  • 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.

  • Patent number: 5046567
    Abstract: A method and apparatus for achieving adiabatic heat ignition of combustible material, particularly explosive compositions which involves entrapping a quantity of gas in a chamber which is in communication with the combustible material and suddenly compressing the gas to the extent that the temperature thereof is increased adiabatically to the ignition temperature of the combustible material. The apparatus is particularly adaptable for use as an adiabatic ignition device for detonating cord and shaped charges of perforating guns for completion of wells. A quantity of high explosive within an explosive barrel is in detonating proximity with the detonating cord. A cylinder forms an air chamber which is in communication with the explosive composition and is provided with a piston for compression of the gas. One or more shear pins or other locking devices are provided to secure the piston in immovable relation with the cylinder.
