  • Patent number: 7534656
    Abstract: An image sensor device including a protective plate may be manufactured from an image sensor chip having an active surface and a back surface opposite to the active surface. The image sensor chip may include chip pads formed in a peripheral region of the active surface, a microlens formed in a central region of the active surface and an intermediate region between the peripheral and central regions. A protective plate may be attached to the intermediate region of the active surface of the image sensor chip using an adhesive pattern that is sized and configured to maintain a separation distance between the protective plate and the microlens formed on the image sensor chip. Conductive plugs, formed before, during or after the manufacture of the image sensor chip circuitry may provide electrical connection between the chip pads and external connectors.

  • Patent number: 7521657
    Abstract: An assembly may include a wafer and a plate may be mounted on the wafer. The wafer may have image sensor chips and scribe lines demarcating each image sensor chip. The image sensor chip may include an active surface. Chip pads and a micro-lens may be provided on the active surface. A photo-sensitive adhesive pattern may be provided between the plate and a region of the active surface between the chip pads and the micro-lens. An image sensor device implementing an image sensor chip having an individual plate may also be provided.

  • Patent number: 7371614
    Abstract: An image sensor device and methods thereof. In an example method, a protective layer may be formed over at least one microlens. An adhesive layer may be formed over the protective layer. The adhesive layer may be removed so as to expose the protective layer. The protective layer may be removed so as to expose the at least one microlens, the exposed at least one microlens not including residue from the adhesive layer. The at least one microlens may have an improved functionality due at least in part to the lack of residue from the adhesive layer. In an example, the at least one microlens may be included in an image sensor module.

  • Publication number: 20070264745
    Abstract: An image sensor device including a protective plate may be manufactured from an image sensor chip having an active surface and a back surface opposite to the active surface. The image sensor chip may include chip pads formed in a peripheral region of the active surface, a microlens formed in a central region of the active surface and an intermediate region between the peripheral and central regions. A protective plate may be attached to the intermediate region of the active surface of the image sensor chip using an adhesive pattern that is sized and configured to maintain a separation distance between the protective plate and the microlens formed on the image sensor chip. Conductive plugs, formed before, during or after the manufacture of the image sensor chip circuitry may provide electrical connection between the chip pads and external connectors.

  • Publication number: 20070045836
    Abstract: In a stacked chip configuration, and manufacturing methods thereof, the gap between a lower chip and an upper chip is filled completely using a relatively simple process that eliminates voids between the lower and upper chips and the cracking and delamination problems associated with voids. The present invention is applicable to both chip-level bonding and wafer-level bonding approaches. A photosensitive polymer layer is applied to a first chip, or wafer, prior to stacking the chips or stacking the wafers. The photosensitive polymer layer is partially cured, so that the photosensitive polymer layer is made to be structurally stable, while retaining its adhesive properties. The second chip, or wafer, is stacked, aligned, and bonded to the first chip, or wafer, and the photosensitive polymer layer is then cured to fully bond the first and second chips, or wafers. In this manner, adhesion between chips/wafers is greatly improved, while providing complete fill of the gap.
