Abstract:
According to an embodiment of the present invention, an electrode sensor manufacturing method comprises: a step of providing a substrate having a metal thin film; a step of forming a resist layer on the substrate; a step of exposing part of a first electrode by patterning the lift-off resist layer; a step of forming an insulation layer on the substrate; a step of forming a well inside the insulation layer by removing the resist layer and the insulation layer on photoresist; and a step of forming a second electrode which is electrically connected with the first electrode inside the well. The electrode sensor manufacturing method can prevent the damage to the first electrode, and can reduce the impedance of the electrode due to the increasing surface area of the electrode by the second electrode.
