  • Publication number: 20230116208
    Abstract: A method of manufacturing a semiconductor device includes a trench forming step, a laser irradiation step and a peeling step. In the trench forming step, a trench is formed on a first main surface of a semiconductor substrate having a device structure formed thereon. In the laser irradiation step, a laser is irradiated from a second main surface of the semiconductor substrate to a plane surface that is positioned and extends at a predetermined depth of the semiconductor substrate. In the peeling step, a device layer is peeled off from the semiconductor substrate along the plane surface on which the laser is irradiated. The peeling step may be performed in a state in which the trenches are either unfilled or filled with a material having a lower coefficient of thermal expansion than the semiconductor substrate.

  • Patent number: 8775886
    Abstract: The self-healing system comprises a self-healing processor and an error mitigation system. The self-healing processor includes a code block associated with the operation of a portion of digital logic. The self-healing processor also includes a dynamic signature analysis circuit. The processor executes the code block. The dynamic signature analysis circuit creates a dynamic signature representing the operation of the portion of digital logic associated with the code block. The error mitigation system receives the dynamic signature from the dynamic signature analysis circuit. The error mitigation system compares the dynamic signature to a static signature to determine if the signatures match. If the signatures do not match, then the digital logic associated with the code block has an error. The error mitigation system retries execution of the code block. The error mitigation system stores log information describing the above events.

    Abstract: A vacuum switchgear system for a three phase electric power system, wherein a switchgear comprises a vacuum switch comprising a vacuum container and switches accommodated in the vacuum switch and an operation unit. Each of the switches and each of the operation units is coaxially connected with an operating rod of each of the switches. A link mechanism of the operation unit is connected with a link of the adjoining operation units of the switchgears. Each of the link mechanisms transmits a force of the driving rod assisted by an electro-magnet to the adjoining driving rods through the link mechanisms so that the operation units and the switches in the same phase and the same vacuum container are operated in synchronism in response to a switch-on signal or a switch-off signal.
