Claim Text:
1. A method of joining a target substrate and a support substrate, the method comprising: an adhesive coating operation that includes coating the target substrate or the support substrate with an adhesive; an adhesive removing operation that includes supplying a solvent for removing the adhesive onto an outer peripheral portion of the target substrate or the support substrate, which is coated with the adhesive in the adhesive coating operation, to thereby remove the adhesive on the outer peripheral portion; a first heat processing operation that includes heating the target substrate or the support substrate, in which the adhesive on the outer peripheral portion is removed, at a first predetermined temperature; and a joining operation that includes pressing and joining the target substrate, in which the adhesive on the outer peripheral portion is removed in the adhesive removing operation, and the support substrate coated with no adhesive, or pressing and joining the support substrate, in which the adhesive on the outer peripheral portion is removed in the adhesive removing operation, and the target substrate coated with no adhesive while performing a second heat processing operation on at least the target substrate or the support substrate at a second predetermined temperature, wherein, in the adhesive removing operation, a predetermined distance of the outer peripheral portion from an outer lateral side of the target substrate or the support substrate is determined based on a type of the adhesive, a target film thickness of the adhesive with which the target substrate or the support substrate is coated in the adhesive coating operation, a heat processing temperature at which the target substrate or the support substrate is heated in the first heat processing operation or the joining operation, and a pressure at which the target substrate and the support substrate are pressed in the joining operation.
