Abstract
A surface treatment apparatus applies a hydrophilic treatment to a bonding surface of a target object bonded to a bonded object using hydrogen bonding, the hydrophilic treatment being applied prior to the bonding. The surface treatment apparatus includes a support base and a spray nozzle. The support base supports a surface of the target object opposite to the bonding surface, the target object being one or more target objects. The spray nozzle causes dew condensation temporarily on the bonding surface by spraying, onto the bonding surface of the target object supported by the support base, humidified air having a water vapor pressure equal to or higher than a saturated water vapor pressure corresponding to a temperature of the bonding surface.
