  • Patent number: 6673189
    Abstract: A method for producing a re-releasable bond between two wafers which is stable at high temperatures and mechanically stable is described. The two wafers to be bonded are placed one on top of the other in such a way that a surface of the first wafer is disposed on a surface of the second wafer. Interspaces at least partially connecting the surfaces are created between the wafers. A liquid glass compound is introduced into the interspaces in such a way that a liquid glass film wetting the inner surfaces of the interspaces is formed, in which process voids that are connected to the atmosphere surrounding the wafers remain inside the interspaces wetted with the liquid glass compound. To transform the wetting liquid glass film into a solid silicon dioxide film, the wafers lying one on top of the other are subjected to a temperature treatment.
