Abstract
A method of making a circuit with raised features includes the steps of: forming a mandrel having a plurality of depressions therein; coating said mandrel and depressions with a coating that is readily separable from the mandrel and said depressions; forming a pattern of circuit traces on said coating and in a first subset of said depressions; forming a substrate on said traces; adding a material to said coating at least in a second set of said depressions not containing circuit traces; removing said traces, said substrate, said material and said coating from said mandrel wherein a plurality of raised features project from a plane of said circuit traces; and removing the coating from said traces, said raised features, said material and said substrate, wherein a first subset of said raised features comprises conductive raised features and wherein a second subset of said raised features comprises nonconductive raised features.
