发明名称 Method for molecular adhesion bonding at low pressure
摘要 A method for bonding first and second wafers by molecular adhesion. The method includes placing the wafers in an environment having a first pressure (P1) greater than a predetermined threshold pressure above which initiation of bonding wave propagation is prevented, bringing the first wafer and the second wafer into alignment and contact, and spontaneously initiating the propagation of a bonding wave between the wafers after they are in contact solely by reducing the pressure within the environment to a second pressure (P2) below the threshold pressure.

主权项 1. A method for bonding at least a first wafer and a second wafer by molecular adhesion, which comprises: placing the first and second wafers in an environment having a first pressure (P1) greater than a predetermined threshold pressure above which initiation of a bonding wave propagation is prevented, and then bringing the first wafer and the second wafer into alignment and contact; and spontaneously initiating the propagation of a bonding wave between the first and second wafers after the wafers are in contact solely by reducing the pressure within the environment to a second pressure (P2) below the threshold pressure.
