Assoc Prof Ang Diing Shenp
Associate Professor, School of Electrical & Electronic Engineering
Dr. Ang obtained both his B. Eng. (hons) and Ph.D. degrees in electrical engineering from the National University of Singapore. He joined the School of Electrical and Electronic Engineering, Nanyang Technological University in July 2002 as an assistant professor and was promoted to associate professor in April 2008. Dr. Ang’s research interests lie mainly in novel semiconductor devices for advanced memory technologies and neuromorphic (non von Neumann) computing and CMOS reliability physics (NBTI, HCI, and TDDB). Together with his Ph.D. student Ms. Ong Yi Ching, their work on the application of scanning probe techniques to study electronic trap generation in high-k gate dielectrics won them the Bronze prize in the 3rd TSMC Outstanding Student Research Award (under the category of Physics, Chemistry of Material for Nano-Scale Devices). In 2017, his joint work with Mr. Tomohito Kawashima from Toshiba won the first prize of the Best Posters Competition of the China Semiconductor Technology International Conference. Dr. Ang was invited to serve on the technical program committees of the IEEE International Reliability Physics Symposium (2004-2006, 2013), International IEEE International Integrated Reliability Workshop (2009-2013) and IEEE International Symposium on the Physical and Failure Analysis of Integrated Circuits (2004-2015). He also served as a member of the editorial board of the Open Electrical and Electronic Engineering Journal from 2007-2016 and as a guest editor for a topical volume on neuromorphic engineering for Frontiers in Neuroscience.

US 2018/0166495 A1: Sensor Element, Image Sensor, Methods Of Forming And Operating The Same (2019)
Abstract: A sensor element for sensing optical light may be provided. The sensor element may include a first electrode for electrically coupling to a first supply voltage, a second electrode for electrically coupling to a second supply voltage, and an oxide dielectric element between the first electrode and the second electrode. The oxide dielectric element may be configured to form a conductive filament upon a potential difference between the first supply voltage and the second supply voltage exceeding a threshold level, thereby decreasing a resistance of the oxide dielectric element. The sensor element may also include a detector. The first electrode may be configured to allow the optical light to pass through the first electrode to the oxide dielectric element. The detector may be configured to detect an increase in the resistance of the oxide dielectric element upon the oxide dielectric element receiving the optical light.
