  • Patent number: 8138670
    Abstract: The inventors have anticipated that there is no problem in employing electron gun deposition as a method of forming a metallic layer on an EL layer of an active matrix light-emitting device because the TFT of the active matrix light-emitting device is disposed below the EL layer. However, since the TFT is extremely sensitive to ionized evaporated particles, the secondary electron, the reflecting electron, and so on generated by the electron gun, while little damage is observed on the EL layer, significant damage is found on the TFT when electron gun deposition is employed. The invention provides an active matrix light-emitting device having superior TFT characteristics (ON current, OFF to current, Vth, S-value, and so on), in which an organic compound layer and a metallic layer (cathode or anode) are formed by means of resistive heating having least influence to the TFT.

  • Publication number: 20110089811
    Abstract: The object of the invention is to provide a method for fabricating a semiconductor device having a peeled layer bonded to a base material with curvature. Particularly, the object is to provide a method for fabricating a display with curvature, more specifically, a light emitting device having an OLED bonded to a base material with curvature. An external force is applied to a support originally having curvature and elasticity, and the support is bonded to a peeled layer formed over a substrate. Then, when the substrate is peeled, the support returns into the original shape by the restoring force, and the peeled layer as well is curved along the shape of the support. Finally, a transfer object originally having curvature is bonded to the peeled layer, and then a device with a desired curvature is completed.
