Professor Fan-Yi Ouyang received her B.Sc and M.S. degree in Engineering and System Science from National Tsing Hua University at Hsinchu, Taiwan and Ph.D. in Material Science and Engineering, from University of California, Los Angeles in USA. Her Ph. D research focused on electromigration and thermomigration in eutectic SnPb and Pb-free flip chip solder joints. She then spent around 3 years at Intel Corporation, Portland technology Development Center as Quality and Reliability Engineer to evaluate first level interconnect reliability of various Si-Assembly process on 32 nm technology and develop first level interconnect process on 22 nm technology. She then joined Department of Engineering and System Science at National Tsing Hua University at Hsinchu in August 2010 and currently an Professor and Vice Chairman. She is also Associate Director in Center for Nanotechnology, Materials Science, and Microsystems at National Tsing Hua University in Taiwan She was received TMS EMPMD Young Leader Professional Development Award in 2014, Excellent Young Scientist Award of The Materials Research Society-Taiwan in 2020, and Excellent Young Professional Award of Taiwan Association for Coating and Thin Film Technology in 2020. Her current research interests include mass transport (diffusion) and interfacial reaction in electronic materials, thin film deposition and characterization, and high-temperature oxidation behavior of nuclear materials.

We demonstrate a systematic study optimizing the properties of CoCrFeNi medium entropy alloy (MEA) thin films by tuning the deposition parameters of the pulsed direct current (DC) magnetron sputtering process. The chemical composition and microstructure of thin films were studied with energy dispersive X-ray spectroscopy (EDS), an X-ray diffractometer (XRD) and a transmission electron microscope (TEM). Abundant nanotwins and the dual face-centered cubic−hexagonal close-packed (FCC-HCP) phases were formed in some specimens. The Taguchi experimental method and analysis of variance (ANOVA) were applied to find the optimized parameters. The control factors are five deposition parameters: substrate bias, substrate temperature, working pressure, rotation speed and pulsed frequency. According to the signal-to-noise ratio results, the optimized parameters for low electrical resistivity (98.2 ± 0.8 μΩ·cm), low surface roughness (0.5 ± 0.1 nm) and high hardness (9.3 ± 0.2 GPa) were achieved and verified with confirmed experiments. |
