlenses. The reflows and cures can be conducted under different conditions, and the microlenses may be differently sized. The conditions of the reflows can be chosen to ensure that the focal lengths of microlenses are optimized for maximum sensor signal.

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.

Abstract: A microlens structure includes lower lens layers on a substrate. A sputtered layer of glass, such as silicon oxide, is applied over the lower lens layers at an angle away from normal to form upper lens layers that increase the effective focal length of the microlens structure. The upper lens layers can be deposited in an aspherical shape with radii of curvature longer than the lower lens layers. As a result, small microlenses can be provided with longer focal lengths. The microlenses are arranged in arrays for use in imaging devices.
