    摘要: A method of forming a planarized photoresist coating on a substrate having holes with different duty ratios is described. A first photoresist preferably comprised of a Novolac resin and a diazonaphthoquinone photoactive compound is coated on a substrate and baked at or slightly above its Tg so that it reflows and fills the holes. The photoresist is exposed without a mask at a dose that allows the developer to thin the photoresist to a recessed depth within the holes. After the photoresist is hardened with a 250° C. bake, a second photoresist is coated on the substrate to form a planarized film with a thickness variation of less than 50 Angstroms between low and high duty ratio hole regions. One application is where the second photoresist is used to form a trench pattern in a via first dual damascene method. Secondly, the method is useful in fabricating MIM capacitors.

    摘要: An image sensor includes a double-microlens structure with an outer microlens aligned over an inner microlens, both microlenses aligned over a corresponding photosensor. The inner or outer microlens may be formed by a silylation process in which a reactive portion of a photoresist material reacts with a silicon-containing agent. The inner or outer microlens may be formed by step etching of a dielectric material, the step etching process including a series of alternating etch steps including an anisotropic etching step and an etching step that causes patterned photoresist to laterally recede. Subsequent isotropic etching processes may be used to smooth the etched step structure and form a smooth lens. A thermally stable and photosensitive polymeric/organic material may also be used to form permanent inner or outer lenses. The photosensitive material is coated then patterned using photolithography, reflowed, then cured to form a permanent lens structure.
