Ardasheir Rahman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20190181055
    Abstract: Techniques facilitating three-dimensional monolithic vertical field effect transistor logic gates are provided. A logic device can comprise a first vertical transport field effect transistor formed over and adjacent a substrate and a first bonding film deposited over the first vertical transport field effect transistor. The logic device can also comprise a second vertical transport field effect transistor comprising a second bonding film and stacked on the first vertical transport field effect transistor. The second bonding film can affix the second vertical transport field effect transistor to the first vertical transport field effect transistor. In addition, the logic device can comprise one or more monolithic inter-layer vias that extend from first respective portions of the second vertical transport field effect transistor to second respective portions of the first vertical transport field effect transistor and through the first bonding film and the second bonding film.

  • Publication number: 20190181054
    Abstract: Techniques facilitating three-dimensional stacked vertical transport field effect transistor logic gates with buried power bus are provided. A logic device can comprise a plate and a first vertical transport field effect transistor formed over and adjacent the plate. The logic device can also comprise a second vertical transport field effect transistor stacked on the first vertical transport field effect transistor. The plate can be a power layer and can be continuous within regions of the device that utilize a common voltage. The plate can be contacted from a surface of the device at intervals corresponding to the regions of common voltage. The plate can be electrically connected to ground. Alternatively, the plate can be electrically connected to a power supply.
