FIG. 1 illustrates a perspective and partial sectional view of an exemplary electrochemical plating cell 100 of the invention. The plating cell 100 generally includes an outer basin 101 and an inner basin 102 positioned within the outer basin 101. The inner basin 102 is generally configured to contain a plating solution that is used to plate a metal, e.g., copper, onto a substrate during an electrochemical plating process. During the plating process, the plating solution is generally continuously supplied to the inner basin 102 (at about 1 gallon per minute for a 10 liter plating cell, for example), and therefore, the plating solution continually overflows the uppermost point of the inner basin 102 and runs into the outer basin 101. The overflow plating solution is then collected by the outer basin 101 and drained therefrom for recirculation into the inner basin 102. As illustrated in FIG. 1, the plating cell 100 is generally positioned at a tilt angle, i.e., the frame member 103 of the plating cell 100 is generally elevated on one side such that the components of the plating cell 100 are tilted between about 3° and about 30°. Therefore, in order to contain an adequate depth of plating solution within the inner basin 102 during plating operations, the uppermost portion of the inner basin 102 may be extended upward on one side of the plating cell 100, such that the uppermost point of the inner basin 102 is generally horizontal and allows for contiguous overflow of the plating solution supplied thereto around the perimeter of the inner basin 102.
With regard to other properties of the above noted membranes (Ionics, CMX, and Nafion®), each exhibit relatively high conductivity, i.e., about 41.2, 35.3, and 24.2 ohm cm2 at IOmA/cm2 for Ionics, Neosepta and Nafion®, respectively. Additional properties of the respective membranes are illustrated in Table 1.
