  • Patent number: 7235413
    Abstract: Any damage inflicted on test pads, inter-layer insulating films, semiconductor elements or wiring at the time of electrical inspection of semiconductor integrated circuit devices is to be reduced. Reinforcements having a substantially equal linear expansion ratio (coefficient of thermal expansion) relative to a wafer to be inspected are formed over an upper face of a thin film probe, grooves are cut in the reinforcements above the probes, a first elastomer which is softer than a second elastomer is so arranged as to fill the grooves and overflow the grooves by a prescribed quantity, a glass epoxy substrate, which is a multi-layered wiring board, is fitted over the second elastomer, and pads provided over an upper face of the glass epoxy substrate and bonding pads which are part of wirings belonging to the thin film probe are electrically connected by wires.

  • Patent number: 7180158
    Abstract: A semiconductor component and method of manufacture, including an insulated gate bipolar transistor (IGBT) (100) including a semiconductor substrate (110) having a first conductivity type and buried semiconductor region (115) having a second conductivity type located above the semiconductor substrate. The IGBT further includes a plurality of first semiconductor regions (120) having the first conductivity type, a plurality of second semiconductor regions (130) having the first conductivity type, and a plurality of third semiconductor regions (140) having the second conductivity type. A sinker region (142) having the second conductivity type is disposed in a third semiconductor region and a first semiconductor region during manufacture to define the plurality of regions and tie the buried semiconductor region to the plurality of third semiconductor regions.

  • Patent number: 7179708
    Abstract: A process for fabricating non-volatile memory by tilt-angle ion implantation comprises essentially the steps of implanting sideling within a nitride dielectric layer heterogeneous elements such as, for example, Ge, Si, N2, O2, and the like, for forming traps capable of capturing more electrons within the nitride dielectric layer such that electrons can be prevented from binding together as the operation time increased; etching off both ends of the original upper and underlying oxide layers to reduce the structural destruction caused by the implantation of heterogeneous elements; and finally, depositing an oxide gate interstitial wall to eradicate electron loss and hence promote the reliability of the device.

  • Patent number: 7126151
    Abstract: An integrated circuit chip includes a formation of integrated layers configured to define at least one integrated electronic component. The integrated layers further define an integrated electron tunneling device, which includes first and second non-insulating layers spaced apart from one another such that a given voltage can be provided thereacross. The integrated electron tunneling device further includes an arrangement disposed between the first and second non-insulating layers and serving as a transport of electrons between and to the first and second non-insulating layers. The arrangement includes at least a first layer configured such that the transport of electrons includes, at least in part, transport by means of tunneling. The integrated electron tunneling device further includes an antenna structure connected with the first and second non-insulating layers, and the integrated electron tunneling device is electrically connected with the integrated electronic component.
