Abstract

A bonding system includes a surface modifying apparatus, a surface hydrophilizing apparatus and a bonding apparatus. The surface modifying apparatus is configured to modify a bonding surface of a first substrate and a bonding surface of a second substrate with plasma. The surface hydrophilizing apparatus is configured to hydrophilize the modified bonding surfaces of the first substrate and the second substrate. The bonding apparatus includes a condensation suppressing gas discharge unit, and is configured to bond the hydrophilized bonding surfaces of the first substrate and the second substrate by an intermolecular force. The condensation suppressing gas discharge unit is configured to discharge a condensation suppressing gas toward a space between a peripheral portion of the bonding surface of the first substrate and a peripheral portion of the bonding surface of the second substrate facing each other.
