Abstract: The heat resistance of an organic semiconductor device including a step of forming an aluminum oxide film over and in contact with an organic semiconductor layer is improved. A heating step is performed after a layer containing an organometallic compound for a mask for an organic semiconductor layer, which is represented by General Formula (G1) below, is provided over the organic semiconductor layer. In General Formula (G1), Ar represents a substituted or unsubstituted aryl group having 6 to 30 carbon atoms or a substituted or unsubstituted heteroaryl group having 1 to 30 carbon atoms, X represents oxygen or sulfur, M represents a metal, n represents an integer greater than or equal to 1 and less than or equal to 5, and n is the same as the valence of the metal M. Note that when n is greater than or equal to 2, a plurality of Ars may be the same or different and Xs may be the same or different. When Ar represents the substituted or unsubstituted heteroaryl group having 1 to 30 carbon atoms, a heteroatom of the heteroaryl group may be coordinated to the metal M.

The processing apparatus includes a fixing mechanism that fixes part of the stack, a plurality of adsorption jigs that fix an outer peripheral edge of one of the substrates of the stack, and a wedge-shaped jig that is inserted into a corner of the stack. The plurality of adsorption jigs include a mechanism that allows the adsorption jigs to move separately in a vertical direction and a horizontal direction. The processing apparatus further includes a sensor sensing a position of the gap between the end portion in the stack. A tip of the wedge-shaped jig moves along a chamfer formed on an end surface of the stack. The wedge-shaped jig is inserted into the gap between the end portions in the stack.
