Abstract:
A method and a device for bonding a first substrate with a second substrate inside a sealed bonding chamber. The method includes: a) fixing of the first and second substrates, b) arranging of the first and second substrates, c) mutual approaching of the first and second substrates, d) contacting the first and second substrates at respective bond initiation points, e) generating a bonding wave running from the bond initiation points to side edges of the substrates, and f) influencing the bonding wave during course of the bonding wave, wherein targeted influencing of the bonding wave takes place by a regulated and/or controlled change of pressure inside the bonding chamber.
