  • Radio wave absorber
    Patent number: 11539141
    Abstract: A radio wave absorber includes a base member, and a radio wave absorption film formed on the base member. The radio wave absorption film includes at least MTC-substituted ?-Fe2O3 and black titanium oxide. The MTC-substituted ?-Fe2O3 is a crystal belonging to the same space group as an ?-Fe2O3 crystal and expressed by ?-MxTiyCoyFe2?2y?xO3 where M is at least one element selected from the group consisting of Ga, In, Al, and Rh, 0<x<1, and 0<y<1.
    Type: Grant

  • DEVICE MOUNTING BOARD AND MANUFACTURING METHOD THEREFOR, AND SEMICONDUCTOR MODULE
    Publication number: 20090194322
    Abstract: A device mounting board has a double-layer wiring structure where a first wiring layer and a second wiring layer are stacked together with an insulating layer held between the first and second wiring layers. The first wiring layer and the second wiring layer are electrically connected by way of a via conductor provided on a side wall of a through-hole that penetrates the insulating layer. The through-hole that penetrates the insulating layer has a stepped portion. The via conductor, provided along the insulating layer in the via conductor, has a step associated with the stepped portion of the via conductor.
