    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: Formation of integrated color filters for gain-ratio balanced semiconductor array imagers using a spectrophotometric feedback control loop to adjust layer thickness during the deposition process is disclosed. The fabrication sequence of G/R/B conventionally used in Prior Art has been changed to B/R/G or B/G/R to enable the process to adapt to yielding specified color gain-ratio values without the need for integrated circuit redesign. A high efficiency color filter process is demonstrated wherein the additional neutral-density attenuator layers and/or spacer layers required in Prior Art fabrication methods are eliminated. The disclosed process is shown to enable high-precision thickness control of the color filter layers. Blue coating lift-off problems and the steric effect associated with successive depositions of color layers having step-height variations are eliminated. Statistical process control (SPC) is optimized by calibration of the color balance gain-ratio using the product photodiode arrays and amplifier integrated circuits with a real-time spectrophotometric feedback control-loop during the dye or pigment layer deposition process.

    摘要: The present invention features a method for forming micro lens arrays on light-sensitive or light-emitting semiconductor structures. A unique oxygen plasma etch “descum” step is performed prior to the lens reflow hardbake. In addition, a photo-sensitive planarization layer place immediately atop a color filter layer results in fewer process steps. The micro lens array thus formed has a minimal number of merged or collapsed lenses and residue on bond pad areas is significantly reduced.
