Patent ID: 7005046

Claim:
A system for electroplating semiconductor substrates, comprising: a mainframe comprising: two or more electrolytic plating cells; an electrolyte reservoir; a supply line that is in fluid communication with at least one of the two or more electrolytic plating cells and a bypass line that is in fluid communication with the electrolyte reservoir; and a pump that is in fluid communication with the supply line and the electrolyte reservoir, wherein the pump is adapted to deliver a fluid from the electrolyte reservoir to the supply line; and a dosing system platform positioned a distance from the mainframe, wherein the dosing system platform comprises: an electrolyte fluid line having an inlet that is in fluid communication with the supply line and an outlet that is in fluid communication with the electrolyte reservoir; and two or more additive sources connected to the electrolyte fluid line that are adapted to dose two or more additives into a fluid flowing through the electrolyte fluid line.
