Patent number: 12051622Abstract: A method includes forming a patterned mask comprising a first opening, plating a conductive feature in the first opening, depositing a passivation layer on a sidewall and a top surface of the conductive feature, and patterning the passivation layer to form a second opening in the passivation layer. The passivation layer has sidewalls facing the second opening. A planarization layer is dispensed on the passivation layer. The planarization layer is patterned to form a third opening. After the planarization layer is patterned, a portion of the planarization layer is located in the second opening and covers the sidewalls of the passivation layer. An Under-Bump Metallurgy (UBM) is formed to extend into the third opening.Type: GrantFiled: December 4, 2020Date of Patent: July 30, 2024Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING CO., LTD.Inventors: Ming-Da Cheng, Tzy-Kuang Lee, Hao Chun Liu, Po-Hao Tsai, Chih-Hsien Lin, Ching-Wen Hsiao
