This application is a continuation of U.S. application Ser. Nos. 11/028,960 and 11/029,219 which were both filed Jan. 3, 2005. These two applications claim benefit of U.S. Application. Nos. 60/582,689; 60/582,690; 60/609,719; 60/611,789; 60/540,511; 60/533,933; 60/536,865; and 60/533,947 and are a continuations-in-part of U.S. patent application Ser. No. 10/949,738 which in turn is a continuation-in-part of U.S. patent application Ser. No. 10/772,943, which in turn claims benefit of U.S. Application Nos. 60/445,186; 60/506,015; 60/533,933; and 60/536,865; furthermore the '738 application claims benefit of U.S. Application Nos.: 60/506,015; 60/533,933; and 60/536,865. Each of these applications is incorporated herein by reference as if set forth in full herein including any appendices attached thereto.

Another example of a CC mask and CC mask plating is shown in FIGS. 1D-1G. FIG. 1D shows an anode 12′ separated from a mask 8′ that includes a patterned conformable material 10′ and a support structure 20. FIG. 1D also depicts substrate 6 separated from the mask 8′. FIG. 1E illustrates the mask 8′ being brought into contact with the substrate 6 . FIG. 1F illustrates the deposit 22′ that results from conducting a current from the anode 12′ to the substrate 6. FIG. 1G illustrates the deposit 22′ on substrate 6 after separation from mask 8′. In this example, an appropriate electrolyte is located between the substrate 6 and the anode 12′ and a current of ions coming from one or both of the solution and the anode are conducted through the opening in the mask to the substrate where material is deposited. This type of mask may be referred to as an anodeless INSTANT MASK™ (AIM) or as an anodeless conformable contact (ACC) mask.
BRIEF DESCRIPTION OF THE DRAWINGSi
FIG. 25A depicts an alternative mounting structure configuration while FIGS. 25B and 25 C depict two alternative configurations for locating the mounting structures in forming arrays of various pitch.
