Reliable peripheral anchor-assisted transfer printing of ultrathin SiO2 for a transparent and flexible IGZO-based inverter

Approaches for processing a brittle SiO2 layer in a stable manner allow its feasible use as a transparent flexible electronic device substrate. Introduction of a sacrificial GeOx layer and SU-8 anchors provides both thermally and mechanically secure fabrication as well as printable formats to allow the “stick-and-play” system on a desired surface.162
