The first semiconductor die defines a first active surface including at least one conductive bond pad. The second semiconductor die defines a second active surface including at least one conductive bond pad. The intermediate substrate is positioned between the first active surface of the first semiconductor die and the second active surface of the second semiconductor die such that a first surface of the intermediate substrate faces the first active surface and such that a second surface of the intermediate substrate faces the second active surface. The first semiconductor die is electrically coupled to the intermediate substrate by at least one topographic contact extending from the first active surface to the first surface of the intermediate substrate. The intermediate substrate defines a passage there through.

Abstract: A technique is provided for installing circuit components, such as memory devices, in a support, such as a socket. The device to be installed is supported in a holder or shell. The holder is positioned over a support region in the receiving socket. A manual actuator is pressed into the holder to eject the device from the holder and to install the device in the support. The holder may be configured to hold a single device, or multiple devices aligned in slots defined by partitions. A multi-device tray may be provided for indexing devices toward an ejection slot, through which the devices are installed by manual actuation of an ejecting actuator. The technique provides protection for the device prior to and during installation, and facilitates manual installation of such devices without requiring direct hand contact with the device either prior to or during installation.

Abstract: A semiconductor die includes a metal layer deposited thereon for enhancing adhesion between the die and a mold compound package. The metal layer is substantially oxide free. The die is coated with a layer or layers of copper (Cu) and/or palladium (Pd) by electroplating or electroless coating techniques. The metal layer provides a uniform wetting surface for better adhesion of the die with the mold compound packaging during encapsulation. The increased adhesion reduces the delamination potential of the die from the package.

Abstract: A semiconductor package includes a substrate and a semiconductor die wire bonded, or alternately flip chip bonded, to the substrate. The substrate includes three separate layers including a conductive layer having a pattern of conductive traces, a first insulating layer covering the conductive traces, and a second insulating layer covering the die. The insulating layers also include planar surfaces having external contacts, and conductive vias in electrical communication with the external contacts and with the conductive traces. The external contacts have matching patterns, such that the package can be stacked on a substantially identical package to form a stacked electronic assembly. In addition, the packages in the stacked assembly can have different circuit configurations, and can perform different functions in the assembly.
