Latest Patents

Lin Zhu's latest patents include innovative methods aimed at reducing particulate emissions during sputtering. One of his patents, titled "Sputter targets and methods of manufacturing same to reduce particulate emission during sputtering," discloses techniques for minimizing inclusion content in sputter targets. This is achieved by adding a small amount of silicon to molten aluminum or aluminum alloys, followed by filtering the molten metals through a filter medium. The resulting targets, which contain substantially no inclusions greater than about 400 micrometers, are particularly beneficial for sputtering applications, as they lead to a reduction in macroparticles on substrates.

Another significant patent is "Method for determining a critical size of an inclusion in aluminum or aluminum alloy sputtering target." This invention outlines a method for determining the critical size of an aluminum oxide inclusion in sputter targets to prevent arcing during the sputtering process. The method involves using a sputtering apparatus with an argon plasma, where the thickness of the plasma sheath is known. By ensuring that the diameter of the aluminum oxide inclusion is less than the thickness of the plasma sheath, arcing can be inhibited, enhancing the efficiency of the sputtering process.
