  • Publication number: 20070272961
    Abstract: Disclosed is a semiconductor structure that incorporates a capacitor for reducing the soft error rate of a device within the structure. The multi-layer semiconductor structure includes an insulator-filled deep trench isolation structure that is formed through an active silicon layer, a first insulator layer, and a first bulk layer and extends to a second insulator layer. The resulting isolated portion of the first bulk layer defines the first capacitor plate. A portion of the second insulator layer that is adjacent the first capacitor plate functions as the capacitor dielectric. Either the silicon substrate or a portion of a second bulk layer that is isolated by a third insulator layer and another deep trench isolation structure can function as the second capacitor plate. A first capacitor contact couples, either directly or via a wire array, the first capacitor plate to a circuit node of the device in order to increase the critical charge, Qcrit, of the circuit node.

  • Publication number: 20070195841
    Abstract: A method for neutralizing trapped charges in a buried oxide layer. The method includes providing a semiconductor structure which includes (a) a semiconductor layer, (b) a charge accumulation layer on top of the semiconductor layer, and (c) a doped region in direct physical contact with the semiconductor layer, wherein the charge accumulation layer comprises trapped charges of a first sign, and wherein the doped region and the semiconductor layer form a P-N junction diode. Next, free charges are generated in the P-N junction diode, wherein the free charges are of a second sign opposite to the first sign. Next, the free charges are accelerated towards the charge accumulation layer, resulting in some of the free charges entering the charge accumulation layer and neutralizing some of the trapped charges in the charge accumulation layer.

  • Publication number: 20060226142
    Abstract: An electronic structure having wiring, and an associated method of designing the structure, for limiting a temperature gradient in the wiring. The electronic structure includes a substrate having a layer that includes a first and second wire which do not physically touch each other. The first and second wires are adapted to be at an elevated temperature due to Joule heating in relation to electrical current density in the first and second wires. The first wire is electrically and thermally coupled to the second wire by an electrically and thermally conductive structure that exists outside of the layer. The width of the second wire is tailored so as to limit a temperature gradient in the first wire to be below a threshold value that is predetermined to be sufficiently small so as to substantially mitigate adverse effects of electromigration in the first wire.

  • Publication number: 20060163685
    Abstract: A thermo-mechanical cleavable structure is provided and may be used as a programmable fuse for integrated circuits. As applied to a programmable fuse, the thermo-mechanical cleavable structure includes an electrically conductive cleavable layer adjacent to a thermo-mechanical stressor. As electricity is passed through the cleavable layer, the cleavable layer and the thermo-mechanical stressor are heated and gas evolves from the thermo-mechanical stressor. The gas locally insulates the thermo-mechanical stressor, causing local melting adjacent to the bubbles in the thermo-mechanical stressor and the cleavable structure forming cleaving sites. The melting also interrupts the current flow through the cleavable structure so the cleavable structure cools and contracts. The thermo-mechanical stressor also contracts due to a phase change caused by the evolution of gas therefrom. As the thermo-mechanical cleavable structure cools, the cleaving sites expand causing gaps to be permanently formed therein.

  • Publication number: 20060103007
    Abstract: A structure and associated method for annealing a trapped charge from a semiconductor device. The semiconductor structure comprises a substrate and a first heating element. The substrate comprises a bulk layer, an insulator layer and a device layer. The first heating element is formed within the bulk layer. A first side of the first heating element is adjacent to a first portion of the insulator layer. The first heating element is adapted to be selectively activated to generate thermal energy to heat the first portion of the insulator layer and anneal a trapped electrical charge from the first portion of the insulator layer.

  • Publication number: 20050184720
    Abstract: A method and system for predicting gate reliability. The method comprises the steps of stressing a gate dielectric test site to obtain gate dielectric test site data and using the test site data to predict gate reliability. Preferably, the test structure and the product structure are integrated in such a manner that a test site occupies some of the product area and the product itself occupies the remainder of the product area.
