Abstract
We use sALD to deposit IGZO and Al2O3 layers in top-gated self-aligned TFTs, achieving a low-temperature process flow (d200oC). We attain mobility of 8 cm2/Vs and switch-on voltage of -0.1 V for transistors with channel lengths down to 1 μm, enabling a 200 ppi QVGA display on transparent PEN foil.
