Gordon Moore

Gordon Moore

Gordon Moore passed away on March 24th at the age of 94. On behalf of the entire Solid-State Circuits Community, I would like to express our sympathy to the Moore family and close colleagues. Gordon Moore was a co-founder of Fairchild Semiconductor and Intel Corporation, and former chairman of Intel. He was also an active philanthropist and the originator of “Moore’s Law.” Dr. Moore was influential in the creation of the Solid-State Circuits Council (the forerunner of SSCS) and served as the Council’s second president. Many of us remember his plenary talk at the 50th anniversary of the ISSCC in 2003.

In 1965, decades before the personal computer revolution, Moore wrote an article in Electronics Magazine that predicted silicon IC technology would create “home computers … automatic controls for automobiles, and personal portable communications”. He also observed that the cost benefits of monolithic integration were improving at an exponential rate. The number of transistors on a silicon chip had doubled every year since ICs were invented a few years earlier, and Gordon predicted this trend continuing into the future. His insights gave engineers and managers a goal, and it pushed our industry to make his predictions come true.

Gordon Moore predicted a pace of change driven by human ingenuity as well as the rules of physics.

Dr. Moore was surprised by the longevity of his vision, and that his observation became such a large part of his legacy. He commented once in an interview, “It’s amazing how often I run across a reference to Moore’s Law.” “In fact, I googled Moore’s Law and I googled Murphy’s Law. Moore beats Murphy by at least two to one.”

Numerous tributes have been published documenting Dr. Moore’s career in the media and online:

Earl McCune

Earl McCune

It is with great sadness that we announce the sudden and untimely death of Earl McCune, IEEE Fellow (‘18) on May 27, 2020, in Santa Clara, California, USA. He was 63 and is survived by his wife, Barbara. At the time of his passing, Earl was a Professor of Delft University of Technology, the Netherlands, a tireless and long-time IEEE volunteer, as well as CTO and cofounder of Eridan Communications, Inc., California, USA. Earl’s longstanding passion for sustainable and energy-efficient radio frequency communications was an essential part of Eridan’s founding inspiration, and his colleagues are deeply saddened to lose his vision, steady leadership and generous spirit. That vision and commitment will also be missed by the IEEE communities that relied on his expertise in developing standards, guiding a roadmap for future network generations, or his willingness to provide necessary reality checks. Although Earl’s time at Delft was sadly cut short, the staff and students of the Microelectronics Department will always remember him for his boundless enthusiasm, humor and unselfish commitment to education and research in the field of wireless communication. His expertise and devotion to radio electronics—and equally importantly—his ability to bring all kinds of students, scientists and business people together, and inspire them with his ideas and dreams, will be greatly missed in Delft, in California, and by his many friends and collaborators around the world.

James D. Meindl

James D. Meindl

James D. Meindl, our treasured friend, colleague and mentor passed away peacefully on June 7, 2020 at his home in Greensboro, Georgia after a long illness. He was 87 years old. Meindl was a giant in the world of semiconductors, a gentleman, and a leader of the highest magnitude.

Meindl was born in Pittsburgh, Pennsylvania and received his Ph.D., M.S., and B.S. degrees in 1958, 1956, and 1955, respectively, in electrical engineering at Carnegie Institute of Technology (now Carnegie-Mellon University). He was an outstanding leader in four distinct venues for 50-plus years.

From 1959-67, at the U.S. Army Electronics Laboratories (USAEL), Meindl worked with integrated circuits (ICs) – a field then barely six months old – and served consecutively as section leader, branch chief, and founding director of the Integrated Electronics Division consisted of 80 people, with responsibility for all USAEL R&D efforts in microelectronics. Meindl worked with early industry pioneers, who taught him about ICs, and he then began his own research, trying to figure out how to make an IC operate at a power level so low that it could be used inside a helmet as part of a radio receiver.

From 1967-1986, at Stanford University, Meindl served as founding director of the Integrated Circuits Laboratory, director of the Stanford Electronics Laboratories, associate dean for research in the School of Engineering, and founding co-director of the Center for Integrated Systems, which was a model for university and industry cooperative research in microelectronics.

While at Stanford, Meindl developed low-power integrated circuits and sensors for a portable reading aid for the blind, miniature wireless radio telemetry systems for biomedical research, and non-invasive ultrasonic imaging and blood-flow measurement systems that led directly to the medical systems in wide use today.

From 1986-1993, at Rensselaer Polytechnic Institute (RPI), he served as senior vice president for academic affairs and provost.

From 1993-2013, at Georgia Tech, Meindl joined the School of Electrical and Computer Engineering as the Joseph M. Pettit Chair Professor in Microsystems and served as the director of the Microelectronics Research Center (MiRC). He retired in 2013.

At Georgia Tech, Meindl was the MiRC director for 20 years, where he pursued work on different solutions for solving interconnectivity problems that arise from trying to interconnect billions of transistors within a tiny chip. Meindl was also the founding director of the SIA/DOD Interconnect Focus Center, leading a national team of more than 60 faculty members from the Massachusetts Institute of Technology, Stanford, RPI, Cornell University, SUNY-Albany, and Georgia Tech. In 2006, he became founding director of the Nanotechnology Research Center, the largest dual facility cleanroom in the southeastern United States, bringing together physical sciences and engineering and biological and biomedical nanotechnology research capabilities. His record of leadership in microelectronics and nanotechnology is unmatched.

Meindl published over 600 articles and four books, and he was issued 23 patents. From 1966-1971, he served as the founding editor of the IEEE Journal of Solid-State Circuits. He served in a leadership role on the IEEE Solid-State Circuits Council, the predecessor of the IEEE Solid-State Circuits Society, acting as President of the Council in 1972 and 1978. He also chaired the International Solid-State Circuits Conference (the world’s pre-eminent forum for integrated circuits) in 1966 and 1969. Meindl’s 90 Ph.D. graduates from Stanford, RPI, and Georgia Tech have had a profound impact on the semiconductor industry and on academia in many roles, including as corporate CEOs, university presidents, and deans. Among some of those Ph.D. graduates are past and current Stanford University faculty members, Jim Plummer (former dean of engineering), Krishna Saraswat, and Richard Swanson, M.I.T. President and faculty member Rafael Reif, Johns Hopkins former President William Brody and current Georgia Tech ECE faculty members Muhannad Bakir, Jeff Davis and Azad Naeemi. Even after graduation, alumni of his research groups considered Meindl as a trusted mentor they turned to when trying to make career and life decisions. He was also determined to pass on to his students his ability to see industry needs far into the future.

Meindl was a strong proponent of research with real world impact and promoted both an entrepreneurial spirit and sense of social responsibility among his students. He can rightly be said to be among the founding fathers of “Silicon Valley”, and the list of companies created by his students or those mentored by him is extensive. Among some of those companies are Cypress Semiconductor, Etron Technology, Lattice Semiconductor, Maxim Integrated Products, SanDisk, SunPower, Zoran and others.

Throughout his career, Meindl was a sought-after advisor or board member of several companies. Some of those companies include Hewlett Packard, IBM, Intel, SanDisk, US Venture Partners, Xerox, Zoran, and others. His extensive leadership and advisory roles in government and industry organizations include the Semiconductor Industry Association (SIA), Semiconductor Manufacturing Technology (SEMATECH), International Technology Roadmap for Semiconductors (ITRS), Interconnect Focus Center (IFC), NSF’s National Nanotechnology Infrastructure Network (NNIN), and others.

Meindl’s leadership and technical awards are many, but a short list includes the 2016 Sigma Xi Monie Ferst Award, the 2006 IEEE Medal of Honor, 2004 SRC Aristotle Award, 2001 Georgia Tech Class of 1934 Distinguished Professor Award, 2000 IEEE Third Millennium Medal, 1999 SIA University Research Award, 1991 ASEE Benjamin Garver Lamme Medal, and 1990 IEEE Education Medal. He was a member of the National Academy of Engineering, a Life Fellow of IEEE, Fellow of the American Association for the Advancement of Science, Eminent Member of Eta Kappa Nu, and a Life Member of Sigma Xi.

Meindl has made a significant and lasting impact on his students, faculty in several universities and many colleagues in the U.S. and around the world. We have been truly honored to have had Jim Meindl as our colleague, mentor, and friend.

This article is based on an original version written by Jackie Nemeth at the Georgia Institute of Technology with additional contributions from students and colleagues in academia and industry.

The IEEE Solid-State Circuit Society intends to establish a Fund in Professor James D. Meindl’s Memory. Further communication regarding the Fund will be posted in the future.
