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： A new method to form passivation openings in the manufacture of an integrated circuit device is achieved. The passivation openings have gradually sloping sidewalls that allow a protective tape to be completely removed without leaving adhesive residue. A semiconductor substrate is provided. A passivation layer is deposited. An organic photoresist layer is deposited overlying the passivation layer. The organic photoresist layer is patterned to expose the passivation layer in areas where passivation openings are planned. The organic photoresist layer is reflowed to create gradually sloping sidewalls on the organic photoresist layer. The passivation layer is etched through to from the passivation openings. The passivation openings are thereby formed with gradually sloping sidewalls. The organic photoresist layer is stripped away. A protective tape is applied overlying the passivation layer and the passivation openings. The protective tape is removed. The gradually sloping sidewalls on the passivation openings allow the protective tape to be completely removed without leaving adhesive residue in the manufacture of the integrated circuit device.

摘要： A method for fabricating a microelectronic product provides for forming a planarizing layer upon a bond pad and a topographic feature, both formed laterally separated over a substrate. The planarizing layer is formed with a diminished thickness upon the bond pad such that it may be readily etched to expose the bond pad while employing as a mask an additional layer formed over the topographic feature but not over the bond pad. The method is particularly useful for forming color filter sensor image array optoelectronic products with attenuated bond pad corrosion.

摘要： A process for reworking a non-reflowed, defective microlens element shape, of an image sensor device, without damage to an underlying spacer layer, or to underlying color filter elements, has been developed. The non-reflowed, microlens element shape, if defective and needing rework, is first subjected to a high energy exposure, converting the non-reflowed, microlens element shape to a acid type, microlens shape, then removed using a base type developer solution. Prior to formation of a reworked microlens element shape a baking cycle is employed to freeze, or render inactive, any organic residue still remaining on the surface of the spacer layer, after the base type developer removal procedure. Formation of the reworked, microlens element shape, followed by an anneal cycle, results in the desired rounded, microlens element, on the underlying spacer layer.

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.
