Abstract:
1. A system of fabricating a flexible electrode array, comprising the steps of: spin-coating a poly(dimethylsiloxane) layer (PDMS) onto a handle wafer that has been pre-coated with a conductive seed layer; patterning said poly(dimethylsiloxane) layer to expose said conductive seed layer to form electrodes; plating a material for said electrodes until said electrodes are higher than a thickness of said poly(dimethylsiloxane) layer and until said electrodes form mushroom caps which later will prevent said electrodes from popping out of said poly(dimethylsiloxane) layer when said poly(dimethylsiloxane) layer is removed from said handle wafer; and patterning conducing lines on said poly(dimethylsiloxane) layer.
