Abstract: The present disclosure relates to a Silicon Controlled Rectifier (SCR) in non-planar technology to provide a robust ESD protection in System on Chip employing non-planar technologies. The disclosed SCR incorporates wire or fin shaped nanostructures extending from p-type tap to cathode, from the cathode to anode, and from the anode to n-type tap to provide parallel trigger paths to prevent problem of current crowding at the base emitter junction that limits efficient turn-on in conventional SCRs. The proposed structure helps in offering lower trigger and holding voltage, and therefore very high failure currents. The disclosed SCR has sub-3V trigger and holding voltage to provide an efficient and robust ESD protection in SOCs. The proposed device also offers three times better ESD robustness per unit area. Further the proposed SCR has no added capacitive loading and is compatible with standard process flow and design rules.

Abstract: The present disclosure relates to aluminum based alloys and a method for producing the aluminium based alloys. The method comprises acts of, casting of the aluminium based alloy in a chilled casting mould. Then, aging the cast aluminium based alloy at a first predetermined temperature for a first predetermined time. The aging results in the formation of a first precipitate. Followed by this, solutionizing the aluminium based alloy at a second predetermined temperature for a second predetermined time such that the major alloying element is dissolved in aluminium matrix without much affecting the first precipitate. Then, aging the aluminium based alloy at a third predetermined temperature for a third predetermined time. The aging results in the formation of a second precipitate.

Abstract: A system using cooperative communication with rateless codes is presented that uses communication transmission aspects of cooperative communication with rateless codes over Rayleigh fading channels and queuing aspects for buffering messages at intermediate relays. The system transmits a subsequent message while a current message is en route to the destination by receiving and buffering the current message in queues at intermediate relays. A relay with a best instantaneous communication link to the source may receive a message first and forward the received message to the destination. Alternatively, if inter-relay communication links are strong, all relays may cooperate simultaneously.
