  • Patent number: 7932596
    Abstract: A method and apparatus for making a package having improved heat conduction characteristics and high frequency response. A relatively thick package substrate, such as copper, has a wiring layer bonded to one face, leaving the opposite face exposed, for example, to be a surface for connection to a heat sink. One or more chips are bonded to the wiring layer, and an array of connectors, such as solder balls are provided around the periphery of the chip(s) for connection to a printed circuit board. In some embodiments, the printed circuit board has a hole that the chip(s) extend into to allow smaller external-connection solder balls. In some embodiments, a second heat sink is connected to the back of the chip through the PCB hole.

  • Patent number: 7794236
    Abstract: An LGA socket for receiving substrate packages of various sizes and a method of fabricating the socket. In an embodiment, the socket has a planar surface for seating a substrate package. Socket contacts are disposed on the planar surface in a layout common to the layout of interconnects formed on the bottom of substrate packages the socket is designed to receive. A plurality of socket locating features is formed on the socket body to prevent lateral displacement of a reference substrate package. A corresponding number of package locating features are formed on the substrate body of packages larger than the reference substrate package. Each of the socket locating features meshes with the corresponding package locating feature of the larger package.

  • Patent number: 7656035
    Abstract: In one embodiment, the invention provides a method comprising fabricating a die bump on a die, the die bump being shaped and dimensioned to at least reduce the flow of solder material used, to attach the die bump to a package substrate, towards an under bump metallurgy (UBM) layer located below the die bump. Advantageously, the method may comprise performing a substrate reflow operation to attach the package substrate to the die bump, without performing a separate wafer reflow operation to reflow the die bump.

  • Patent number: 7199304
    Abstract: Apparatus and methods are provided to enable circuit configuration of a substrate by the setting of settable bits associated with those circuits. An electrically conductive material is deposited onto selected settable bits which closes the desired circuit between the settable bits. In one embodiment in accordance with the invention, a carrier substrate is provided that comprises settable bits which are used to control a microelectronic package's electrical characteristics. In one embodiment, the settable bits are in the form of sets of spaced-apart bit pads which form an open circuit between a logic circuit and electrical ground (Vss). The open circuit is closed with the application of electrically conductive material that bridges the set of spaced-apart bit pads. The settable bits, therefore, do not require the addition of high profile components such as 0-ohm resisters to form the electrical bridging function between the bit pads of a settable bit.
