Continuous Liquid Metal Printing for Rapid Metal Oxide TFT Integration

Scheideler, William J. ; Hamlin, Andrew B. ; Ye, Youxiong ; Agnew, Simon ( March 2023 , 2023 7th IEEE Electron Devices Technology & Manufacturing Conference (EDTM))

We present a rapid liquid metal printing process (CLMP) enabling fabrication of high-mobility metal oxide semiconducting channels in less than 3 seconds. We use this process to engineer heterostructure TFTs with channels consisting of 3 nm layers of In2O3 and Ga2O3 with improved subthreshold slope and enhanced on-state performance (uave∼14cm2/Vs) . We report the influence of deposition temperature and speed, investigating crystallinity and grain morphology of this class of 2D oxide semiconductors.
