  • Patent number: 11296131
    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: 20220085324
    Abstract: To realize a high-performance liquid crystal display device or light-emitting element using a plastic film. A CPU is formed over a first glass substrate and then, separated from the first substrate. A pixel portion having a light-emitting element is formed over a second glass substrate, and then, separated from the second substrate. The both are bonded to each other. Therefore, high integration can be achieved. Further, in this case, the separated layer including the CPU serves also as a sealing layer of the light-emitting element.

  • Patent number: 10957723
    Abstract: To provide a semiconductor device in which a layer to be peeled is attached to a base having a curved surface, and a method of manufacturing the same, and more particularly, a display having a curved surface, and more specifically a light-emitting device having a light emitting element attached to a base with a curved surface. A layer to be peeled, which contains a light emitting element furnished to a substrate using a laminate of a first material layer which is a metallic layer or nitride layer, and a second material layer which is an oxide layer, is transferred onto a film, and then the film and the layer to be peeled are curved, to thereby produce a display having a curved surface.

  • Publication number: 20200294848
    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.
