Latest Patents
One of Andrew Cahill's latest patents is titled "Stress compensation and relief in bonded wafers." This patent discloses a process for manufacturing individual die devices with a desired amount of flatness from a bonded wafer process. The flatness of a bonded wafer is measured at a specific point in the manufacturing process. This measurement is then compared to a predetermined value derived from empirical analysis of previous devices made using the same process. If the flatness does not meet the predetermined value, compensation layers are added to achieve the desired flatness. Once the flatness is obtained, subsequent processing is performed to yield individual dies with the desired characteristics.
Another significant patent by Cahill is "Wafer stacking to form a multi-wafer-bonded structure." This method involves heating a wafer chuck and a first wafer, depositing epoxy on the surface of the first wafer, and spinning the wafer chuck to spread the epoxy. A second wafer is then placed on the first epoxy and bonded under vacuum to create a two-wafer-bonded structure. This innovative approach enhances the efficiency and effectiveness of wafer bonding processes.
