Intrinsically conducting polymers (ICPs) represent a special class of materials with variable properties. Microstructuring of ICPs is possible by either pre- or poststructuring or direct microstructuring. The localization of both nucleation as well as the growth is important, especially for systems with a high negative aspect ratio. There are numerous microanalytical techniques for the characterization of electrochemical functionality, topography, stoichiometry and opto-electronic properties. Advantages and disadvantages are discussed for various laboratory techniques such as laser induced polymerization. Sharpness of ICP microstructures can be improved by combination of two or more localization techniques. The application of ICPs in the through-hole plating of printed circuit boards is discussed as an example of the technical production of a multiple microsystem with a high negative aspect ratio.
