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.

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.

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.

Abstract: One object is to provide a deposition technique for forming an oxide semiconductor film. By forming an oxide semiconductor film using a sputtering target including a sintered body of a metal oxide whose concentration of hydrogen contained is low, for example, lower than 1×1016 atoms/cm3, the oxide semiconductor film contains a small amount of impurities such as a compound containing hydrogen typified by H2O or a hydrogen atom. In addition, this oxide semiconductor film is used as an active layer of a transistor.

Abstract: An objective is to increase the reliability of a light emitting device structured by combining TFTs and organic light emitting elements. A TFT (1201) and an organic light emitting element (1202) are formed on the same substrate (1203) as structuring elements of a light emitting device (1200). A first insulating film (1205) which functions as a blocking layer is formed on the substrate (1203) side of the TFT (1201), and a second insulating film (1206) is formed on the opposite upper layer side as a protective film. In addition, a third insulating film (1207) which functions as a barrier film is formed on the lower layer side of the organic light emitting element (1202). The third insulating film (1207) is formed by an inorganic insulating film such as a silicon nitride film, a silicon oxynitride film, an aluminum nitride film, an aluminum oxide film, or an aluminum oxynitride film. A fourth insulating film (1208) and a partitioning layer (1209) formed on the upper layer side of the organic light emitting element (1202) are formed using similar inorganic insulating films.

Abstract: A high-quality light emitting device is provided which has a long-lasting light emitting element free from the problems of conventional ones because of a structure that allows less degradation, and a method of manufacturing the light emitting device is provided. After a bank is formed, an exposed anode surface is wiped using a PVA (polyvinyl alcohol)-based porous substance or the like to level the surface and remove dusts from the surface. An insulating film is formed between an interlayer insulating film on a TFT and the anode. Alternatively, plasma treatment is performed on the surface of the interlayer insulating film on the TFT for surface modification.
