Center for Dielectric Studies (CDS)Pennsylvania State University (lead institution) and University of Missouri at RollaA National Science Foundation Industry/University Cooperative Research Center since 1983An improved understanding of dielectric materials will lead to the development of advanced devices for electronic technology Center Mission and RationaleResearch projects at the Center for Dielectric Studies (CDS) aim to improve the basic understanding of the synthesis, processing, and properties of dielectric materials and the electrode metallizations for electronic devices. These devices include: capacitors, microwave components, hybrid microcircuits, thermistors, packages, multichip modules, and thin-film dielectrics. CDS member companies are a mix of material suppliers, device manufacturers, and final users of electronic devices. Having a vertically integrated set of sponsors helps CDS to maintain focus on problems relevant to industry. The overall CDS research program is almost equally funded by membership fees, State and Federal grants, and industry enhancement projects. Research ProgramThe Center's research thrust areas are:
FacilitiesCDS is housed in the Pennsylvania State University's 70,000 square-foot Materials Research Laboratory, which is designed for the needs of interdisciplinary materials research. The laboratory maintains central facilities common to various types of research and is capable of conducting scanning electron microscopy, environmental scanning electron microscopy, transmission electron microscopy, state-of-the-art x-ray diffraction, thermal analysis, and wet chemical analysis. University of Missouri-Rolla has complementary facilities Processing and Synthesis For processing research, CDS has a computer-controlled furnace room with controlled-atmosphere firing capabilities and a custom-designed, fast-fire furnace. CDS has made a rate-controlled sintering system for studying densification mechanisms in multilayer ceramics. A new automated furnace system for smart control of the binder burnout process is being constructed. Measurements Specialized microwave and RF spectrum analyzers available to CDS can measure up to 26 GHz, while a low frequency FFT dielectric spectrometer is capable of measuring to 1.0 milliHz. Multi-sample dielectric reliability tests are set up for computer-automated data collection. Special Center ActivitiesAt CDS, graduate students and postdoctoral researchers are active participants in the Center's basic and applied research programs. Three students have assisted in CDS research through the Women, Minority, and Disabled High School and Undergraduate Engineering Research Assistants program. To date, a total of 19 students have obtained Ph.D. degrees through the CDS program and 30 students have earned Master's degrees. Approximately 15 students and 14 faculty members currently participate in the Center's programs. Some students supported by fellowships elect to conduct research in the Center, which provides financial support for these research projects. The Center holds symposia on topics of interest to its members, including such subjects as powder analysis methods, reliability of ceramic devices, improvement of multilayer capacitor reliability, multilayer ceramic reliability, and power electronics. To provide broad technology transfer to its sponsors' technical staffs, CDS faculty are also available to conduct one-day seminars at participating company sites. In addition, CDS strongly encourages its member companies to send an R&D; representative to spend time at the Center's lab and believes that this interaction is the most effective method of technology and knowledge transfer from academe to industry. The Center will provide logistical support for visits ranging from one week to one year.
