  • Publication number: 20220239165
    Abstract: An antenna is provided in one device from among a power transmission device and a power reception device. A transmission circuit drives the antenna. A plurality of antennas is provided in the other device from among the power transmission device and the power reception device. A radio wave detection circuit detects intensity of a radio wave received by the plurality of antennas. A position detector detects a relative position between the power transmission coil and the power reception coil, based on the intensity detected by the radio wave detection circuit. A transmission circuit drives at least one antenna. The radio wave detection circuit detects intensity of a radio wave being transmitted from an antenna driven by the transmission circuit and being received by an antenna other than the antenna driven by the transmission circuit.

  • Publication number: 20210391759
    Abstract: Provided is a position detection system capable of detecting a position with high accuracy when position detection is performed using an antenna on a transmission side and an antenna on a reception side. In the position detection system, at least one of a transmission antenna and a reception antenna is a multi-axis antenna including a first winding portion formed by winding a first conducting wire and a second winding portion formed by winding a second conducting wire. An axial direction of a first winding axis of the first winding portion and an axial direction of a second winding axis of the second winding portion are two directions different from each other. The first winding portion and the second winding portion are electrically connected to each other.

  • Patent number: 10273386
    Abstract: Provided are a thermosetting adhesive sheet and a method for manufacturing a semiconductor device capable of reducing semiconductor wafer warping and chipping. The thermosetting adhesive sheet includes a thermosetting adhesive layer containing a resin component and a filler, the resin component containing a (meth)acrylate and a polymerization initiator, the (meth)acrylate containing a solid (meth)acrylate and a trifunctional or higher functional (meth)acrylate, content of the solid (meth)acrylate in the resin component being 55 wt % or more; a total value obtained by multiplying the number of functional groups per unit molecular weight of the (meth)acrylate by content of the (meth)acrylate in the resin component being 2.7E-03 or more, and blending amount of the filler being 80 to 220 pts. mass with respect to 100 pts. mass of the resin component.

  • Patent number: 10192769
    Abstract: A thermosetting adhesive sheet and a method for manufacturing a semiconductor device capable of reducing warping of a semiconductor wafer are provided. The thermosetting adhesive sheet is to be applied to a grinding-side surface of a semiconductor wafer and cured before dicing and includes a polymer containing an elastomer, a (meth) acrylate containing more than 95% wt of a polyfunctional (meth) acrylate with respect to total (meth)acrylate content, an organic peroxide having a one-minute half-life temperature of 130° C. or lower, and a transparent filler. Thereby, the thermosetting adhesive sheet significantly shrinks and generates a stress opposing a warp direction of the semiconductor wafer, enabling the semiconductor wafer to be maintained in a flat state.
