Up to this point in the evolution of leading edge Silicon CMOS technologies the qualification of the latest nodes has been carried out using the methods and targets dictated by digital/logic applications. For RF applications the digital centric methodology and metrics will no longer be applicable. We will discuss the reliability impact and the qualification activities driven by the need to support reliable operation for RF circuit applications. The CMOS solutions for RF applications include the introduction of SOI that may introduce additional reliability considerations. The path to maintaining the advanced CMOS scaling cadence and new reliability limiting factors will be examined from the reliability perspective. We will also review the reliability requirements for RF reliability devices and applications as we prepare to introduce technologies to serve the 5G infrastructure requirements. A closer look will be given to Hot Carriers. The characterization, models and qualification methodologies will be put in the required perspective for the successful qualification and transfer of leading edge technologies to a manufacturing environment.
Dr. Fernando Guarín is a Distinguished Member of Technical Staff at Global Foundries in East Fishkill New York. He retired from IBM’s SRDC after 27 years as Senior Member of Technical Staff. He earned his BSEE from the “Pontificia Universidad Javeriana”, in Bogotá, Colombia, the M.S.E.E. degree from the University of Arizona, and the Ph.D. in Electrical Engineering from Columbia University, NY He has been actively working in microelectronic reliability for over 35 years. From 1980 until 1988 he worked in the Military and Aerospace Operations division of National Semiconductor Corporation. In 1988 he joined IBM’s microelectronics division where he worked in the reliability physics and modeling of Advanced Bipolar, CMOS and Silicon Germanium BiCMOS technologies. He is currently leading the team qualifying GlobalFoundries RF 5G technology offerings. Dr. Guarín is an IEEE Fellow, Distinguished Lecturer for the IEEE Electron Device Society EDS, where he has served in many capacities including; member of the IEEE’s EDS Board of governors, chair of the EDS Education Committee, Secretary for EDS. He was the EDS President 2018-2019.

IN THIS WORK WE DISCUSS PROXY ARCHITECTURES WHICH INTERCONNECT IOT DOMAINS RUNNING COAP WITH THE REST OF INTERNET INCLUDING MICRO DATA CENTERS AND OTHER DOMAINS BUILDING SCALABLE HIERARCHICAL ARCHITECTURES. WE ASSUME THAT COAP DOMAIN IS TERMINATED BY AN IOT PROXY WITH CACHE, AND DESCRIBE AND EVALUATE THREE DESIGN OPTIONS FOR COMMUNICATION ARCHITECTURE. THE FIRST OPTION IS THE DEFAULT SCENARIO WITH UNICAST COMMUNICATION USING POST/GET MESSAGES, WITH PROXY OPERATING IN FORWARD OR REVERSE MODE, AND REACTIVE OR
PROACTIVE DATA COLLECTION. THE SECOND OPTION IS DATA COLLECTION VIA MULTICAST GET MESSAGES FROM THE PROXY, INCLUDING THE IMPACT OF THE LEISURE PERIOD WHICH ALLOWS DEVICES TO REPLY AFTER A ARBITRARY (RANDOM) DELAY UPON RECEIVING A MULTICAST GET REQUEST. THE FINAL OPTION IS THE USE OF 'OBSERVE' FEATURE WHERE CLIENTS SUBSCRIBE TO SERVER NOTIFICATIONS THAT INFORM THEM OF CHANGED DATA VALUES. TO MAINTAIN THE FRESHNESS OF CACHED RECORDS UNDER RANDOM ARRIVALS OF OBSERVED DATA, WE HAVE IMPLEMENTED THE EVALUATION OF MAX-AGE PARAMETER AT THE PROXY. WE HAVE ALSO IMPLEMENTED CONGESTION CONTROL AT IOT NODES WHICH INTERACTS WITH PROXY'S FRESHNESS ESTIMATION AND ALLOWS THE PROXY TO PERFORM ITS OWN CONGESTION CONTROL. WE PRESENT PERFORMANCE DATA OF THESE OPTIONS, INCLUDING THE PROBABILITY OF SUCCESSFUL DATA TRANSMISSION, ROUND TRIP
DELAY AND ENERGY CONSUMPTION.
