    摘要: The sizes of an evaporation mask used for a full-color light-emitting device and an evaporation mask used for a lighting device are different from each other. For this reason, separate evaporation masks are necessary, and in the case of processing a large number of substrates at once, many evaporation masks are prepared in accordance with the number of substrates to be processed, thereby increasing the total footprint of a manufacturing apparatus. One object of the present invention is to solve a problem of such an increase. A full-color display device can be manufactured by using a color filter and white light-emitting elements in combination. By this manner, a manufacturing line for the light-emitting device can have some steps in common with a manufacturing line for the lighting device; consequently, the total footprint of the manufacturing apparatus is reduced.

    摘要: An oxide semiconductor film with excellent crystallinity is formed. At the time when an oxide semiconductor film is formed, as a substrate is heated to a temperature of higher than or equal to a first temperature and lower than a second temperature, a part of the substrate having a typical length of 1 nm to 1 μm is heated to a temperature higher than or equal to the second temperature. Here, the first temperature means a temperature at which crystallization occurs with some stimulation, and the second temperature means a temperature at which crystallization occurs spontaneously without any stimulation. Further, the typical length is defined as the square root of a value obtained in such a manner that the area of the part is divided by the circular constant.
