Abstract

An implantable electrode system of is disclosed that includes a conductive electrode layer, an interconnect coupled to the electrode layer, an insulator that insulates the interconnect, and an anchor that more securely fixes the electrode layer in place. This structure is particularly useful with the electrode layer being a neural interface that is configured to provide either a recording or stimulating function. A method for forming such an implantable electrode system includes forming an interconnect over a base layer, forming an anchoring structure over the base layer, depositing an insulating material layer over the interconnect structure and over the anchoring structure, exposing a portion of the interconnect structure, forming an electrode layer over the insulating layer, the electrode layer contacting the exposed portion of the interconnect structure.
