  • Publication number: 20230343637
    Abstract: Multiple dry etching operations are performed to form an opening for an interconnect structure, with a wet cleaning operation performed in between the dry etching operations. This multi-step etch approach increases the effectiveness of residual material removal, which increases the quality of the interconnect structure and reduces the likelihood of under etching, both of which increase semiconductor device yield and semiconductor device performance.
