  • Publication number: 20230238268
    Abstract: In some embodiments, the present disclosure relates to a method that includes aligned a first wafer with a second wafer. The second wafer is spaced apart from the first wafer. The first wafer is arranged on a first electrostatic chuck (ESC). The first ESC has electrostatic contacts that are configured to attract the first wafer to the first ESC. Further, the second wafer is brought toward the first wafer to directly contact the first wafer at an inter-wafer interface. The inter-wafer interface is localized to a center of the first wafer. The second wafer is deformed to gradually expand the inter-wafer interface from the center of the first wafer toward an edge of the first wafer. The electrostatic contacts of the first ESC are turned OFF such that the first and second wafers are bonded to one another by the inter-wafer interface.

  • Patent number: 11094575
    Abstract: In some embodiments, the present disclosure relates to a method for bonding a first wafer to a second wafer. The method includes aligning a first wafer with a second wafer, so the first and second wafers are vertically stacked and have substantially planar profiles extending laterally in parallel. The method further includes bringing the first and second wafers into direct contact with each other at an inter-wafer interface. The bringing of the first and second wafers into direct contact includes deforming the first wafer so that the first wafer has a curved profile and that the inter-wafer interface is localized to a center of the first wafer. The second wafer maintains its substantially planar profile throughout the deforming of the first wafer. The method further includes deforming the first wafer and/or the second wafer to gradually expand the inter-wafer interface from the center to an edge of the first wafer.

  • Patent number: 10155369
    Abstract: The present disclosure relates to a method for debonding a pair of bonded substrates. In the method, a debonding apparatus is provided comprising a wafer chuck, a flex wafer assembly, and a set of separating blades. The pair of bonded substrates is placed upon the wafer chuck so that a first substrate of the bonded substrate pair is in contact with a chuck top surface. The flex wafer assembly is placed above the bonded substrate pair so that its first surface is in contact with an upper surface of a second substrate of the bonded substrate pair. A pair of separating blades having different thicknesses is inserted between the first and second substrates from edges of the pair of bonded substrates diametrically opposite to each other while the second substrate is concurrently pulled upward until the flex wafer assembly flexes the second substrate from the first substrate. By providing unbalanced initial torques on opposite sides of the bonded substrate pair, edge defects and wafer breakage are reduced.
