    摘要: A patterned mask can be formed as follows. A first patterned photoresist is formed over a masking layer and utilized during a first etch into the masking layer. The first etch extends to a depth in the masking layer that is less than entirely through the masking layer. A second patterned photoresist is subsequently formed over the masking layer and utilized during a second etch into the masking layer. The combined first and second etches form openings extending entirely through the masking layer and thus form the masking layer into the patterned mask. The patterned mask can be utilized to form a pattern in a substrate underlying the mask. The pattern formed in the substrate can correspond to an array of capacitor container openings. Capacitor structure can be formed within the openings. The capacitor structures can be incorporated within a DRAM array.

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

    摘要: 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.

    摘要: A micro-lens and a method for forming the micro-lens is provided. A micro-lens includes a substrate an lens material located within the substrate, the substrate having a recessed area serving as a mold for the lens material. The recessed can be shaped such that the lens material corrects for optical aberrations. The micro-lens can be part of a micro-lens array. The recessed area can serve as a mold for lens material for the micro-lens array and can be shaped such that the micro-lens array includes arcuate, non-spherical, or non-symmetrical micro-lenses.

    摘要: 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.

    摘要: A semi-conductor based imager includes a microlens array having microlenses with modified focal characteristics. The microlenses are made of a microlens material, the melting properties of which are selectively modified to obtain different shapes after a reflow process. Selected microlenses, or portions of each microlens, are modified, by exposure to ultraviolet light, for example, to control the microlens shape produced by reflow melting. Controlling the microlens shape allows for modification of the focal characteristics of selected microlenses in the microlens array.
