Abstract: A bonding device has two chucks, two gas pressure regulators and a control unit. The chucks each have a holding surface with pressure ports fluidically connected to the respective gas pressure regulator. The control unit is electrically and/or wirelessly connected to the gas pressure regulators and configured to control gas pressure regulators independently from each other. Support elements movably mounted within the pressure ports, are provided to measure the amount of substrate deflection and adjust the respective gas pressures and also to apply additional mechanical pressure to the substrates. The two chucks may be mounted on corresponding support structures so as to be thermally isolated therefrom. The temperature of the two chucks may be equalised by moving the chucks into contact. A chuck tempering device may be used for equalising the temperature of the two chucks. The bonding device is used for bonding two substrates by bonding wave propagation.

In particular, the substrate is mechanically supported at its peripheral or edge portion, namely in the non-active area of the substrate, only; an additional non-mechanical extended support is provided in the active area by a gas cushion. The gas cushion is generated by a controllable nozzle or purge for a distinct and controlled compensation of the downward deflection of the substrate.
