2017 - Ching W. Tang, Stephen R. Forrest, and Mark E. Thompson

Ching W. Tang, Stephen P. Forrest, and Mark E. Thompson

The pioneering achievements of Ching W. Tang, Stephen R. Forrest, and Mark Thompson in developing, advancing, and commercializing light-emitting diodes (OLEDs) have created a multibillion-dollar industry for advanced lighting and display applications. OLED technology features a series of thin light-emitting fields to provide brighter light but with less energy compared to traditional LED bulbs and liquid-crystal displays (LCDs). It was the groundbreaking discoveries of Tang during the late 1970s that thin-film devices could emit light when a forward voltage was applied that demonstrated the potential of OLED technology and spurred a new field focused on developing organic optoelectronic devices. He created the organic heterojunction, implemented the double-layer structure for enhancing the efficiency of electron hole recombination, developed new approaches for efficient electrodes, and discovered important emitter materials. Based on Tang’s accomplishments, the first full-color active matrix OLED displays were commercialized.

Building on Tang’s OLED foundations, Forrest and Thompson took the technology to the next level by recognizing that OLED efficiency was being limited by the spin of excited states. They introduced iridium-based phosphorescent dyes that increased internal OLED efficiency from 25% to near 100% and enabled OLEDs to compete with LCDs. To overcome the belief that OLEDs would never be stable enough for use in commercial electronic devices, Universal Display Corporation (UDC) was founded to tackle OLED performance and stability issues. With UDC, Forrest and Thompson engineered electron and hole balance in the emissive layer using multiple new “guest and host” materials in conjunction with new device design and demonstrated high-efficiency red and green OLEDs with less than 5% degradation over multiple years of continuous use at display brightness. Their work fueled the launch of today’s multibillion-dollar OLED industry that provides the display technologies dominating mobile electronic appliances and large-screen, high-definition televisions.

An American Physical Society Fellow and member of the U.S. National Academy of Engineering, Tang is a Professor at the Hong Kong University of Science and Technology, Kowloon, Hong Kong and a Professor at the University of Rochester, Rochester, NY, USA.

An IEEE Life Fellow and member of the U.S. National Academy of Engineering and the U.S. National Academy of Sciences, Forrest is the Peter A. Franken Distinguished University Professor and Paul G. Goebel Professor of Engineering at the University of Michigan, Ann Arbor, MI, USA.

A U.S. National Academy of Inventors Fellow and recipient of the Alexander von Humboldt Research Award (2015), Thompson holds the Ray R. Irani Chair of Chemistry, Materials Science, and Chemical Engineering at the University of Southern California, Los Angeles, CA, USA.

2016 - Masayoshi Esashi

Masayoshi Esashi

Masayoshi Esashi has been a pioneering force of micro-electro-mechanical systems (MEMS) technology for over 40 years, developing and bringing to market the tiny sensors and actuators that provide advanced functionalities in today’s automobiles, cellular phones, industrial equipment, and medical devices. Esashi’s key contributions to biomedical microsensors began in the 1970s, where his work on an ion-sensitive field-effect transistor (ISFET) led to the development of medical catheters for in-vivo pH and PCO2 monitoring. During the 1980s, Esashi developed many MEMS and integrated circuit (IC) devices including a servo-type accelerometer, networked tactile sensor, multifreedom active catheter, and a monolithically integrated capacitive pressure sensor that was commercialized by Toyoda Machine Works. The microfluidic system developed by Esashi during the 1990s, which featured microchannels, flow sensors, valves, and pumps on a silicon wafer, provided the foundation for the micro total analysis system/lab-on-a-chip technologies of today. To provide the often-lacking tools needed for continued innovation of MEMS-based devices, Esashi used his IC research and development experience to help develop etchers, deposition machines, and special lithography and evaluation tools. His development of an ion-reactive etcher enabled the fabrication of deep trenches in silicon, which was critical to the commercialization of inertial sensors now used in over 1 million automobiles for active safety control. Another hallmark of Esashi’s career has been his belief in “open innovation” collaboration. He established the Micro System Integration Center where companies can work together to advance MEMS technologies. This has resulted in wafer-level-based hetero-integrated devices such as piezoelectric MEMS switches for mobile phones, monolithic tunable filters for cognitive radios, MEMS-on-IC networked tactile sensors for human-friendly robots, and massively arrayed electron beam emitters for maskless high-speed nanolithography.

An IEEE member and recipient of the Medal with Purple Ribbon from the government of Japan, Esashi is a professor with Tohoku University, Sendai, Miyagi, Japan.

2015 - Dimitri Antoniadis

Dimitris Antoniadis

Known for his deep understanding of device physics, Dimitri Antoniadis has made pioneering contributions to the direction of the integrated circuit (IC) microelectronics industry by advancing the capabilities of metal oxide semiconductor field-effect transistors (MOSFETS). MOSFETs are used for amplifying and switching signals, and today’s microprocessors and memory devices contain billions of them. In 1978 while at Stanford University, Dr. Antoniadis developed the SUPREM process simulator, which was the first computer-aided design tool for silicon semiconductor devices and ICs. SUPREM became the preeminent simulator used by practically all IC manufacturers. His work on deep submicron MOS devices during the 1980s was one of the first demonstrations of nano-scale MOSFETs, and his innovations have continued to the foundation of today’s high-performance silicon FETs. At MIT, Dr. Antoniadis’ groundbreaking research in 1985 proved the feasibility of sub-100-nm MOSFETs and provided the first demonstration of source-to-channel electron injection velocities exceeding saturation velocity. Known as “velocity overshoot,” this provides an increase in current drive in short-channel MOSFETs, enabling higher performance previously not thought attainable. His development of the virtual-source model to describe the behavior of very short channel devices has shown the role of high carrier velocity and mobility in obtaining maximum device performance. With the ability to accurately simulate the characteristics of MOSFETs down to 22 nm and beyond, the model has been adopted by the International Technology Roadmap for Semiconductors (ITRS) for predicting the future of MOSFET scaling. As director for twelve years of the Materials, Structures, and Devices Center, Dr. Antoniadis has helped determine the most promising path for future microelectronics by pursuing scaling of MOS to its ultimate limit and interdisciplinary exploration of new-frontier devices.

An IEEE Life Fellow and member of the US National Academy of Engineering, Dr. Antoniadis is currently a professor and the Ray and Maria Stata Chair in Electrical Engineering at the Massachusetts Institute of Technology, Cambridge, MA, USA.

2014 - Franz Laermer and Andrea Urban

Franz Laermer and Andrea Urban

The development of the deep reactive ion etching process by Franz Laermer and Andrea Urban revolutionized the micro-electro-mechanical systems (MEMS) industry by enabling cost-effective production and proliferation of devices such as the tiny sensors found in automobile air bag and anti-skidding systems, as well as in today’s smartphones and laptop computers. Patented in 1994, the process allowed for precise manufacturing of complex structures in high-quality mono- and poly-crystalline silicon compared to existing anisotropic wet etching methods. Considered a major turning point in the commercialization of MEMS technology, the process enabled the design of more sophisticated and compact devices but at lower cost. It helped overcome the cost barrier to widespread use of silicon accelerometers for air bag sensors, and yaw-rate sensors for car stability control, making these important safety features accessible to more than just high-end automobiles. The process also made possible new generations of affordable sensors used in mobile phone applications, hard-disk protection in laptops, and human-gesture recognition in video game controllers. The technology has also impacted MEMS devices in healthcare, such as DNA chips and disposable blood pressure sensors. Dr. Laermer and Ms. Urban were also instrumental in guiding Bosch to license the process to other manufacturers instead of tightly guarding the intellectual property. This helped in the tremendous growth and commercial success of the MEMS industry, with large manufacturers using the process for their own MEMS-based devices and enabling the start-up of many smaller companies to provide contributions to MEMS technology. The pair was honored with the 2007 European Inventor of the Year Award (Industry Category) for their work on and subsequent success of the deep reactive ion etching process.

Dr. Laermer is vice president of corporate sector research and advance engineering – microsystems, with Robert Bosch GmbH, Stuttgart, Germany. Ms. Urban is a senior expert with the Engineering Sensor Process Technology Department, Robert Bosch GmbH, Reutlingen, Germany.

2013 - Burn J. Lin

Burn J. Lin

Known for pushing the envelope in developing advanced lithography methods, Burn J. Lin’s innovations have revolutionized integrated circuit production and enabled the continued miniaturization of electronic devices. Dr. Lin’s vision has consistently provided advancements that have extended the potential of optical lithography. He pioneered immersion lithography and was the driver of its adoption by the semiconductor industry over traditional optical lithography methods. Optical lithography is used to delineate the circuit patterns of an integrated circuit and has enabled feature sizes of electronic devices to scale down. However, when the industry was looking to reduce the imaging wavelength from 197 to 157 nm to achieve the next reduction in device feature size, Dr. Lin saw an expensive dead end with current optical lithography methods and proposed immersion lithography in 2002. With immersion lithography, Dr. Lin demonstrated that replacing air with water in the gap between the lens and wafer surface provides higher resolution potential than with dry optics. His perseverance in convincing the industry to make the change to immersion lithography has extended Moore’s law from 40 nm to potentially as low as 10 nm. That at least 82% of all transistors currently in the world have been made with immersion lithography is a testament to Dr. Lin’s impact. Throughout his 42-year career in lithography, Dr. Lin pioneered deep-UV lithography, multilayer resist systems, simulation of partially coherent images in 3D, resolution and depth of focus scaling equations, Exposure-Defocus window, and k1 reduction using resolution restoration and enhancement. 

An IEEE Life Fellow and member of the U.S. National Academy of Engineering, Dr. Lin’s many honors include the IEEE Cledo Brunetti Award (2009). Dr. Lin is a Vice President of Research and Development and the Distinguished Fellow with the Taiwan Semiconductor Manufacturing Company, Ltd., Hsinchu.

2012 - Mark T. Bohr, Robert S. Chau, and Tahir Ghani

Mark T. Bohr, Robert S. Chau, and Tahir Ghani

Mark T. Bohr, Robert S. Chau, and Tahir Ghani have played key leadership roles at Intel Corp. in developing the three biggest changes in transistor technology over the past decade. Their work has allowed the continued shrinking of transistor technology resulting in smaller, faster, and more energy-efficient microprocessors. The first revolutionary change in transistor technology was the team’s development of silicon germanium strained-silicon transistors, first described by Dr. Ghani in 2003. Applied in Intel’s 90-nm technology node, these transistors were the first material innovations implemented to improve transistor performance without increasing current leakage. This method improves electron and hole mobility in a transistor, providing faster on-off switching and resulting in faster microprocessors. Intel began volume production of the 90-nm transistors in 2003. The team’s second contribution to the continued scaling of chips was the high-k metal gate transistor that permitted scaling to the 45-nm generation. This technology overcame the performance and leakage limits presented by not being able to scale the gate dielectric in previous nodes. Intel replaced traditional silicon dioxide materials with a novel high-k dielectric and special metal gate electrode to achieve record-setting transistor performance with dramatically reduced current leakage. Intel began high-volume production of 45-nm microprocessors in 2007. The team’s third innovation was the tri-gate transistor featured in Intel’s 22-nm processors announced in 2011. Utilizing three sides of tall and narrow silicon fins to provide better gate control of current compared to traditional planar devices, these transistors provide significantly lower operating voltage, lower current leakage, and more “on state” current. This invention allows transistors that are smaller, faster, and use less power than ever before.

An IEEE Fellow, Mr. Bohr is currently an Intel Senior Fellow and director of process architecture and integration at Intel Corp., Hillsboro, Ore., where he has worked since 1978.

An IEEE Fellow, Dr. Chau is currently an Intel Senior Fellow and director of transistor research and nanotechnology at Intel Corp., Hillsboro, Ore., where he has worked since 1989.

An IEEE Fellow, Dr. Ghani is currently an Intel Fellow and director of transistor technology and integration at Intel Corp., Hillsboro, Ore., where he has worked since 1994.

2006 - Hideo Sunami, Mitsumasa Koyanagi, and Kiyoo Itoh

2006_nishizawa.jpg

Hideo Sunami, Mitsumasa Koyanagi and Kiyoo Itoh are responsible for three of the major milestones in the evolution of modern dynamic random access memories (DRAMs). Their development of trench and stacked capacitor cells and folded data line cells resulted in unmatched high signal-to-noise ratio. Today, three decades after their invention, these cells remain the de facto standard for the DRAM industry.

Dr. Sunami was, in 1975, clearly ahead of his time when he invented the trench capacitor cell while the 4Kb DRAM was still the industry standard. This capacitor ultimately drove the development of dry etching, defect control and inspection associated with high-aspect ratio trenches. Today, the trench capacitor cell is used widely in commodity DRAM products and embedded applications. The concept also includes present cylindrical stack capacitor cells. He is currently a professor at the Research Center for Nanodevices and Systems, Hiroshima University in Hiroshima, Japan.

In 1976, Dr. Koyanagi devised the stacked capacity cell, the dominant DRAM cell since the 1-Mb generation came into being. His work has stimulated research and development on a variety of stacked capacitor cell structures,capacitor insulators and capacitor electrode structures, including those using hemispherical grain, high-k material and metal/insulator/metal. His work has also been successfully applied to other memory devices with three-dimensional stacked structures, such as ferroelectric RAM (FRAM). He is currently a professor in the Department of Bioengineering and Robotics, Tohoku University in Sendai, Japan.

In 1974, Dr. Itoh conceived the concept of the folded data-line cell, which uses a pair of balanced data lines to eliminate various noise components. Since that time, this cell has been adopted for nearly all DRAM chips since produced. A Fellow at Hitachi, Ltd. in Tokyo, where he is responsible for all research and development, he has also developed key DRAM devices and circuits such as the triple-well structure, on-chip voltage down-converters and subthreshold-current reduction circuits.

An IEEE Fellow, Dr. Sunami is the recipient of the IEEE Cledo Brunetti Award, the IEEE Electron Devices Society (EDS) Paul Rappaport Award and the Tokyo Governor’s Award - Distinguished Inventor.

An IEEE Fellow, Dr. Koyanagi is the recipient of the IEEE Cledo Brunetti Award, SSDM Award of the International Conference on Solid-State Devices and Materials, Commendation by the Ministry of Education, Culture, Sports, Science and Technology - Person of science and technological merits (Japan),and the Okochi Memorial Technology Prize.

2005 - Jerry M. Woodall

A U.S. National Medal of Technology Laureate and a Professor of Electrical and Computer Engineering at Purdue University in West Lafayette,Indiana, Dr.Jerry M.Woodall changed the way research is conducted in compound semiconductors. His contributions, in turn,have sparked the successful commercialization of a broad range of new opto-electric and high-speed devices.

Earlier in his career, as a staff researcher at the IBM Research Division in Yorktown Heights, New York, Dr.Woodall developed the liquid phase epitaxy (LPE) of the gallium arsenide (GaAs) high-efficiency IR light emitting diodes used in remote control and data-link applications. He also pioneered the use of liquid phase epitaxy of gallium aluminum arsenide (GaAIAs) and the GaAIAs/GaAs heterojunction, which he used to fabricate super-bright red LEDs, high-efficiency solar cells and the heterojunction bipolar transistor used in cellular telephones. He tapped this same technology to create the ?pseudomorphic? high-electron-mobility transistor widely used in devices and circuits, which offers highly uniform thickness, excellent repeatability, low maintenance, high throughput and low cost of ownership, among other advantages.

An IEEE Fellow, he has received the IEEE Jack A. Morton Award and the IEEE Third Millennium Medal, five major IBM Research Division awards and 30 IBM Invention Achievement Awards. He is the founder and first chairman of the Energy Technology Division of the Electrochemical Society and a recipient of its Edward Goodrich Acheson Award.
