  • Patent number: 9337341
    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.

  • Patent number: 9299879
    Abstract: The present invention provides a simplifying method for a peeling process as well as peeling and transcribing to a large-size substrate uniformly. A feature of the present invention is to peel a first adhesive and to cure a second adhesive at the same time in a peeling process, thereby to simplify a manufacturing process. In addition, the present invention is to devise the timing of transcribing a peel-off layer in which up to an electrode of a semiconductor are formed to a predetermined substrate. In particular, a feature is that peeling is performed by using a pressure difference in the case that peeling is performed with a state in which plural semiconductor elements are formed on a large-size substrate.

  • Patent number: 9293513
    Abstract: Failure light emission of an EL element due to failure film formation of an organic EL material in an electrode hole 46 is improved. By forming the organic EL material after embedding an insulator in an electrode hole 46 on a pixel electrode and forming a protective portion 41b, failure film formation in the electrode hole 46 can be prevented. This can prevent concentration of electric current due to a short circuit between a cathode and an anode of the EL element, and can prevent failure light emission of an EL layer.

  • Patent number: 9281403
    Abstract: There is provided a peeling method capable of preventing a damage to a layer to be peeled. Thus, not only a layer to be peeled having a small area but also a layer to be peeled having a large area can be peeled over the entire surface at a high yield. Processing for partially reducing contact property between a first material layer (11) and a second material layer (12) (laser light irradiation, pressure application, or the like) is performed before peeling, and then peeling is conducted by physical means. Therefore, sufficient separation can be easily conducted in an inner portion of the second material layer (12) or an interface thereof.

  • Publication number: 20150255325
    Abstract: A semiconductor device having a semiconductor element (a thin film transistor, a thin film diode, a photoelectric conversion element of silicon PIN junction, or a silicon resistor element) which is light-weight, flexible (bendable), and thin as a whole is provided as well as a method of manufacturing the semiconductor device. In the present invention, the element is not formed on a plastic film. Instead, a flat board such as a substrate is used as a form, the space between the substrate (third substrate (17)) and a layer including the element (peeled layer (13)) is filled with coagulant (typically an adhesive) that serves as a second bonding member (16), and the substrate used as a form (third substrate (17)) is peeled off after the adhesive is coagulated to hold the layer including the element (peeled layer (13)) by the coagulated adhesive (second bonding member (16)) alone. In this way, the present invention achieves thinning of the film and reduction in weight.
