  • Patent number: 9536805
    Abstract: A hybrid package having a processor module disposed on a substrate and an auxiliary module disposed on a patterned lid. The auxiliary module may be a memory module, a power management integrated circuit (PMIC) module, and/or other suitable module, that are located in the package along with the processor module. Having the auxiliary module in the package with the processor module reduces the noise at the solder bump between the processor module and the substrate. Having the auxiliary module in the package with the processor module also allows other modules to be added to the package without increasing the area of the package.

  • Patent number: 6812576
    Abstract: An interconnect via structure according to the present invention can be used to support high frequency broadband signal transmission. The interconnect vias progressively increase in size and pitch from the signal source layer of the package substrate to the terminal pad layer of the package substrate. Each interconnect via includes a plurality of conductive sections formed at different substrate layers. At each substrate layer, the size and pitch of the vias result in a specified impedance. In a practical embodiment, the via impedance at each substrate layer is constant (e.g., 50 ohms). The interconnect structure can maintain a constant impedance while transitioning from a relatively narrow pitch at the signal source layer to a relatively wide pitch at the terminal layer, which may correspond to the pitch of the package substrate solder balls.

  • Patent number: 6781229
    Abstract: A passive component is realized on-die by fabricating a first conductor from either a layer of interconnect metal comprising copper or aluminum and being between approximately 1.0 micron and approximately 2.0 microns thick, or from a layer of under bump metal comprising either copper or aluminum and being between approximately 2.0 microns to approximately 5.0 microns thick. Following, a first isolation layer is formed over the first conductor. A second conductor having at least one external pad and comprising under bump metal is next fabricated over the first isolation layer. The second conductor can be fabricated substantially directly above the first conductor, for example. Thereafter, a second isolation layer having a hole over the external pad of the second conductor is formed over the second conductor. Subsequently, a bump attach site is fabricated at the hole in the second isolation layer over the external pad of the second conductor.

  • Patent number: 6762494
    Abstract: An electronic package component includes a flip-chip device mounted to a BGA substrate. The BGA substrate includes conductive traces formed on its upper surface and configured in a coplanar waveguide structure. The package includes a dielectric coating applied over the conductive traces and over the upper surface of the substrate. The coating is formed from a material having a dielectric constant that is equal to or approximately equal to the dielectric constant of the BGA substrate material. The dielectric coating reduces the adverse effects caused by phase velocity dispersion of the signal propagated by the coplanar waveguide.

  • Patent number: 6713853
    Abstract: An electronic package, such as a ball grid array (“BGA”) package, includes a high speed signal trace formed at a conductive layer and a corresponding reference plane formed at another conductive layer. The reference plane includes a cutout region formed therein; the cutout region is positioned over the signal solder ball to which the high speed signal trace is coupled. The lateral center point of the cutout region is offset relative to the lateral center point of the signal solder ball. The offset configuration reduces the capacitance between the signal solder ball and the reference plane and improves the high frequency transmission characteristics of the electronic package.

  • Patent number: 6674174
    Abstract: In one embodiment, the invention includes first and second transmission lines fabricated in a redistribution layer over a semiconductor die. The first transmission line has a first distance from a first ground return path formed in a first metal level. The first transmission line has a first impedance corresponding to the first distance. In other words, the impedance of the first transmission line is affected by the distance between the first transmission line and the first ground return path. Similar to the first transmission line, the second transmission line has a second distance from a second ground return path formed in a second metal level. The second transmission line has a second impedance corresponding to the second distance. In other words, the impedance of the second transmission line is affected by the distance between the second transmission line and the second ground return path.

  • Patent number: 6674646
    Abstract: An output of a voltage regulator is a core voltage line that runs adjacent to a die attach area on a packaging substrate. An input of the voltage regulator is typically coupled to a power supply which, in one embodiment, is also an I/O voltage line that runs adjacent to the die attach area. In one embodiment, the core voltage line is shaped as a ring encircling the die attach area on the packaging substrate. In another embodiment, the I/O voltage line is also shaped as a ring encircling the die attach area on the packaging substrate. Further, a semiconductor die having at least one I/O Vdd bond pad and at least one core Vdd bond pad can be mounted in the die attach area. The I/O Vdd bond pad and the core Vdd bond pad can be connected, respectively, to the I/O voltage ring and the core voltage ring.
