A jet nozzle ejects a high-speed, high-pressure liquid or water. The jet thrusts into the bonded substrate through a guide unit. The position in the x-axis direction of this guide unit is adjusted by a motor such that the jet is concentrated into the bonding interface of the bonded substrate stack.
