  • Patent number: 8637973
    Abstract: A microelectronic component package includes a plurality of electrical leads which are coupled to a microelectronic component and which have exposed lengths extending outwardly beyond a peripheral edge of an encapsulant. A plurality of terminals may be positioned proximate a terminal face of the encapsulant and these terminals may be electrically coupled to the same leads. This can facilitate connection of the microelectronic component to a substrate using the leads as a conventional leaded package. The terminals, however, can facilitate stacking of the leaded package with one or more additional microelectronic components, e.g., a BGA package.

  • Patent number: 8138617
    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.

  • Patent number: 8008126
    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.
