  • Publication number: 20080067675
    Abstract: Systems and methods for packaging integrated circuit chips in castellation wafer level packaging are provided. The active circuit areas of the chips are coupled to castellation blocks and, depending on the embodiment, input/output pads. The castellation blocks and input/output pads are encapsulated and held in place by an encapsulant. When the devices are being fabricated, the castellation blocks and input/output pads are sawed through. If necessary, the wafer portion on which the devices are fabricated may be thinned. The packages may be used as a leadless chip carrier package or may be stacked on top of one another. When stacked, the respective contacts of the packages are preferably coupled. Data may be written to, and received from, packaged chips when a chip is activated. Chips may be activated by applying the appropriate signal or signals to the appropriate contact or contacts.

  • Publication number: 20080054423
    Abstract: Methods for forming an edge contact on a die and edge contact structures are described. The edge contacts on the die do not increase the height of the die. The edge contacts are positioned on the periphery of a die. The edge contacts are positioned in the saw streets. Each edge contact is connected to one bond pad of each die adjacent the saw street. The edge contact is divided into contacts for each adjacent die when the dies are separated. In an embodiment, a recess is formed in the saw street. In an embodiment, the recess is formed by scribing the saw street with a mechanical cutter. The recess is patterned and contact material is deposited to form the edge contacts.

  • Publication number: 20060208350
    Abstract: A support structure for a semiconductor device with peripherally disposed contacts includes a support substrate and at least one conductive column protruding from the support substrate. The at least one conductive column is configured to contact an outer connector on a peripheral edge of a semiconductor device that may be carried by the support structure. Optionally, the at least one conductive column may engage a feature of (e.g., a recess in) the peripherally disposed outer connector. The at least one conductive column may facilitate alignment of one or more semiconductor devices with the support substrate alignment of semiconductor devices relative to one another, or electrical connection between multiple semiconductor devices of other components.

  • Publication number: 20060208351
    Abstract: A semiconductor device package includes outer connectors that are located along at least one peripheral edge thereof and that extend substantially across the height of the peripheral edge. Each outer connector is formed by forming a conductive via that extends substantially through a substrate blank and laterally across a street located adjacent to an outer periphery of at least one semiconductor device. Upon severing the substrate along the street and through the conductive via, at least one outer connector is formed at an outer edge of the semiconductor device. An outer connector may include a recess that at least partially receives a conductive column protruding from a support substrate. Assemblies may include the packages in stacked arrangement, without height-adding connectors.
