    摘要: A new method of changing the surface property of a nitride film from hydrophobic to hydrophillic and thereby reducing nitride residue after photolithography is described. A pad oxide layer is provided on the surface of a semiconductor substrate. A nitride layer is deposited overlying the pad oxide layer. Thereafter, the surface of the nitride layer is cleaned wherein the surface is changed from hydrophobic to hydrophillic. The nitride layer is coated with a photoresist film which is developed to leave an opening where the field oxidation region is to be formed. The nitride layer and pad oxide layer are etched away where they are not covered by the photoresist film to expose a portion of the semiconductor substrate. The exposed portion of the semiconductor substrate is oxidized to form a field oxidation region in the fabrication of an integrated circuit.

    摘要: A new method is provided of treating the wafer prior to the process of singulating the wafer into individual die. A first surface of the wafer over which CMOS image sensor devices have been created is coated with a layer of material that is non-soluble in water. The wafer is attached to a tape by bringing a second surface of the wafer in contact with the tape. The wafer is singulated by approaching the first surface of the wafer and by sawing first through the layer of material that has been coated over the first surface of the wafer and by then sawing through the wafer, stopping at the surface of the tape. A thorough water rinse is applied to the surface of the singulated wafer, followed by a wafer clean applying specific chemicals for this purpose. The singulated die is now removed from the tape and further processed by applying steps of die mount, wire bonding, surrounding the die in a mold compound and marking the package.

    摘要: An image sensor device and method for forming said device are described. The image sensor structure comprises a substrate with photodiodes, an interconnect structure formed on the substrate, a color filter layer above the interconnect structure, a first microlens array, an overcoat layer, and a second microlens array. A key feature is that a second microlens has a larger radius of curvature than a first microlens. Additionally, each first microlens and second microlens is a flat convex lens. Thus, a thicker second microlens with a short focal length is aligned above a thinner first microlens having a long focal length. A light column that includes a first microlens, a second microlens and a color filter region is formed above each photodiode. A second embodiment involves replacing a second microlens in each light column with a plurality of smaller second microlenses that focus light onto a first microlens.
