BONDING SYSTEM, BONDING METHOD, PROGRAM AND COMPUTER STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To bond a processed substrate and a support substrate appropriately.SOLUTION: A bonding system 1 for bonding a processed wafer W and a support wafer S includes bonding devices 31-33 for bonding a processed wafer W and a support wafer S via an adhesive, and a heat treatment device 30 performing heat treatment of a superimposed wafer T bonded by the bonding device 31-33 so that the outer peripheral part of the superimposed wafer T is heat treated at a higher temperature than the central part. The heat treatment device 30 has an annular heating mechanism for heating the outer peripheral part of the superimposed wafer T. The heat treatment device 30 can house a plurality of superimposed wafers T and can perform heat treatment thereof. The interior of the heat treatment device 30 can be maintained in inert gas atmosphere.
