  This talk is aiming on presenting a novel bio-detecting scheme using IGZO TFTs (thin-film transistors). Since 2004, we conducted a very pioneer work in metal oxide based TFTs in Taiwan. The IGZO TFT with a hybrid dielectric and a carrier confined channel structure we proposed possess world?record?of subthreshold swing. In this talk, I will briefly introduce the electrical behaviors of our IGZO TFTs, and then focus on TFTs for biosensing. I will demonstrate the IGZO TFT with dual gate electrodes that detects electric charges of the target biomaterial. The TFT also functions as a transducer for signal readout. An IGZO TFT-based biosensor integrated with a microfluidic channel can be further used to monitor biochemical reactions between proteins and small molecules. Using Biotin-Streptavidin reaction as an example, the specific diffusion time of biotin, streptavidin, or streptavidin-biotin complex across the fluidic channel are benchmarked. By intentionally delaying the application of one specie to another, we can study properties of biochemical reactions, such as excess and exhaust conditions of the reactants, and the formation of the products while diffusing in the channel. The proposed TFT sensor provides an excellent platform in understanding the biochemical functions for the advance of biological science.



  JianJang Huang received the B.S. degree in Electrical Engineering (EE) and the M.S. degree in Graduate Institute of Photonics and Optoelectronics (GIPO) from Taiwan University (NTU), in 1994 and 1996, respectively, and the Ph.D. degree in Electrical Engineering from the University of Illinois, Urbana-Champaign, in 2002. Prof. Huang is a member of the Phi Tau Phi Scholastic Honor Society. He received“Wu Da-Yu”award in 2008, the most prestigious one for young researchers in Taiwan sponsored by National Science Council. And in the same year, he received the award for the most excellent young electrical engineer from the Chinese Institute of Electrical Engineering. He is the Chairman of GIPO NTU and the director of Innovative Photonics Advanced Research Center, NTU. He was the chair of SPIE (San Diego, CA, USA), Optics & Photonics, International Conference on Solid State Lighting from 2011~2015, and the executive secretary of Taiwan Photonic Society from 2013 to 2016. He has been involved in several industrial and venture positions, including the board director of Unity Opto, Inc (2019-now), Global Communication Semiconductor, Inc. in CA, USA (2011~2019), Tacbright Optronics Corp. in Taiwan (2013~2016) and TMP co. in Taiwan (2012~2013). In academia, he currently serves as the Editor of IEEE, Transactions on Electron Devices, the Associate Editor of IEEE, Transactions on Nanotechnology, the guest editor of Sensors, and the IEEE EDS committee member of Optoelectronics. He is a fellow of SPIE and OSA.
