SUBSTRATE BONDING METHOD AND SUBSTRATE BONDING APPARATUS

摘要

According to one embodiment, there is provided a substrate bonding method. The substrate bonding method includes disposing a first substrate and a second substrate to face each other. The substrate bonding method includes controlling the first substrate and the second substrate to have a temperature difference. The substrate bonding method includes, in a state where the first substrate and the second substrate are controlled to have the temperature difference, bonding the first substrate to the second substrate by bringing the first substrate into contact with the second substrate while deforming the first substrate so that a central portion of the first substrate is projected toward the second substrate. The central portion of the first substrate is on an inner side of a peripheral portion of the first substrate.
