Raymond M. Warner, Jr., Professor Emeritus, University of Minnesota, Institute of Technology, Department of
Electrical and Computer Engineering, died Friday, April 16, 2010. Dr. Warner served as professor in the
department from 1970 until his retirement in 1989. He served as chairman of the department's Microelectronics
Research Group from 1970 to 1980.
"Ray was a pioneer in microelectronics, an outstanding colleague and mentor and great friend, " says Professor
Mostafa Kaveh, Electrical and Computer Engineering, University of Minnesota. "He was passionate about global
social and political justice, the environment and associated needs in public transportation, energy efficiency and
sustainability. These were often reflected in his eloquent editorial letters to the local newspapers, which are
"Ray was a quintessential engineer, always balancing his passion for science and technology with practical
concerns about modern society," says Professor James Leger, Electrical and Computer Engineering, University
of Minnesota."His contributions spanned the spectrum, from fundamental microelectronics to public policy."
Dr. Warner received his bachelor’s in physics from Carnegie Institute of Technology (now Carnegie Mellon
University), Pittsburgh, Penn., and his masters (1950) and doctorate in physics (1952) from Case Institute of
Technology (now CaseWestern Reserve University), Cleveland, Ohio.
He was an Army Signal Corps Radio Officer in the European and Pacific Theaters in World War II sharing
responsibility for a VHF radio circuit between the headquarters of Generals George Patton and Omar Bradley.
Dr. Warner was involved in the electronic device and circuit development for nearly forty years, a period he said
that included “a graduate school detour in nuclear physics.” He worked in glass-dielectric capacitors for Corning
Glass Works, Corning , NY; point-contact, mesa, and intrinsic-barrier transistors and junction-field-effect diodes
and tetrodes for Bell Labs, Murray Hill, New Jersey, through most of the 1950s; thyristors and JFETs for Motorola,
Phoenix, Ariz., as Director of Engineering; MOS ICs for Texas Instruments, Dallas, Tex., as Branch Manager;
bipolar ICs for ITT Semiconductors, West Palm Beach, Fla., as U.S. Technical Director; JFETs for Union Carbide
Semiconductors, San Diego, Calif., as U.S. Technical Director; lock-layer and channel-collector transistors and
monolithic series-array solar batteries for the University of Minnesota; and magnetic sensors for 3M.
Dr. Warner was issued 30 patents, and was author of more than 70 journal publications and four technical books,
including principal editor with J.N. Fordemwalt of the Motorola book Integrated Circuits: Design Principles and
Fabrication (New York: McGraw-Hill, 1965); principal author with B.L. Grung of Transistors: Fundamentals for the
Integrated-Circuit Engineering, (New York: Wiley, 1983)(reprinted , Melbourne, Fla.: Krieger); Semiconductor-Device
Electronics (Philadelphia, Penn.: HRW Saunders, 1991); and MOSFET: Theory and Design (New York: Oxford
University Press, 1999). In 1969, he helped conduct a National Science Foundation-sponsored seminar on solid
state electronics at Pilani, India.
Dr. Warner was elected Fellow (1977) and Life Fellow (1992) by Institute of Electrical and Electronics Engineers (IEEE).
In 2001, he received the IEEE Electron Devices Society (EDA) Paul Rappaport Award honoring the best paper
appearing in an EDS publication in the preceding calendar year for "High Performance Bottom Electrode Organic
Thin-Film Transistors", with Ioannis Kymissis, Christos D. Dimitrakopoulos, Sampath Purusothaman, which
appeared in the June 2001 issue of T-ED and for "Microelectronics: Its Unusual Origin and Personality", which
appeared in the November 2001 issue of T-ED.
In the latter part of his career, he worked with mono-crystalline 3-D ICs. This effort led to the creation of SemiCube, Inc.,
Eden Prairie, Minn., in 1999. He also consulted with 16 industrial firms, seven law firms, the National Science
Foundation, and the United Nations.
Dr. Warner was a founding member of Minnesotans for an Energy-Efficient Economy (ME-3) and a cofounder of Citizen
for Personal Rapid Transit (CPRT).
