Abstract: A method includes forming a first sealing layer at a first edge region of a first wafer; and bonding the first wafer to a second wafer to form a wafer stack. At a time after the bonding, the first sealing layer is between the first edge region of the first wafer and a second edge region of the second wafer, with the first edge region and the second edge region comprising bevels. An edge trimming process is then performed on the wafer stack. After the edge trimming process, the second edge region of the second wafer is at least partially removed, and a portion of the first sealing layer is left as a part of the wafer stack. An interconnect structure is formed as a part of the second wafer. The interconnect structure includes redistribution lines electrically connected to integrated circuit devices in the second wafer.
