Abstract:
A semiconductor device is made by providing an integrated passive device (IPD). Through-silicon vias (TSVs) are formed in the IPD. A capacitor is formed over a surface of the IPD by depositing a first metal layer over the IPD, depositing a resistive layer over the first metal layer, depositing a dielectric layer over the first metal layer, and depositing a second metal layer over the resistive and dielectric layers. The first metal layer and the resistive layer are electrically connected to form a resistor and the first metal layer forms a first inductor. A wafer supporter is mounted over the IPD using an adhesive material and a third metal layer is deposited over the IPD. The third metal layer forms a second inductor that is electrically connected to the capacitor and the resistor by the TSVs of the IPD. An interconnect structure is connected to the IPD.
