摘要:
A method of electrochemical deposition (ECD) provides a barrier and a seed layer on a substrate. The surfaces of the substrate are pre-treated before a metal layer is electrochemically deposited thereon in an electrochemical plating cell with a physical or a chemical surface treatment process. The electrochemical plating cell is covered by a cap to prevent evaporation of the electrolyte solution. The electrochemical plating cell includes a substrate holder assembly with a lift seal, e.g., with a contact angle θ less than 90° between the lift seal and the substrate. The substrate holder assembly includes a substrate chuck at the rear side of the substrate.
