Electronic device fabrication on non-conductive polymer substrate

Abstract

A process for fabricating an electronic device on a non-conductive polymer substrate, particularly from the family of polyaniline, comprises applying a covalent doping agent, such as an R.sup.+ donor compound, where R is an organic group, e.g., methyl iodide, to a preselected portion of a base-type non-conductive polymer substrate containing carbon-nitrogen linkages, and converting such preselected portion of the polymer substrate to an electrically conductive polymer portion, by covalent linkage of the R groups of such donor compound, to nitrogen atoms of the non-conductive polymer substrate. Electronic devices, such as resistors, capacitors, inductors, printed circuits and the like, can be provided by the invention process, in the form of light-weight polymers containing no metal, and which are stable and wherein the conductive portions are non-diffusing.
