Abstract In one aspect, a method includes heating a wafer chuck, heating a first wafer, depositing a first epoxy along at least a portion of a surface of the first wafer disposed on the wafer chuck, spinning the wafer chuck to spread the first epoxy at least partially across the first wafer, placing a second wafer on the first epoxy disposed on the first wafer and bonding the second wafer to the first epoxy under vacuum to form a two-wafer-bonded structure.
