Publication number: 20230377956Abstract: A method of forming a semiconductor device structure is disclosed. First and second etch stop layers are formed overlying a semiconductor structure having a conductive feature formed therein. A dielectric layer is formed overlying the second etch stop layer, and a hard mask, that comprises a tungsten-based material, is formed overlying the dielectric layer, and patterned. A resist layer is formed over the patterned hard mask. Using the patterned resist layer as a mask, a first etching process is performed to form a via opening that extends partially through the dielectric layer. Using the patterned hard mask as an etch mask, a second etching process (e.g., dry etching process) is performed to extend the via opening through the second etch stop layer, and a third etching process (e.g., wet etching process) is performed to extend the via opening through the first etch stop layer to reach the conductive feature.Type: ApplicationFiled: May 23, 2022Publication date: November 23, 2023Applicant: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chien-Han Chen, Shih-Yu Chang, Chien-Chih Chiu, Huang-Ming Chen
