제목 Effect of softbake temperature on photochemical-annealed IGZO thin film transistors
초록 Flexible electronic components are essential for the development of mechanically flexible functional system, which would allow new applications in electronics, biotechnology, energy and sensing.
Solution-processed oxide semiconductors could meet the requirement of high-performance flexible platform while also achieving a continuous drive for cost reduction.
Photochemical activation route for solution-processed IGZO thin film attracted much attention due to its capability of device fabrication at low temperature. In photochemical activation using deep ultraviolet (DUV) rays, solvents and organic species within metal precursors should be effectively removed for dense metal-oxide-metal network formation, consequently leading to high performance operation of transistors. Unlike a thermal annealing process, however, adequate amount of oxygen-containing solvent is also necessary prior to DUV photoanneal for relevant photochemistry. So, we varied a softbake temperature to optimize the preconditions for DUV-annealed IGZO thin film transistors.  It was found that the performances of IGZO TFTs strongly depend on the softbake temperature. Details of experiment procedures and results will be discussed at the meeting.
