摘要:
A flip chip semiconductor device has a substrate with a plurality of active devices formed thereon. A passive device is formed on the substrate by depositing a first conductive layer over the substrate, depositing an insulating layer over the first conductive layer, and depositing a second conductive layer over the insulating layer. The passive device is a metal-insulator-metal capacitor. The deposition of the insulating layer and first and second conductive layers is performed without photolithography. An under bump metallization (UBM) layer is formed on the substrate in electrical contact with the plurality of active devices. A solder bump is formed over the UBM layer. The passive device can also be a resistor by depositing a resistive layer over the first conductive layer and depositing a third conductive layer over the resistive layer. The passive device electrically contacts the solder bump.

摘要:
A semiconductor device has a substrate with an inductor formed on its surface. First and second contact pads are formed on the substrate. A passivation layer is formed over the substrate and first and second contact pads. A protective layer is formed over the passivation layer. The protective layer is removed over the first contact pad, but not from the second contact pad. A conductive layer is formed over the first contact pad. The conductive layer is coiled on the surface of the substrate to produce inductive properties. The formation of the conductive layer involves use of a wet etchant. The second contact pad is protected from the wet etchant by the protective layer. The protective layer is removed from the second contact pad after forming the conductive layer over the first contact pad. An external connection is formed on the second contact pad.

A semiconductor device has a first conductive layer formed over a substrate. A first insulating layer is formed over the substrate and first conductive layer. A second conductive layer is formed over the first conductive layer and first insulating layer. A second insulating layer is formed over the first insulating layer and second conductive layer. The second insulating layer has a sidewall between a surface of the second insulating material and surface of the second conductive layer. A protective layer is formed over the second insulating layer and surface of the second conductive layer. The protective layer follows a contour of the surface and sidewall of the second insulating layer and second conductive layer. A bump is formed over the surface of the second conductive layer and a portion of the protective layer adjacent to the second insulating layer. The protective layer protects the second insulating layer.
摘要:
A flip chip semiconductor device has a substrate with a plurality of active devices formed thereon. A contact pad is formed on the substrate in electrical contact with the plurality of active devices. A passivation layer is formed over the substrate and intermediate conduction layer. An adhesive layer is formed over the passivation layer. A barrier layer is formed over the adhesive layer. A wetting layer is formed over the barrier layer. The barrier layer and wetting layer in a first region are removed, while the barrier layer, wetting layer, and adhesive layer in a second region are maintained. The adhesive layer over the passivation layer in the first region are maintained until the solder bumps are formed. By keeping the adhesive layer over the passivation layer until after formation of the solder bumps, less cracking occurs in the passivation layer.

摘要:
A method of manufacturing a semiconductor device includes providing a substrate with an insulation layer disposed on a top surface of the substrate, forming a passive device over the top surface of the substrate, removing the substrate, depositing an insulating polymer film layer over the insulation layer, and depositing a metal layer over the insulating polymer film layer. A solder mask can be formed over the metal layer. A conformal metal layer can then be formed over the solder mask. A notch can be formed in the insulation layer to enhance the connection between the insulating polymer film layer and the insulation layer. Additional semiconductor die can be electrically connected to the passive device. The substrate is removed by removing a first amount of the substrate using a back grind process, and then removing a second amount of the substrate using a wet dry, dry etch, or chemical-mechanical planarization process.
