Abstract
Abstract A stabilized power supply device includes a substrate and a passive part laminate layered on the substrate. The passive part laminate, shaped as a single flat board, includes a thin charge storage film element. A thin magnetic inductive film element is laminated on the thin charge storage film element. The device also includes an active part incorporated in a flip chip. The flip chip, including semiconductors and bump electrodes, is mounted on an upper surface of the passive part laminate. The upper surface of the passive part laminate includes terminals for connecting the passive part laminate to the bump electrodes. This connection also fixes the active part to the passive part laminate.
