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

Some elementary connections between curvature and mismatch strain in compositionally graded thin films
TL;DR: In this paper, the relationship of the overall curvature of the film to the variation of properties and mismatch strain is reviewed, and it is shown that the mismatch strain distribution in the film can be expressed in terms of the dependence of curvature on film thickness.

Elastic Bending of Semiconductor Wafer Revisited and Comments on Stoney's Equation
TL;DR: In this article, the authors re-examine the Stoney's equation and point out that it was derived based on a neutral axis for zero bending moment which does not exist in the pure bending of a steel ruler on which his derivation was based.
