Abstract: A perpendicular magnetic recording medium, which includes a nonmagnetic substrate, and a soft magnetic layer, a first orientation control layer, a nonmagnetic intermediate layer, and a perpendicular magnetic recording layer formed sequentially on the nonmagnetic substrate. The perpendicular magnetic recording medium further includes a second orientation control layer provided between the first orientation control layer and the nonmagnetic intermediate layer. The nonmagnetic intermediate layer has hexagonal close-packed (hcp) structure. The first orientation control layer has a face-centered cubic (fcc) structure. The second orientation control layer includes Co and Cr, and has the hcp structure.

Abstract: The electrode of a thin-type capacitor is connected to the rear surface of a p-type semiconductor substrate which is brought to a ground potential, by a conductive DAF (Die Attach Film) or by a conductive adhesive, and the electrodes of the front surface of the p-type semiconductor substrate are respectively connected with and stacked on the terminals of a thin-type inductor by bumps, whereby manufacturing costs can be reduced while the occurrence of noise can be suppressed and packaging area can be made small.
