Abstract
A bonding method includes attracting and holding a first substrate by using a first holder; attracting and holding a second substrate by using a second holder; and forming a combined substrate by moving the first holder and the second holder relative to each other to bring the first substrate and the second substrate into contact with each other. The bonding method includes heating the first substrate and the second substrate or the combined substrate; and cooling the heated combined substrate by using a cooling unit. In the cooling, bending of the combined substrate is controlled by forming a temperature difference in the combined substrate.
