  • Patent number: 10134894
    Abstract: Circuit module designs that incorporate dual gate field effect transistors are implemented with fully depleted silicon-on-insulator (FD-SOI) technology. Lowering the threshold voltages of the transistors can be accomplished through dynamic secondary gate control in which a back-biasing technique is used to operate the dual gate FD-SOI transistors with enhanced switching performance. Consequently, such transistors can operate at very low core voltage supply levels, down to as low as about 0.4 V, which allows the transistors to respond quickly and to switch at higher speeds. Performance improvements are shown in circuit simulations of an inverter, an amplifier, a level shifter, and a voltage detection circuit module.

  • Patent number: 10083912
    Abstract: A package substrate having an opening and through-substrate interconnect structures is attached to a temporary carrier such as an adhesive film. The active surface of an IC die is placed in contact with the carrier substrate within the opening, to temporarily attach the die to the carrier substrate. Another die is attached to the side of the first die furthest from the carrier substrate. In one embodiment, the dies are attached to each other using an epoxy so that their respective non-active surfaces face each other. Bond wires are connected between interconnects at the active surface of the second die and the substrate. The wires are then encapsulated. After removal of the carrier substrate, a build-up interconnect structure is formed that includes external interconnects of the package substrate, such as solder balls of a ball grid array package.
