  • Publication number: 20230317517
    Abstract: Integrated circuit interconnect structures including an interconnect metallization feature comprising a sidewall reacted with a chalcogen into a low resistance liner. A portion of a backbone material or a metal seed layer may be advantageously converted into a metal chalcogenide, which can lower scattering resistance of an interconnect feature relative to alternative diffusion barrier materials, such a tantalum. Scattering resistance of such metal chalcogenide liner materials may be further reduced by actively cooling an IC, for example to cryogenic temperatures.

  • Publication number: 20230317146
    Abstract: Integrated circuits including static random-access memory (SRAM) bit-cells that are actively cooled to a low temperature (e.g., in the cryogenic range) where transistor drive currents become significantly increased and transistor leakage currents significantly reduced. With the drive current improvement, bit-cell capacitance may be reduced by defining narrower transistor fin structures and/or four transistor (4T) bit-cells may be implemented, for example with two parallel transistor fins and colinear gate electrodes.

  • Publication number: 20230005526
    Abstract: A system can be designed with memory to operate in a low temperature environment. The low temperature memory can be customized for low temperature operation, having a gate stack to adjust a work function of the memory cell transistors to reduce the threshold voltage (Vth) relative to a standard memory device. The reduced temperature can improve the conductivity of other components within the memory, enabling increased memory array sizes, fewer vertical ground channels for stacked devices, and reduced operating power. Based on the differences in the memory, the memory controller can manage access to the memory device with adjusted control parameters based on lower leakage voltage for the memory cells and lower line resistance for the memory array.

    Abstract: A semiconductor structure includes first, second, and third transistor elements each having a first screening region concurrently formed therein. A second screening region is formed in the second and third transistor elements such that there is at least one characteristic of the screening region in the second transistor element that is different than the second screening region in the third transistor element. Different characteristics include doping concentration and depth of implant.

  • Patent number: 9991300
    Abstract: Semiconductor devices and methods of fabricating such devices are provided. The devices include source and drain regions on one conductivity type separated by a channel length and a gate structure. The devices also include a channel region of the one conductivity type formed in the device region between the source and drain regions and a screening region of another conductivity type formed below the channel region and between the source and drain regions. In operation, the channel region forms, in response to a bias voltage at the gate structure, a surface depletion region below the gate structure, a buried depletion region at an interface of the channel region and the screening region, and a buried channel region between the surface depletion region and the buried depletion region, where the buried depletion region is substantially located in channel region.
