  • Patent number: 9000564
    Abstract: Use of a replacement metal gate (RMG) process provides an opportunity to create precision polysilicon resistors alongside metal gate transistors. During formation of a sacrificial polysilicon gate, the precision polysilicon resistor can also be formed from the same polysilicon film. The polysilicon resistor can be slightly recessed so that a protective insulating layer can cover the resistor during subsequent replacement of the sacrificial gate with a metal gate. The final structure of the precision polysilicon resistor fabricated using such a process is more compact and less complex than existing structures that provide metal resistors for integrated circuits having metal gate transistors. Furthermore, the precision polysilicon resistor can be freely tuned to have a desired sheet resistance by either implanting the polysilicon film with dopants, adjusting the polysilicon film thickness, or both.

    Abstract: A contiguous layer of graphene is formed on exposed sidewall surfaces and a topmost surface of a copper-containing structure that is present on a surface of a substrate. The presence of the contiguous layer of graphene on the copper-containing structure reduces copper oxidation and surface diffusion of copper ions and thus improves the electromigration resistance of the structure. These benefits can be obtained using graphene without increasing the resistance of copper-containing structure.

  • Publication number: 20150002211
    Abstract: A mechanism is provided for extending useable lifetimes of semiconductor devices that are subject to trapped charge carriers in a gate dielectric. Embodiments of the present invention provide heat to the gate dielectric region from one or more sources, where the heat sources are included in a package along with the semiconductor device. It has been determined that heat, when applied during a period when the channel region of a transistor is in accumulation mode or is not providing a current across the channel, can at least partially recover the device from trapped charge carrier effects. Embodiments of the present invention supply heat to the affected gate dielectric region using mechanisms available where the semiconductor device is used (e.g., in the field).
