On-Chip Embedded Cooling of Power and Logic Components

Dr. Avram Bar Cohen, Prinipal Engineering Fellow at Raytheon Corp. - Space Air Borne Systems

Friday, May 12, 2017 1:00 PM - 2:00 PM

Thermal packaging technology has been a key enabler in the development of today’s microelectronic systems, including smart phones, tablet computers, back-room data-crunching supercomputers, and the navigation systems that have come to define our lives in the 21st Century. Much of the benefit that we derive from miniaturization, higher performance, lower cost and greater reliability of these quintessential 21st Century “widgets,” can be traced to improvements in thermal technology, thermal modeling, and the integration of thermal management principles and techniques into electronic product development. A review of thermal packaging over the first 70 years of the Information Age will reveal a relentless “inward migration” of cooling technology from room ventilation and air-conditioning, to cabinet cooling, to component cooling with heat sinks and cold plates, and to today’s efforts to address on-chip hot spots and near-junction thermal transport. Attention will then be devoted to current thermal management requirements, driven by nano-electronics, which confront packaging engineers with the simultaneous “triple threat” of high-power, “hotspots,” and 3D integration in applications as diverse as high performance computing, power electronics, and RF systems. The lecture will close with a review of 3rd-generation thermal management technologies relying on intra- and interchip microfluidic cooling, use of diamond substrates, and on-chip thermoelectric coolers to implement the emerging “embedded cooling” paradigm.
