摘要:
An integrated circuit system provides a precursor for an integrated wire bond and flip chip structure. The precursor has a plurality of contact pads thereon. A layer of titanium is deposited on the precursor. A layer of nickel-vanadium is deposited on the layer of titanium. A layer of copper is deposited on the layer of nickel-vanadium. A mask is formed on at least a portion of the layer of copper. Portions of the layers of copper and nickel-vanadium not protected by the mask are removed to expose portions of the layer of titanium. The exposed portions of the layer of titanium are etched with an etching solution consisting of an etchant, a viscosity modifier, and an oxidizer.

摘要:
A semiconductor device is made by providing a temporary carrier for supporting the semiconductor device. An integrated passive device (IPD) is mounted to the temporary carrier using an adhesive. The IPD includes a capacitor and a resistor and has a plurality of through-silicon vias (TSVs). A discrete component is mounted to the temporary carrier using the adhesive. The discrete component includes a capacitor. The IPD and the discrete component are encapsulated using a molding compound. A first metal layer is formed over the molding compound. The first metal layer is connected to the TSVs of the IPD and forms an inductor. The temporary carrier and the adhesive are removed, and a second metal layer is formed over the IPD and the discrete component. The second metal layer interconnects the IPD and the discrete component and forms an inductor. An optional interconnect structure is formed over the second metal layer.

A semiconductor device has a first conductive layer formed over a sacrificial substrate. A first integrated passive device (IPD) is formed in a first region over the first conductive layer. A conductive pillar is formed over the first conductive layer. A high-resistivity encapsulant greater than 1.0 kohm-cm is formed over the first IPD to a top surface of the conductive pillar. A second IPD is formed over the encapsulant. The first encapsulant has a thickness of at least 50 micrometers to vertically separate the first and second IPDs. An insulating layer is formed over the second IPD. The sacrificial substrate is removed and a second semiconductor die is disposed on the first conductive layer. A first semiconductor die is formed in a second region over the substrate. A second encapsulant is formed over the second semiconductor die and a thermally conductive layer is formed over the second encapsulant.

摘要:
A semiconductor device is made with a conductive via formed through a top-side of the substrate. The conductive via extends vertically through less than a thickness of the substrate. An integrated passive device (IPD) is formed over the substrate. A plurality of first conductive pillars is formed over the first IPD. A first semiconductor die is mounted over the substrate. An encapsulant is formed around the first conductive pillars and first semiconductor die. A second IPD is formed over the encapsulant. An interconnect structure is formed over the second IPD. The interconnect structure operates as a heat sink. A portion of a back-side of the substrate is removed to expose the first conductive via. A second semiconductor die is mounted to the back-side of the substrate. The second semiconductor die is electrically connected to the first IPD and first semiconductor die through the conductive via.
