Some embodiments also provide high speed interfaces between these machines. Some or all of these interfaces operate in non-blocking, lockless manner in order to ensure that critical near RT RIC operations (e.g., datapath processes) are not delayed due to multiple requests causing one or more components to stall. In addition, each of these RIC components also has an internal architecture that is designed to operate in a non-blocking manner so that no one process of a component can block the operation of another process of the component. All of these low latency features allow the near RT RIC to serve as a high speed IO between the E2 nodes and the xApps. |

Nanowire transistors employing carbon-based layers
Techniques are disclosed for forming nanowire transistors employing carbon-based layers. Carbon is added to the sacrificial layers and/or non-sacrificial layers of a multilayer stack forming one or more nanowires in the transistor channel region. Such carbon-based layers reduce or prevent diffusion and intermixing of the sacrificial and non-sacrificial portions of the multilayer stack. The reduction of diffusion/intermixing can allow for the originally formed layers to effectively maintain their original thicknesses, thereby enabling the formation of relatively more nanowires for a given channel region height because of the more accurate processing scheme. The techniques can be used to benefit group IV semiconductor material nanowire devices (e.g., devices including Si, Ge, and/or SiGe) and can also assist with the selective etch processing used to form the nanowires. The carbon concentration of the sacrificial and/or non-sacrificial layers can be adjusted to facilitate etch process to liberate nanowires in the channel region. |
