Abstract:
A process for partially repairing defective Multi-Chip Module (MCM) Thin-Film (TF) wiring nets. The process comprises the steps of locating a short circuit between any two nets of the MCM, identifying a site to cut in one of the two nets, and deleting an internal portion of one of the two nets at the identified site.

Abstract:
An integrated circuit chip package having an electrical contact configurable for either signal or power/ground and a method for constructing the integrated circuit chip package are disclosed. The integrated circuit chip package includes a substrate for supporting an integrated circuit chip and a dedicated conductor for supplying voltage to the integrated circuit chip. A configurable contact is attached to a surface of the substrate. The integrated circuit chip package further includes a signal connection for electrically connecting a signal connector of an integrated circuit chip and the configurable contact. A removable connector electrically connects the configurable contact and the dedicated conductor, thereby enabling the configurable contact to be configured as either a signal or power/ground contact depending upon the absence or presence of the electrical connection between the configurable contact and the dedicated conductor provided by the removable connector.
Abstract:
Apparatus, method and program product detect an attempt to tamper with a microchip by determining that an electrical path comprising one or more connections and a metal plate attached to the backside of a microchip has become disconnected or otherwise altered. A tampering attempt may also be detected in response to the presence of an electrical path that should not be present, as may result from the microchip being incorrectly reconstituted. Actual and/or deceptive paths may be automatically selected and monitored to further confound a reverse engineering attempt.

A system comprises a first integrated circuit (IC) chip that includes a first electronic component; a second IC chip that includes a second electronic component; a through silicon via (TSV) in the second IC chip that electrically couples the first electronic component to the second electronic component; and a signal gating transistor that fully occludes the TSV.
Abstract:
A semiconductor chip has a gated through silicon via (TSVG). The TSVG may be switched so that the TSVG can be made conducting or non-conducting. The semiconductor chip may be used between a lower level semiconductor chip and a higher semiconductor chip to control whether a voltage supply on the lower level semiconductor chip is connected to or disconnected from a voltage domain in the upper level semiconductor chip. The TSVG comprises an FET controlled by the lower level chip as a switch.

Abstract:
A circuit arrangement and method utilize a universal, standardized inter-layer interconnect in a multi-layer semiconductor stack to facilitate interconnection and communication between functional units disposed on a stack of semiconductor dies. Each circuit layer in the multi-layer semiconductor stack is required to include an inter-layer interface region that is disposed at substantially the same topographic location such that when the semiconductor dies upon which such circuit layers are disposed are arranged together in a stack, electrical conductors disposed within each semiconductor die are aligned with one another to provide an inter-layer bus that is oriented vertically, or transversely, with respect to the individual circuit layers. Based upon a standardized placement of the inter-layer interface region in each circuit layer, and a standardized arrangement of electrical conductors associated with the inter-layer bus, each circuit layer may designed using a standardized template upon which the design features necessary to implement the inter-layer bus are already provided, thereby simplifying circuit layer design and the interconnection of functional units to the inter-layer bus. In addition, vertically-oriented supernodes may be defined within a semiconductor stack to provide multiple independently-operating nodes having functional units disposed in multiple circuit layers of the stack.
