The magnetic material layers are layers of a magnetic material having multiple metal grains constituted by a Fe—Si-M soft magnetic alloy and oxide film formed on the surface of the metal grains. The magnetic material has bonding portions where adjacent metal grains are bonded via the oxide film formed on the respective surfaces of the adjacent metal grains as well as bonding portions of metal grains bonding to each other in areas where no oxide film is present, and at least some of the voids generated by agglomeration of the metal grains are filled with a resin material.

摘要： In characteristic test measurements of double-gate-in-trench p-channel power MOSFETs each having a p+ polysilicon gate electrode and a p+ field plate electrode in a trench, which were fabricated according to common design techniques, it has been found that, under conditions where a negative gate bias is applied continuously at high temperature with respect to the substrate, an absolute value of threshold voltage tends to increase steeply after the lapse of a certain period of stress application time. To solve this problem, the present invention provides a p-channel power MOSFET having an n-type polysilicon linear field plate electrode and an n-type polysilicon linear gate electrode in each trench part thereof.
