Abstract: There have been cases where transistors formed using oxide semiconductors are inferior in reliability to transistors formed using amorphous silicon. Thus, in the present invention, a semiconductor device including a highly reliable transistor formed using an oxide semiconductor is manufactured. An oxide semiconductor film is deposited by a sputtering method, using a sputtering target including an oxide semiconductor having crystallinity, and in which the direction of the c-axis of a crystal is parallel to a normal vector of the top surface of the oxide semiconductor. The target is formed by mixing raw materials so that its composition ratio can obtain a crystal structure.

Abstract: An object is to provide a highly reliable light emitting device which is thin and is not damaged by external local pressure. Further, another object is to manufacture a light emitting device with a high yield by preventing defects of a shape and characteristics due to external stress in a manufacture process. A light emitting element is sealed between a first structure body in which a fibrous body is impregnated with an organic resin and a second structure body in which a fibrous body is impregnated with an organic resin, whereby a highly reliable light emitting device which is thin and has intensity can be provided. Further, a light emitting device can be manufactured with a high yield by preventing defects of a shape and characteristics in a manufacture process.
