    Abstract: There is provided an electromagnetic wave absorber in which uniformity, reproducibility and productivity are raised by forming a metal soft magnetic material flat plate, the surface of which is smoothed, of a regular shape disk or elliptical shape easily, at low cost, stably and certainly. In the electromagnetic wave absorber composed of a mixture of a magnetic material particle 21 and an organic binding material, the magnetic material particle 21 is constituted by a nucleus 22 made of organic material and a magnetic material film 23 formed on its surface.

    Abstract: A resin component for encapsulating a semiconductor includes magnetic powder and silica powder whose average particle diameter is smaller than the average particle diameter of the magnetic powder. Thus, the curing body of the resin component for encapsulating a semiconductor has an electromagnetic wave shielding function by the magnetic powder. Since the spaces of the magnetic powder are filled with the silica powder whose average particle diameter is small, the moldability of the curing body is improved and the insulating characteristics thereof are enhanced. Such a resin component for encapsulating a semiconductor is employed, there can be produced a preferably formed and encapsulated semiconductor device having the electromagnetic wave shielding function and having no malfunction generated due to leakage current from a semiconductor element.

    Abstract: A semiconductor element is mounted on a wiring circuit board in which a circuit has been formed. This semiconductor element is resin-encapsulated with a first encapsulating resin layer. Then, a second encapsulating resin layer is formed, on the outer circumference of the first encapsulating resin layer, from an epoxy resin composition containing the following components (A) to (D): (A)epoxy resin; (B)phenolic resin; (C)curing accelerator; and (D)at least one of the following particles (d1) and (d2): (d1) conductive particles whose surfaces are subjected to coating treatment with an insulating inorganic material; and (d2) magnetic particles whose surfaces are subjected to coating treatment with an insulating inorganic material.
