“Towards Heterogeneous Integration of Functional Materials on Flexible and Non-Standard Substrates to Create Microsystems”
Abstract: This presentation traces the development work that we have undertaken over a number of years to integrate multifunctional elements onto flexible substrates. The investigations have pursued many interesting avenues (and some dead-ends), but the overall direction has been towards achieving multifunctional microsystems or modules on flexible substrates, including composite boards (e.g. FR4).
The presentation briefly covers the early and successful work on embedding passives into multilayer printed circuit boards. Passives such as resistors, inductors and capacitors were followed by the integration of simple sensors such as strain and temperature sensors. However, the challenge of integrating high value capacitors required us to address the difficult and innate problem of the temperature incompatibilities: i.e. the limited temperature stability range of the composite or flexible substrate versus the high temperatures required to achieve long range order in ferroelectric oxides to achieve the required high dielectric constants. While other researchers have worked to reduce the oxide processing temperatures to make them compatible with high temperature polymers, we chose instead to process on flexible metal foil substrates, and subsequently integrate with the substrate (e.g. FR4). Success was achieved for PLZT-based thin film capacitors on Ni foil substrates, subsequently BaTiO3-based capacitors on Cu foil, and then PZT ferroelectrics (and piezoelectrics) on similar Cu foil.
In the second part of the presentation I present some of our adventures in adding additional functionality on metal substrates, including thermoelectric, and energy harvesting devices, as well as the effort to increase the thickness dimension to the range of thick film technology. This section of the presentation includes the investigation of lead-free materials on flexible metal foils for ferroelectric devices and high value capacitors.
In the final part of the presentation I present some of the science of processing on metal foil substrates which have a large thermal expansion mismatch with the film. The large biaxial stresses which result can lead to a substantial change in film properties. These biaxial stress effects are discussed in terms of both the imposed limitations, and the opportunities thereby to stress-engineer properties.
Bio: Angus Kingon has been Professor of Engineering, and University Professor of Entrepreneurship and Organizational Studies at Brown University since 2008. He is also the co-Director in the graduate Masters-level Program on Innovation Management and Entrepreneurship (PRIME) at Brown University. He plays a dual role at Brown University as an active researcher in both the physical sciences and social sciences/management.
Angus Kingon completed his undergraduate degrees at the University of the Witwatersrand in South Africa, and his MS and PhD degrees (in Physical Chemistry) at the University of South Africa.
Previously, Professor Kingon was at the North Carolina State University as Professor of Materials Science and Engineering in the College of Engineering, and Professor in the Department of Management, Innovation and Entrepreneurship. Prior to his appointment at NCSU in 1987, he was Program Manager and Specialist Scientist at the National Institute for Materials Research, Pretoria, South Africa.
Dr. Kingon was trained as a physical chemist, his Ph.D. thesis topic was on piezoelectric ceramics, but subsequently expanded his research interests to the processing, characterization and application of a wide range of electronic ceramics and thin films. Some of his research has been commercialized. For example, his work on embedded electronic components was commercialized in conjunction with Motorola. This facilitated miniaturization and cost reduction in cellular phones and mobile devices.
Professor Kingon’s current scientific research covers topics including flexible electronics, piezoelectric actuators and sensors, energy harvesting devices, novel thermoelectric structures, new photovoltaic materials (and their fundamental transport properties), and novel X-ray scintillation detectors.
He has published about 340 papers in refereed journals, edited 7 books, written 8 book chapters, and has 15 issued patents. (Web of Science citations over 9,000, h-index is 46; Google Scholar citations over 15,700, h-index of 62 and an i10-index of 211).
Some of his research has been commercialized, for example for use in mobile phones, and mobile controllers, and in DRAMs for computer memory.
Professor Kingon also studies the commercialization of science. He has led a major NSF project on the commercialization of emerging science and technology, researching new methods to create value from university research centers and institutes, and connecting university research to industry to create breakthrough products and services.
Professor Kingon has been the recipient of a number of awards, and has presented over 150 invited and plenary talks over the past 10 years. He was the co-winner of the Price Foundation Award as Innovative Entrepreneurship Educator for 2006. He is a Fellow of the Center for Innovation Management Studies, and a Fellow of the American Ceramic Society.
