Publication number: 20240096609Abstract: The physical vapor deposition tool includes a magnet component, a single cathode, and a power circuit for biasing a pedestal that supports a semiconductor substrate. During a deposition operation that deposits an inert metal material, the physical vapor deposition tool may modulate an electromagnetic field emanating from the magnet component that includes spiral-shaped bands having different ranges of magnetic strength. The physical vapor deposition tool may have an increased throughput relative to a physical vapor deposition tool without the magnet component, the single cathode, and the power circuit. Additionally, or alternatively, the inert metal material may have a grain size that is greater relative to a grain size of an inert metal material deposited using the physical vapor deposition tool without the magnet component, the single cathode, and the power circuit.Type: ApplicationFiled: January 31, 2023Publication date: March 21, 2024Inventors: Yen-Liang LIN, Yu-Kang HUANG, Yu-Chuan TAI
