  • Publication number: 20120205656
    Abstract: A thin-film layered electronic device, or array of devices, is formed over a layer structure comprising a flexible substrate, a buffer layer, and a metal layer. The layer structure is annealed to permanently deform the layer structure beyond its plastic deformation limit. The thin-film electronic device is formed thereover by a process according to which all steps are performed at a temperature below that at which further plastic deformation of the buffer layer occurs. In-process strain and runout are reduced, improving device yield on flexible substrates. The metal layer forms a first layer of the thin-film layered device, or array of devices.

  • Patent number: 7878071
    Abstract: The invention is an indenter tip that is modified to permit both compression testing and tensile testing on samples having dimensions smaller than approximately 1 ?m. The modified indenter tip has both a surface that can be used to apply compressive forces, and tines that can be used to engage a free end of a specimen to be tested in tension. The apparatus used to perform the tests includes elements of a scanning electron microscope that permit visualization of the specimen to be tested and the modified indenter tip, so as to permit appropriate alignment and engagement of the same. The apparatus also includes elements of a microindenter that provide mechanical manipulation of the relative position and orientation of the modified indenter tip and of the specimen to be tested, as well as the necessary controls and instrumentation to perform the test and to collect, record and manipulate data.
