Abstract:
A method of patterning first conductive lines in a first layer and second conductive lines in a second layer, the first conductive lines being connected to the second conductive lines, the method comprising:applying a first copper plating catalyst to a material surface of a material in a first pattern by stamping; providing a first copper solution over the first copper plating catalyst whereby the first conductive lines are formed; applying a second copper plating catalyst to the material surface and the first conductive lines in a second pattern by stamping, the first pattern having a different orientation or being a different pattern than the second pattern; providing a second copper solution over the second copper plating catalyst, whereby the second conductive lines are formed, the first conductive lines being electrically coupled to the second conductive lines at intersections of the first conductive lines and the second conductive lines; providing a first non-critical photolithographic mask layer above the first and second conductive lines; patterning the first non-critical photolithographic mask layer to provide first apertures exposing the first and second conductive lines; and removing at least one of the first conductive lines or the second conductive lines at the location of the first apertures.
