A method for manufacturing a flexible circuit electrode array, is: deposit a metal trace layer on an insulator polymer base layer; apply a layer of photoresist on the metal trace layer and pattern the metal trace layer and form metal traces on the insulator polymer base layer; activate the insulator polymer base layer and deposit a top insulator polymer layer and form a single insulating polymer layer with the base insulator polymer layer; wherein the insulator polymer layers are heated at 80-150° C. and then at 230-350° C.

A position detecting device is disclosed for use with a position indicator. The position detecting device includes a coil substrate, a magnetic path material, and a shield material. A coil for generating an alternating magnetic field for electromagnetic coupling with the position indicator is disposed on the coil substrate. The magnetic path material is composed of a material having such permeability as not to disturb direct current magnetic flux but to form a magnetic path for the alternating magnetic field generated by the coil, and having predetermined electrical resistance for suppressing flow of an eddy current in order to enhance the material's performance as a magnetic path. The shield material is a non-magnetic substance that does not disturb the direct current magnetic flux due to the direct current magnetic field and that has electrical conductivity for generating an eddy current based on the alternating magnetic field.

A method of manufacturing a flexible circuit electrode array that provides excellent adhesion between the polymer base layer and the polymer top layer and insulation of the trace metals and electrodes. A layer of polymer is laid down. A layer of metal is applied to the polymer and patterned to create electrodes and leads for those electrodes. A second layer of polymer is applied over the metal layer and patterned to leave openings for the electrodes, or openings are created later by means such as laser ablation. Hence the array and its supply cable are formed of a single body. Alternatively, multiple alternating layers of metal and polymer may be applied to obtain more metal traces within a given width.
