摘要:
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.
摘要:
A method and structures are provided for implementing semiconductor signal-capable capacitors with deep trench and Through-Silicon-Via (TSV) technologies. A deep trench N-well structure is formed and an implant is provided in the deep trench N-well structure with a TSV formed in a semiconductor chip. At least one angled implant is created around the TSV in a semiconductor chip. The TSV is surrounded with a dielectric layer and filled with a conducting material which forms one electrode of the capacitor. A connection is made to one implant forming a second electrode to the capacitor.
摘要:
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.
摘要:
A field-effect transistor has a gate, a source, and a drain. The gate has a via extending through a semiconductor chip substrate from one surface to an opposite surface of the semiconductor chip substrate. The source has a first toroid of ion dopants implanted in the semiconductor chip substrate surrounding one end of the via on the one surface of the semiconductor chip substrate. The drain has a second toroid of ion dopants implanted in the semiconductor chip substrate surrounding an opposite end of the via on the opposite surface of the semiconductor chip substrate.
摘要:
An integrated circuit assembly comprising a microchip that shares an interdependent function with a second, stacked microchip. Alternation of the physical arrangement or functionality of the microchips may initiate a defense action intended to protect security sensitive circuitry associated with one of the microchips. The microchips may communicate using through-silicon vias or other interconnects.
摘要:
An integrated circuit assembly and associated method of detecting microchip tampering may include multiple connections in electrical communication with a conductive layer. Defensive circuitry may inhibit analysis of the microchip where a connection no longer connects to the conductive layer. The defensive circuitry may similarly be initiated where a connection unintended to be in electrical communication with the conductive layer is nonetheless connected.
摘要:
A method and apparatus include conductive material doped within a microchip that accumulates a detectable charge in the presence of ions. Such ions may result from a focused ion beam or other unwelcome technology exploitation effort. Circuitry sensing the charge buildup in the embedded, doped material may initiate a defensive action intended to defeat the tampering operation.
