  • Patent number: 7952211
    Abstract: One or more electronic components can be mounted on the back side of a semiconductor die. The components can be passive components, active components, or combinations thereof. The components can be soldered to signal routes on the back side of the die, the signal routes being attached to the die using a metallization layer or using one or more dielectric layer sections. Placing components on the back side of the die can allow for incorporation of the components without necessarily increasing the form factor of the die's package.

  • Publication number: 20110121449
    Abstract: A semiconductor device has a stress relief buffer mounted to a temporary substrate in locations designated for bump formation. The stress relief buffer can be a multi-layer composite material such as a first compliant layer, a silicon layer formed over the first compliant layer, and a second compliant layer formed over the silicon layer. A semiconductor die is also mounted to the temporary substrate. The stress relief buffer can be thinner than the semiconductor die. An encapsulant is deposited between the semiconductor die and stress relief buffer. The temporary substrate is removed. An interconnect structure is formed over the semiconductor die, encapsulant, and stress relief buffer. The interconnect structure is electrically connected to the semiconductor die. A stiffener layer can be formed over the stress relief buffer and encapsulant. A circuit layer containing active devices, passive devices, conductive layers, and dielectric layers can be formed within the stress relief buffer.

  • Patent number: 7923295
    Abstract: A semiconductor device is made by forming a photoresist layer over a metal carrier. A plurality of openings is formed in the photoresist layer extending to the metal carrier. A conductive material is selectively plated in the openings of the photoresist layer using the metal carrier as an electroplating current path to form wettable contact pads. A semiconductor die has bumps formed on its surface. The bumps are directly mounted to the wettable contact pads to align the die with respect to the wettable contact pads. An encapsulant is deposited over the die. The metal carrier is removed. An interconnect structure is formed over the encapsulant and electrically connected to the wettable contact pads. A plurality of conductive vias is formed through the encapsulant and extends to the contact pads. The conductive vias are aligned by the wettable contact pads with respect to the die to reduce interconnect pitch.
