[Abstract]
Due to the high transparency, low off-current and relatively high mobility, metal-oxide (MO) thin-film transistor (TFT) is hotly pursued for replacing Si-based TFT in future high-resolution displays. However, MO TFTs were still implemented with the conventional device architectures of Si-based TFTs, including back-channel-etched (BCE), etch-stop (ES) and top-gate (TG). Due the different natures between MO and Si, these three kinds of MO TFTs respectively suffer from the channel damages, large footprint and relatively poor reliability. Based on the discovered unique annealing behavior of MO, a novel MO TFT, dubbed elevated-metal metal-oxide (EMMO) TFT was proposed. Incorporated with the annealing-induced source/drain (S/D), EMMO TFT simultaneously provided high performance/reliability while retained a small device footprint for high-resolution displays, which can hardly be achieved in conventional MO TFT architectures.
 
[Biography]
Dr. Lei Lu received the BS and MS in Microelectronics from Soochow University in 2007 and 2010 respectively, and then the PhD in Electronic and Computer Engineering (ECE) from Hong Kong University of Science and Technology (HKUST) in 2014. Dr. Lu was appointed as a Research Associate in the Dept. of ECE of HKUST from 2014, and then joined the HKUST Jockey Club Institute for Advanced Study (IAS) as a Postdoctoral Fellow in 2016. Currently, he is a Research Assistant Professor in the Dept. of ECE and is concurrently appointed as the IAS Junior Fellow.
Dr. Lu is also with the “State Key Laboratory on Advanced Displays and Optoelectronics Technologies (SKL)” and working with Profs. Man Wong, Hoi-Sin Kwok and Ching Tang on various research areas, including the metal-oxide (MO) semiconductor materials, novel thin-film transistors (TFTs), advanced display technologies and Microelectromechanical system (MEMS) transducers. These research outputs have been published in top electronic journals, such as IEEE TED, EDL and APL and drew attention on the world’s top display, transducer and electronic device meetings, such as SID display week 2016/2018, Transducer 2017 and IEEE IEDM 2016.
