Patent ID: 8609442

Claim:
A vapor deposition method for forming a coating film having a predetermined pattern on a substrate, the method comprising a vapor deposition step of forming the coating film by causing vapor deposition particles to adhere onto the substrate, wherein the vapor deposition step is a step in which with the use of a vapor deposition unit including a vapor deposition source having a plurality of vapor deposition source openings that discharge the vapor deposition particles, a vapor deposition mask disposed between the plurality of vapor deposition source openings and the substrate, and a control plate unit that includes a plurality of control plates disposed along a first direction orthogonal to a normal line direction of the substrate and that is disposed between the vapor deposition source and the vapor deposition mask, the vapor deposition particles that have passed through a space between the control plates adjacent in the first direction and a plurality of mask openings formed in the vapor deposition mask are caused to adhere onto the substrate while one of the substrate and the vapor deposition unit is moved relative to the other along a second direction orthogonal to the normal line direction of the substrate and the first direction in a state in which the substrate and the vapor deposition mask are spaced apart at a fixed interval, and the method further comprises: a step of detecting a difference in an amount of thermal expansion in the first direction between the vapor deposition source and the control plate unit; and a step of correcting the difference in the amount of thermal expansion.
