ONLY A FEW TABLETOPS REMAIN
Contact bschieman@imaps.org or Register Online

The purpose of this Workshop organized each year by IMAPS is to promote presentation and discussion of leading-edge developments in thermal management components, materials, and systems solutions for removing, spreading, and dissipating heat from microelectronic devices and systems. The Workshop emphasis is for practical, high-performance solutions intended to meet current and evolving requirements in power electronics, military/aerospace, computing, and telecom systems. Single-company product development concepts are acceptable subjects; however, all abstracts will be judged on novel and innovative contributions to the industry knowledge.

This Advanced Technology Workshop and Tabletop Exhibition on Thermal Management has been held since 1992, and is considered to be one of the most successful of the IMAPS ATWs that are held each year.

Managing Thermal & Mechanical Interactions with 2.5D and 3D IC’s

Abstract: Current 2.5D and 3D chip integration technologies, targeting high performance and high density die-to-die interconnect, are reviewed. State of the Art is summarized, and the principal value propositions opportunities , and technology tradeoffs are highlighted. Principal implementation challenges are outlined, with focus on managing the thermal and mechanical interactions. It is concluded that whereas the thermal and mechanical challenges are not unique and specific to 2.5D and/or 3D stacks, use of these integration technologies does exacerbate the interactions. Possible methodologies for addressing and managing the thermal and mechanical challenges are outlined and discussed.

Biography: Riko Radojcic is a Senior Director of Technology at Qualcomm Technologies, and a leader of the 2.5D and 3D Technology Integration team. He has led a number of Design-for-Technology initiatives at Qualcomm; including Design-for-3D, Design-for-Multiphysics, Design-for-Manufacturability & Variability, etc.. Radojcic has more than thirty years of experience in the semiconductor industry, specializing in process-design integration. Before joining Qualcomm, he was a consultant to semiconductor and EDA companies providing engineering and business development services. He was a director of business development and marketing for DFM Solutions at PDF Solutions, and a Business Manager and an Architect with Tality and Cadence, specializing in design technology integration and process characterization and modeling. Radojcic has held a series of managerial and engineering positions with Unisys and Burroughs, in device engineering, failure analyses and reliability engineering areas. He began his career as a process engineer with Ferranti Electronics, UK.

Radojcic has authored and co-authored a number of books and papers, since he received his BSc and PhD degrees from University of Salford, UK.

Thermal and Mechanical Considerations and Challenges for Mobile and Handheld Products - System to Silicon

Abstract: Consumers are drawn towards mobile devices (tablets, phablets, and phones) which provide thinner form factors, richer and bigger displays and better multimedia capabilities. The functionality crammed into mobile devices will only continue to grow as consumers turn to their mobile devices to do more of their complex and rich functionality tasks. Thermal management and control of these passively cooled devices is of prime importance given the chassis design constraints and thermodynamic space limitations. At the same time, end users expect high levels of performance from their hand-held and mobile devices, and the trend from one generation to the next is increased performance while reducing thermodynamic space (thinner devices). The intersection of these two design philosophies meets at the end-user expectations: is the user willing to trade ergonomics (hotter devices) for increased performance, or is the end user willing to sacrifice performance for better ergonomics & battery life? These questions bring unique challenges for the thermo-mechanical community. This talk discusses most of these major challenges for current and next-generation mobile devices from an industry perspective and also various approaches that need to be taken to balance performance with ergonomics in a quantifiable manner.

Biography: Dr. Ponniah Ilavarasan recently joined Intel China Platform Engineering Group (CPEG) focusing on enabling silicon partners to deliver IA as part of their SOC that can be used in Smartphones and Tablets. Before joining CPEG, he managed the Power, Performance, and Thermal team in Intel’s Mobile Communication Group (MCG) in Portland, Oregon. He holds a Ph.D. degree in Electrical Engineering from Michigan State University. His group is responsible for delivering maximum performance in a thermally constrained environment such as Tablet, Phablet, and Smartphone. This includes delivering cost optimized system thermal solutions for maximum sustainable component and system thermal power envelope in a thin form factor devices, and collaborating with power/silicon architects to minimize power for high stress use cases. Ponniah also managed various disciplines such as EMI/ESD, wireless/antenna design, and signal integrity.

Dr. Ashish Gupta holds a Ph.D. degree in Mechanical Engineering from Purdue University and manages the Thermals and Fluids Core Competency Team at Intel Corporation. His group is responsible for the R&D of advanced package thermal and cooling technologies, modeling methodologies and metrologies for Intel’s current and future generations of processors for product segments during the discovery, definition, development and certification stages of technology maturity. The team‘s scope cover the entire gambit of Intel product segments across all market segments ranging from hand held devices in constrained physical/thermal environments to higher power server products.
