New Application For Indium Gallium Zinc Oxide Thin Film Transistors: A Fully Integrated Active Matrix Electrowetting Microfluidic Platform, Jiyong Noh

Doctoral Dissertations

The characterization and fabrication of active matrix TFTs [Thin Film Transistors] have been studied for applying an addressable microfluidic electrowetting channel device. The a-IGZO [Amorphous Indium Gallium Zinc Oxide] is used for electronic switching device to control the microfluidic device because of its high mobility, transparency, and easy to fabrication. The purpose of this dissertation is to optimize each IGZO TFT process including the optimization of a-IGZO properties to achieve robust device for application. To drive the IGZO TFTs, the channel resistance of IGZO layer and contact resistance between IGZO layer and source/drain (S/D) electrode are discussed in this dissertation. …
