Abstract: A packaged IC device in which a die is sandwiched between first and second substrates such that (i) peripheral electrical contact pads of the die are wire bonded to the first substrate, e.g., for routing functional input/output signals, and (ii) core-area electrical contact pads of the die are connected to the second substrate in a flip-chip arrangement, e.g., for routing one or more power supply voltages to the core area of the die. The second substrate has a shape and position that (i) expose the peripheral electrical contact pads of the die for unencumbered machine-implemented wire bonding during the assembly process, and (ii) enable direct electrical connections between the first and second substrates outside the footprint of the die, e.g., by way of the corresponding solder bumps attached between the two substrates.

Abstract: A semiconductor device has an on-die decoupling capacitor that is shared between alternative high-speed interfaces. A capacitance pad is connected to the decoupling capacitor and internal connection pads are connected respectively to the alternative interfaces. Internal connection bond wires connect the decoupling capacitor to the selected interface through the capacitance pad and the internal connection pads in the same process as connecting the die to external electrical contacts of the device.

Abstract: A surface-mounted integrated circuit package containing a semiconductor die has at least two conductive plates on its lower surface for contacting power and ground areas of a printed circuit board (PCB). The conductive plates are electrically connected to metal studs encapsulated within the package and which link the plates to the power and ground grids of the semiconductor die. Power and ground can thus be provided to the package with conductive patterns on the PCB that match with the plates. The resistance of the plates is low and hence the IR drop across the die is low. By supplying power directly to the package via the plates, the peripheral package pins that would otherwise have been allocated for power (and ground) are now freed up for signal assignment.

Abstract: A semiconductor device includes a semiconductor die having opposing first and second main surfaces, contact pads and a metal ring accessible from the first main surface, and signal leads surrounding and spaced from the die. Each of the signal leads has a first end near the die, a second end remote from the die, and a body extending between the first and second ends. A dummy lead frame is disposed between the signal leads first ends and the die, and connected to a fixed potential. First bond wires are coupled to respective ones of the signal leads and the contact pads. Second, shield bond wires, located adjacent to respective ones of the bond wires, are coupled to the dummy lead frame and the metal ring.

Abstract: A method of physical design of an IC using an EDA tool includes identifying elements of the IC design that have excess positive timing slack. The excess timing slack elements are placed in a separate partition and then parameters of the characteristics of the excess timing slack elements are modified to reduce their excess timing slack, such as reducing the voltage supplied to the separate partition, thereby lowering power consumption of the IC design.
