4‐1: Invited Paper: Highly Robust Flexible IGZO TFTs and Integrated Circuits

We investigated amorphous metal‐oxide semiconductor based electronics for flexible and stretchable applications. In particular, we demonstrated a‐IGZO and SWCNT hybrid flexible amplifiers on PI substrate. Also, mesa structured a‐IGZO TFTs showed stable electrical operation under 125 μm bending radius up to 10000 cycles, enabling ultra‐flexible 7‐stage ring oscillator circuit.
