A semiconductor package has a first semiconductor die mounted on a substrate. A conductive via is formed through the substrate. A first RDL is formed on a first surface of the substrate in electrical contact with the conductive via and the first semiconductor die. A second RDL is formed on a second surface of the substrate opposite the first surface of the substrate die in electrical contact with the conductive via. A second semiconductor die can be mounted on the substrate and electrically connected to the second RDL. Bonding pads are formed over the first and second surfaces of the substrate in electrical contact with the first and second RDLs, respectively. The bonding pads on opposite surfaces of the substrate are aligned. Solder bumps or bond wires can be formed on the bonding pads. The semiconductor packages can be stacked and electrically connected through the aligned bonding pads.

A method of manufacturing a semiconductor package involves providing a substrate having a window. The substrate may include a leadframe having half-etched leads. First and second semiconductor devices are mounted to a top surface of the substrate on either side of the window using an adhesive. A third semiconductor device is mounted to the first and second semiconductor devices using an adhesive. The third semiconductor device is disposed over the window of the substrate. A wirebond or other electrical interconnect is formed between the third semiconductor device and a contact pad formed over a bottom surface of the substrate opposite the top surface of the substrate. The wirebond or other electrical interconnect passes through the window of the substrate. An encapsulant is deposited over the first, second, and third semiconductor devices.

A semiconductor device has a base substrate with first and second opposing surfaces. A plurality of cavities and base leads between the cavities is formed in the first surface of the base substrate. The first set of base leads can have a different height or similar height as the second set of base leads. A concave capture pad can be formed over the second set of base leads. Alternatively, a plurality of openings can be formed in the base substrate and the semiconductor die mounted to the openings. A semiconductor die is mounted between a first set of the base leads and over a second set of the base leads. An encapsulant is deposited over the die and base substrate. A portion of the second surface of the base substrate is removed to separate the base leads. An interconnect structure is formed over the encapsulant and base leads.
摘要:
A semiconductor device is made by forming solder bumps on a first side of a semiconductor wafer. A protective layer is formed on a second side of the semiconductor wafer opposite the first side. The protective layer can be adhesive paste, laminated film, spin-coated resin, epoxy based elastomer, organic rubbery material, polystyrene, polyethylene terephthalate, or other polymer material. The semiconductor wafer is singulated into semiconductor die. The semiconductor die is mounted to a carrier. A molding compound is formed around the semiconductor die. The protective layer provides stress relief for the semiconductor die. The protective layer is removed from the semiconductor die. The protective layer can provide a thermal dissipation, in which case it is made with metal or polymer-based material with a filler such as alumina, zinc oxide, silicon dioxide, silver, aluminum, and aluminum nitride.

A semiconductor device has a carrier with a die attach area. Recesses are formed partially through the carrier outside the die attach area. A first conductive layer is conformally applied over a surface of the carrier and into the recesses. A semiconductor die is mounted to the die attach area of the carrier. An encapsulant is deposited over the carrier and semiconductor die. The encapsulant extends into the recesses over the first conductive layer to form encapsulant bumps. The carrier is removed to expose the first conductive layer over the encapsulant bumps. A first insulating layer is formed over the semiconductor die with openings to expose contact pads of the semiconductor die. A second conductive layer is formed between the first conductive layer and the contact pads on the semiconductor die. A second insulating layer is formed over the second conductive layer and semiconductor die.

A semiconductor device is made by providing a semiconductor die having an optically active area, providing a leadframe or pre-molded laminated substrate having a plurality of contact pads and a light transmitting material disposed between the contact pads, attaching the semiconductor die to the leadframe so that the optically active area is aligned with the light transmitting material to provide a light transmission path to the optically active area, and disposing an underfill material between the semiconductor die and leadframe. The light transmitting material includes an elevated area to prevent the underfill material from blocking the light transmission path. The elevated area includes a dam surrounding the light transmission path, an adhesive ring, or the light transmission path itself can be the elevated area. An adhesive ring can be disposed on the dam. A filler material can be disposed between the light transmitting material and contact pads.
