  • Patent number: 8067267
    Abstract: A method of making a stacked microelectronic assembly includes providing a first microelectronic package that includes a first substrate having a first dielectric layer, conductive posts, and conductive traces extending along the surface of the first dielectric layer; providing a second microelectronic package including a second substrate that includes a second dielectric layer; securing a microelectronic element to one of the surfaces of at least one of the first or second substrates; and joining the conductive posts of the first substrate with the fusible masses of the second substrate. The posts may include a plurality of aligned posts which are aligned in a first row extending in a single orthogonal direction along a surface of the first substrate away from a portion of the first substrate that faces a face of the microelectronic element. The aligned posts are disposed beyond one of the edges of the microelectronic element.

  • Patent number: 7534652
    Abstract: A dielectric structure is formed by a molding process, so that a first surface of a dielectric structure is shaped by contact with the mold. The opposite second surface of the dielectric structure is applied onto the front surface of a wafer element. The dielectric layer may include protruding bumps and terminals may be formed on the bumps. The bumps may be of a precise height. The terminals lie at a precisely controlled height above the front surface of the wafer element. The terminals may include projecting posts which extend above a surrounding solder mask layer to facilitate engagement with a test fixture. The posts are immersed within solder joints when the structure is bonded to a circuit panel.

  • Publication number: 20090071707
    Abstract: A method is provided for manufacturing a multilayer substrate. An insulating layer can have a hole overlying a patterned second metal layer. In turn, the second metal layer can overlie a first metal layer. A third metal layer can be electroplated onto the patterned second metal layer within the hole, the third metal layer extending from the second metal layer onto a wall of the hole. When plating the third metal layer, the first and second metal layers can function as a conductive commoning element.

  • Patent number: 7368695
    Abstract: An image sensor package is disclosed that reduces the overall size of known image sensor packages. The image sensor package includes an image sensor and image sensor controller that are arranged on a substrate so that the surfaces of the image sensor and image sensor controller are directly adjacent one another. A package in accordance with the present invention reduces the amount of space in the package by allowing at least one surface of the image sensor controller and at least one surface of the image sensor to be directly attached or connected to one another. Electrical conductive material in the nature of anisotropic conductive materials is also preferably applied to the substrate in the form of an adhesive layer to allow for the image sensor controller and the image sensor to be in electrical communication with one another.
