Wenbin Chen obtained the B.E. (1H) from Guilin University of Electronic Technology, China (GUET) in 2006. He subsequently enrolled in the M.Eng.Sc. (Microelectronics) programme at UCC, graduating in 2007. From January 2008 to December 2010, Wenbin undertook a Ph.D. in Microelectronic Engineering at UCC, based at the Tyndall National Institute with co-supervisors Dr. Kevin McCarthy of the Department of Electrical and Electronic Engineering and Dr. Alan Mathewson of Tyndall. Wenbin was an associate scholar of ICGEE from 2008 to 2010.
The primary funding for Wenbin’s research was provided by a European Union 6th Framework research project “Monolithic Above IC Ultra high value Capacitors for Mobile and Wireless Communication Systems” (CAMELIA) and by the Higher Education Authority PRTLI-4 programme “Networked and EMBEdded Systems” (NEMBES). The overall aim of CAMELIA was the development of novel high-k dielectrics for the fabrication of high-density capacitors for highly-integrated System-on-Chip ICs while Wenbin’s specific research focus was on the electrical characterization of these novel high-k dielectrics which were fabricated using a material system known as PMNT (Pb(Mg,Nb)TiO3). During his research, Wenbin developed test structures for the electrical characterization of thin-film dielectric layers and applied a wide variety of characterization techniques to the fabricated samples as outlined in his Ph.D. abstract. In collaboration with the CAMELIA research team at Tyndall National Institute led by Dr. Richard Winfield and Dr. Shane O’Brien he demonstrated that it was possible to fabricate PMNT layers with an exceptionally high dielectric constant of over 1000 under certain processing conditions.
Wenbin published extensively during his Ph.D. research with 3 international journal papers and 7 conference publications resulting directly from the work as listed in his Ph.D. abstract. One of the international publications was at the European Materials Research Society (E-MRS) Spring meeting in 2009 at which Wenbin achieved a prestigious “Young Scientist Award”. Wenbin also authored an article in the first edition of a new UCC journal “The Boolean” which showcases the work of research students at UCC. In 2010 Wenbin was honoured with a “Chinese Government Award For Outstanding Self-Financed Students Abroad” – this award is given by the Chinese Government to a small number of Chinese students who have funded their own Ph.D. training abroad and who have reached an exceptional standard in their research.
While at UCC Wenbin was committed to helping and supporting his fellow students and served as chairman of the Chinese Students and Scholars Association, Ireland (CSSA-Ireland) for a number of years. Following graduation in 2010, Wenbin undertook a short research contract at the Tyndall National Institute before returning to China in mid-2011 to continue his academic career.
