The invention provides an electrical contact device, a pre-assembly for producing the electrical contact device, and a method of forming the electrical contact device. The electrical contact device includes a plurality of fine pitch electrical leads disposed in parallel spaced apart relation. An insulating member encapsulates portions of the electrical leads which extend from opposite sides of the insulating member. The insulating member retains the electrical leads in position and electrically isolated from one another. The contact device is used to facilitate connection with the leads of an IC package.
Abstract:
A BGA package and a method for fabricating the package are provided. The package includes a semiconductor die, internal conductors wire bonded to bond pads on the die, external ball contacts attached to ball bonding pads formed on the conductors in a dense grid pattern, and an encapsulating resin encapsulating the die and conductors. The package is fabricated using a lead frame having lead fingers that form the conductors. The die is back bonded to a polymer tape placed across the lead fingers, and then wire bonded to bonding pads on the conductors. In addition, the encapsulating resin is molded to include openings for the ball contacts which are aligned with the ball bonding pads. An alternate embodiment BGA package includes a polymer substrate adhesively bonded to a face of the die. The polymer substrate includes conductors having beam leads aligned with an opening through the polymer substrate. The opening provides access for a bonding tool for bonding bumps on the beam leads to bond pads on the die.
Abstract:
An interconnect for BGA packages, a BGA package fabricated using the interconnect, and a method for fabricating BGA packages using the interconnect, are provided. The interconnect includes multiple polymer substrates on which patterns of conductors are formed. Each substrate can be used to fabricate a BGA package. The conductors on the substrates include end portions having bonding vias formed therethrough in alignment with access openings in the substrates. During fabrication of the BGA packages, the bonding vias allow the conductors to be bonded to bond pads on semiconductor dice by forming metal bumps on the bonding vias and bond pads. The access openings in the substrates provide access to the bonding vias and bond pads for a bonding tool configured to form the metal bumps. In addition to the bonding vias, the conductors include ball bonding pads configured for attaching ball contacts, such as solder balls, to the conductors and substrates. The completed BGA package includes a substrate adhesively bonded to a semiconductor die; conductors with bonding vias on the substrate; metal bumps in the bonding vias bonding the conductors to bond pads on the die; and an area array of ball contacts attached to the conductors and substrate.

A semiconductor package includes a substrate, and a semiconductor die flip chip mounted to the substrate. The package also includes substrate circuitry on a circuit side of the substrate, die circuitry on a back side of the die, terminal contacts on the die circuitry, bonded connections between the substrate circuitry and the die circuitry, and an encapsulant on the bonded connections and edges of the die. The die can include an image sensor on the circuit side configured to receive electromagnetic radiation transmitted through the substrate. A method for fabricating the package includes the step of providing a wafer with multiple dice, forming the die circuitry on the dice, and simulating the wafer into individual dice. The method also includes the steps of providing a substrate panel with multiple substrates, forming the substrate circuitry on the substrates, flip chip bonding the dice to the substrates, forming bonded connections between the dice and the substrates, forming the terminal contacts on the die circuitry, and singulating the panel into separate components.
Abstract:
A method is provided for installing circuit components, such as memory devices, in a support, such as a socket. The device to be installed is supported in a holder or shell. The holder is positioned over a support region in the receiving socket. A manual actuator is pressed into the holder to eject the device from the holder and to install the device in the support. The holder may be configured to hold a single device, or multiple devices aligned in slots defined by partitions. A multi-device tray may be provided for indexing devices toward an ejection slot, through which the devices are installed by manual actuation of an ejecting actuator. The technique provides protection for the device prior to and during installation, and facilitates manual installation of such devices without requiring direct hand contact with the device either prior to or during installation.
