  • Patent number: 7112471
    Abstract: A leadless image sensor package and methods for its assembly. In a first embodiment, an image sensor chip is mounted within a bottom-side cavity of a package shell in a flip-chip manner such that sensing circuitry on the image sensor chip is exposed through an aperture in the top side of the package shell. A transparent encapsulant material is deposited within the aperture to encase interconnect bonds between the package shell and the image sensor chip. A transparent lid is held in place over the aperture by the encapsulant material. The back surface of the image sensor chip is left exposed. In a second embodiment particularly suitable for high-end image sensors, an encapsulant material is not required. Instead, a backing cap is hermetically sealed to a ledge surface in the package shell to cover the bottom-side cavity. A compression member formed on the backing cap contacts the image sensor chip and maintains interconnect bond integrity.

    Abstract: The present invention defines a packaging implementation providing a multichip multilayer system on a chip solution. Greater integration of a plurality and variety of known good die contained within cavities formed in a separate substrate is achieved. Additional redistribution and interconnect layers above the multichip configuration may be formed with the redistribution layers terminating in electrical connections such as conductive bumps or balls. In one embodiment, the substrate cavities receive signal device connections, such as conductive bumps, of a plurality of semiconductor dice in a flip-chip configuration. A portion of the substrate's back surface is then removed to a depth sufficient to expose the conductive bumps. In another embodiment, the cavities receive the semiconductor dice with their active surface facing up, wherein metal layer connections are formed and coupled to bond pads or other electrical connectors of the semiconductor dice.

The package, in one embodiment, includes an adhesive layer applied to an active side of the wafer. The adhesive layer has openings to permit access to the conductive pads on each die. A conductive material substantially fills the openings. A pre-packaged die diced from the semiconductor wafer is mounted to a support wherein the conductive material effects electrical interconnection between the conductive pads on the die and receiving conductors on the support. The pre-packaged die can be coupled to a processor for an electronic system. To provide greater mounting densities, two or more dice may be coupled with the adhesive layer providing a covering for the two or more dice.

The package, in one embodiment, includes an adhesive layer applied to an active side of the wafer. The adhesive layer has openings to permit access to the conductive pads on each die. A conductive material substantially fills the openings. Once diced from the wafer, the pre-packaged die is then surface mounted to a support wherein the conductive material effects electrical interconnection between the conductive pads on the die and receiving conductors on the support. In one embodiment, the package is heated to reflow the conductive material and bond the adhesive layer to the support. In another embodiment, the adhesive layer and conductive material are joined to the support by application of pressure. A protective layer is optionally formed on the back side of the wafer before dicing to complete the wafer package.
