  • Publication number: 20210360840
    Abstract: A noise suppression sheet comprises a non-magnetic metal layer, a plurality of metal magnetic layers, and a plurality of insulating layers, and the metal magnetic layer and the insulating layer are alternately laminated on the non-magnetic metal layer. The noise suppression sheet can absorb and suppress noise generated from a circuit or the like in an electronic component by being mounted on the electronic component or the like. In the noise suppression sheet, noise is absorbed by each of the metal magnetic layers. Noise that is transmitted without being absorbed by the metal magnetic layer can be reflected by the non-magnetic metal layer and can be absorbed again by the metal magnetic layer, and hence the noise suppression sheet can suppress noise effectively.

  • Patent number: 11101234
    Abstract: A material for Cu pillars is formed as cylindrical preforms in advance and connecting these cylindrical preforms to electrodes on a semiconductor chip to form Cu pillars. Due to this, it becomes possible to make the height/diameter ratio of the Cu pillars 2.0 or more. Since electroplating is not used, the time required for production of the Cu pillars is short and the productivity can be improved. Further, the height of the Cu pillars can be raised to 200 ?m or more, so these are also preferable for moldunderfill. The components can be freely adjusted, so it is possible to easily design the alloy components to obtain highly reliable Cu pillars.
