Management

Dadi_reduced_2Dr. Dadi Gudmundsson has researched and worked in semiconductor yield management for the past eleven years. His primary focus has been the field of semiconductor inspection capacity planning. In this new field his experience includes algorithm research, software development, and consulting service deployment. Other related experience includes test structure based yield learning systems and defect detection algorithms for scanning electron microscopes.

Dr. Gudmundsson received a Ph.D. in Industrial Engineering and Operations Research from Berkeley in 2005. His research interests are stochastic and simulation models of production systems. His thesis focused on inspection and metrology capacity planning in semiconductor manufacturing. From 1998-2004 he worked as an inspection planning specialist and consultant at KLA-Tencor. Main responsibilities were the development and deployment of inspection capacity planning tools. He has supervised and personally performed numerous inspection planning projects at leading semiconductor fabs worldwide. Dr. Gudmundsson has published extensively on the topics of inspection and metrology planning [list of publications]. He has served as a reviewer for IEEEs ICRA conference and currently reviews for IEEE Transactions on Automation Science and Engineering.

mikezhang_small_02_156x210Dr. Mike Tao Zhang has worked in semiconductor manufacturing for the past nine years. Most recently he was a Senior Manager/Director of Automation & Industrial Engineering at Spansion's Submicron Development Center. In that function he managed a division of two departments (Automation; Automated Material Handling System) and two groups (IE/Decision Support Systems; Fab Logistics). Before his position at Spansion, Dr. Zhang served in several roles over a five year span with Intel. His positions at Intel included Senior Automation Engineer, Flash factory IE manager, systems IE manager, department manager, and staff technologist. During this time he worked in multiple Intel factories in the US and Asia. At both Spansion and Intel, Dr. Zhang and his team received several awards and recognitions for the implementations of automation and productivity systems. He is also the recipient of the IEEE RAS Early Career Award and the IIE Outstanding Young Industrial Engineer Award.

Dr. Zhang received his Ph.D. in Industrial Engineering and Operations Research from Berkeley in 2001. He also has a M.S. in Mechanical and Aerospace Engineering (Automation focus) from North Carolina State University, and a B.S. in Mechatronics. He has served as the Executive Vice President of the US-China Green Energy Council and has a wide involvement in industrial and academic venues through conference committees, as a reviewer, and a journal editor. Dr. Zhang has published extensively on the theory and application of industrial engineering and operations research to semiconductor manufacturing [list of publications].

Technical and affiliated consultants

Professor J. George Shanthikumar

Dr. Shanthikumar is Professor of Industrial Engineering and Operations Research in the college of Engineering at the University of California, Berkeley. His research interests are in production and service systems modeling and analysis, queueing theory, reliability, scheduling, stochastic processes, simulation and supply chain management. He has written or written jointly over 250 technical papers on these topics. He is a coauthor (with John A. Buzacott) of the book Stochastic Models of Manufacturing Systems and a coauthor (with Moshe Shaked) of the book Stochastic Orders and Their Applications.

He is (or was) a member of the editorial boards of the IIE Transactions on Design and Manufacturing, International Journal of Flexible Manufacturing Systems, Journal of Discrete Event Dynamic Systems, Journal of Production and Operations Management, Operations Research, Operations Research Letters, OPSEARCH, Probability in the Engineering and Informational Sciences, and Queueing Systems: Theory and Applications.

For the past ten year Professor Shanthikumar has consulted leading semiconductor equipment manufacturers on the economics of process control in semiconductor manufacturing.

Dr. Wooseung Jang

Dr. Jang is an Associate Professor of Industrial Engineering at the University of Missouri – Columbia. His primary research interests are in the area of stochastic modeling and optimization, with applications to manufacturing systems, service operations, and supply chain management. Dr. Jang received his Ph.D. degree in Industrial Engineering and Operations Research from the University of California at Berkeley, in 1997. There he was actively involved in the Sloan Focus Study and the SRC projects on Yield Management. Dr. Jang worked with many leading semiconductor companies such as AMD, TI and DEC to develop and implement his research work.

Dr. Jang is a member of the Institute for Operations Research and Management Science, the Mathematical Association of America, and the Manufacturing and Service Operations Management Society. His research work has been published in leading journals such as Naval Research Logistics, Operation Research Letters, European Journal of Operational Research, and International Journal of Productions Research [partial list of publications].
