With a total of 5 patents to his name, Frach's work has advanced the understanding and application of magnetron sputtering techniques.
Latest Patents
Frach's latest patents include a method for depositing a layer using a magnetron sputtering device. This method involves depositing a layer on a substrate inside a vacuum chamber using at least two magnetron cathodes, each equipped with one target. The process includes the introduction of both working and reactive gases into the vacuum chamber. In the first phase, a pulsed negative direct current voltage is applied to each magnetron cathode, operated in push-pull mode. The second phase involves switching the pulsed direct current voltages between the magnetron cathode and an additional electrode, with an electric voltage applied to the substrate.
Another significant patent is related to the deposition of a piezoelectric film containing aluminum nitride (AlN). This method utilizes magnetron sputtering of at least two targets, with a mixture of reactive nitrogen gas and an inert gas introduced into the vacuum chamber. The process alternates between unipolar and bipolar pulse modes to achieve the desired film properties.
