摘要： Provided is a method for manufacturing a semiconductor device, which prevents waste generation from being caused peeling of films and prevents failure of peeling from being caused by waste due to peeling of films. A first semiconductor substrate is used which has a structure in which a peeling layer is not formed in a section subjected to a first dividing treatment, so that the peeling layer is not exposed at the end surface of a second semiconductor substrate when the second semiconductor substrate is cut out of the first semiconductor substrate. In addition, a supporting material is provided on a layer to be peeled of the second semiconductor substrate before the second semiconductor substrate is subjected to a second dividing treatment.

摘要： A semiconductor device with favorable electrical characteristics is provided. In an oxide semiconductor film, a plurality of electron diffraction patterns are observed in such a manner that a surface over which the oxide semiconductor film is formed is irradiated with an electron beam having a probe diameter whose half-width is 1 nm while the position of the film and the position of the electron beam are relatively moved. The electron diffraction patterns include 50 or more electron diffraction patterns observed in different areas. The sum of the percentage of first electron diffraction patterns and the percentage of second electron diffraction patterns accounts for 100%. The first electron diffraction patterns account for 50% or more. The first electron diffraction pattern includes observation points that are not symmetry or observation points disposed in a circular pattern. The second electron diffraction pattern includes observation points corresponding to the vertices of a hexagon.
