摘要:
A method for providing a topographical pattern on a conducting or semiconducting carrier element of an ECPR master electrode is provided. The method comprises the steps of providing an etch mask on a front side of said carrier element; and etching said front side of said carrier element according to an reactive ion etch sequence, wherein said sequence comprises i) etching a first part of a trench of said carrier element using a predetermined set of constant etch parameters, and ii) etching a second part of said trench using a repeated cycle of a predetermined set of alternating etch parameters.

Methods for separating a master electrode (101, 201) and a substrate (102, 202) in an ECPR process after printing are disclosed. The master electrode (101, 201) or the substrate (102, 202) is arranged on a first chuck (103, 104, 203, 204) and the other one of said master electrode (101, 201) and the substrate (102, 202) is arranged on a second chuck (103, 104, 203, 204. The master electrode (101, 201) and substrate (102, 202) have a planar interaction area during plating.
摘要:
An electrode for forming an electrochemical cell with a substrate and a method of forming said electrode. The electrode comprises a carrier (1) provided with an insulating layer (7) which is patterned at a front side. Conducting material in an electrode layer (4) is applied in the cavities of the patterned insulating layer and in contact with the carrier. An connection layer (5) 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.
摘要:
A chuck (500) for holding a master electrode or a substrate during an electrochemical pattern replication (ECPR) process is provided. The chuck comprises an interaction surface (506) on which the master electrode or the substrate is arranged, and attaching means for clamping said master electrode or said substrate to said interaction surface, such that said master electrode or said substrate is substantially conforming to the shape of said interaction surface (506) in a resting position. The chuck is provided with a void (504) proximally of the interaction surface (506), and a pressure channel (507) communicating with said void (504), such that an over pressure in said void (504) brings said interaction surface (506) into convex shape, such that said master electrode or said substrate arches distally in said resting position.
