发明名称 Anode slime reduction method while maintaining low current
摘要 Embodiments of the invention generally provide an electrochemical plating cell having an electrolyte container assembly configured to hold a plating solution therein, a head assembly positioned above the electrolyte container, the head assembly being configured to support a substrate during an electrochemical plating process, and an anode assembly positioned in a lower portion of the electrolyte container. The anode assembly generally includes a copper member having a substantially planar upper surface, at least one groove formed into the substantially planar upper surface, each of the at least one grooves originating in a central portion of the substantially planar anode surface and terminating at a position proximate a perimeter of the substantially planar upper surface, and at least one fluid outlet positioned at a perimeter of the substantially planar upper anode surface.
