Abstract
An electrode for forming an electrochemical cell with a substrate and a method of forming said electrode. The electrode comprises a carrier provided with an insulating layer which is patterned at a front side. Conducting material in an electrode layer is applied in the cavities of the patterned insulating layer and in contact with the carrier. A connection layer is applied at the backside of the carrier and in contact with the carrier. The periphery of the electrode is covered by the insulating material.
Claims20
A method of forming a master electrode, comprising:
- providing a disc of at least one layer of a conducting and/or semi-conducting material;
- forming an insulating pattern layer at least partly of at least one layer of an insulating material;
- forming at least one recess in said insulating material;
- forming a conducting electrode layer of an electrode forming, conducting material in each recess;
- and
- forming at least one recess at the back side of said insulating pattern layer.
A master electrode for forming an electrochemical cell with a substrate, comprising:
- a disc of at least one layer of a conducting and/or semi-conducting material;
- an insulating pattern layer at least partly of at least one layer of an insulating material;
- said insulating pattern layer at a front side thereof being provided with at least one recess, each being provided with a conducting electrode layer of an electrode forming, conducting material;
- said insulating pattern layer at a back side being provided with at least one recess;
- and
- an electrical seed layer connection of a conducting, electrode forming material and arranged in at least some parts between the recesses on top of said insulating pattern layer;
- wherein the disc is provided with recesses in the same region as recesses of the insulating pattern layer, said recesses of the disc being provided with a conducting electrode layer;
- and
- wherein said electrical seed layer connection is electrically isolated by an insulating material from the conducting or semiconducting materials of the disc, the conducting electrode layer, or the connection layer.
