In this article, the mechanics of film-on-foil transistors on steel and plastic foils have been discussed in the context of thin-film transistors, where the transistors function well after the foils are rolled to small radii of curvature.Abstract:
The mechanics of film-on-foil devices is presented in the context of thin-film transistors on steel and plastic foils Provided the substrates are thin, such transistors function well after the foils are rolled to small radii of curvature When a substrate with a lower elastic modulus is used, smaller radii of curvature can be achieved Furthermore, when the transistors are placed in the neutral surface by sandwiching between a substrate and an encapsulation layer, even smaller radii of curvature can be attained Transistor failure clearly shows when externally forced and thermally induced strains add to, or subtract from, each otherread more
