Patent number: 9490205Abstract: A copper alloy layer is blanket deposited over a low k dielectric layer and in via openings within the low k dielectric layer. The blanket deposited layer is then anisotropically etch to form horizontal interconnects. The interconnects are annealed to form a metal oxide barrier lining. A second low k dielectric layer is then depositing over the horizontal interconnects. Air gaps can be formed between adjacent interconnects to lower parasitic capacitance therebetween.Type: GrantFiled: May 15, 2015Date of Patent: November 8, 2016Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Cheng-Hsiung Tsai, Chung-Ju Lee, Tsung-Jung Tsai, Hsiang-Huan Lee, Ming-Han Lee
