ABSTRACT:
Methods for fabricating conductive structures on and/or in interposing devices and microfeature devices that are formed using such methods are disclosed herein. In one embodiment, a method for fabricating interposer devices having substrates includes forming a plurality of conductive sections on a first substrate in a first pattern. The method continues by forming a plurality of conductive sections on a second substrate in a second pattern. The method further includes constructing a plurality of conductive lines in a common third pattern on both the first substrate and the second substrate. The conductive lines can be formed on the first and second substrates either before or after forming the first pattern of conductive sections on the first substrate and/or forming the second pattern of conductive sections on the second substrate.
