  • Patent number: 11649160
    Abstract: Embodiments described herein include systems and techniques for converting (i.e., transducing) a quantum-level (e.g., single photon) signal between the three wave forms (i.e., optical, acoustic, and microwave). A suspended crystalline structure is used at the nanometer scale to accomplish the desired behavior of the system as described in detail herein. Transducers that use a common acoustic intermediary transform optical signals to acoustic signals and vice versa as well as microwave signals to acoustic signals and vice versa. Other embodiments described herein include systems and techniques for storing a qubit in phonon memory having an extended coherence time. A suspended crystalline structure with specific geometric design is used at the nanometer scale to accomplish the desired behavior of the system.

  • Patent number: 11502191
    Abstract: Disclosed herein are IC structures that implement field plates for III-N transistors in a form of electrically conductive structures provided in a III-N semiconductor material below the polarization layer (i.e., at the “backside” of an IC structure). In some embodiments, such a field plate may be implemented as a through-silicon via (TSV) extending from the back/bottom face of the substrate towards the III-N semiconductor material. Implementing field plates at the backside may provide a viable approach to changing the distribution of electric field at a transistor drain and increasing the breakdown voltage of an III-N transistor without incurring the large parasitic capacitances associated with the use of metal field plates provided above the polarization material. In addition, backside field plates may serve as a back barrier for advantageously reducing drain-induced barrier lowering.
