Publication number: 20230386809Abstract: A magnetic shield reduces external noise in a chamber including a target and at least one electromagnet for copper physical vapor deposition (PVD). The shield may have a thickness in a range from approximately 0.1 mm to approximately 10 mm to provide sufficient protection from radio frequency and other electromagnetic signals. As a result, copper atoms in the chamber undergo less re-direction from external noise. Additionally, even when hardware failure occurs during PVD (e.g., an electromagnet malfunctions, a wafer stage is not level, and/or a flow optimizer induces too much shift, among other examples), the copper atoms are less susceptible to small re-directions from external noise. As a result, back end of line (BEOL) and/or middle end of line (MEOL) conductive structures are formed in a more uniform manner, which increases conductivity and improves lifetime of an electronic device including the BEOL and/or MEOL conductive structures.Type: ApplicationFiled: August 10, 2023Publication date: November 30, 2023Inventors: Chia-Hung TSAI, Chin-Szu LEE, Szu-Hua WU, Jui-Hung HO, Chi-Hung LIAO, Yu-Jen CHIEN
