  • Patent number: 10084080
    Abstract: A tunneling transistor is implemented in silicon, using a FinFET device architecture. The tunneling FinFET has a non-planar, vertical, structure that extends out from the surface of a doped drain formed in a silicon substrate. The vertical structure includes a lightly doped fin defined by a subtractive etch process, and a heavily-doped source formed on top of the fin by epitaxial growth. The drain and channel have similar polarity, which is opposite that of the source. A gate abuts the channel region, capacitively controlling current flow through the channel from opposite sides. Source, drain, and gate terminals are all electrically accessible via front side contacts formed after completion of the device. Fabrication of the tunneling FinFET is compatible with conventional CMOS manufacturing processes, including replacement metal gate and self-aligned contact processes. Low-power operation allows the tunneling FinFET to provide a high current density compared with conventional planar devices.

  • Publication number: 20180270314
    Abstract: A batch of CRUD operations can be coupled with the resource discovery operation and directly conducted on the matched resources, without initiating new CRUD requests. New functionality at the Originator and Receiver can differentiate the resources for which criteria matching is applied from the resources included in the discovery/filtering results. Enhanced functionality at the Originator and Receiver can combine discovery with RESTful operations targeting a resource set different than but related the discovered resources. Other enhancements may be used to research discovery rights of resources in a specified relationship to those matching a filter, or to request group formation based on the result.
