Patent ID: 7713773

Claim:
A method of depositing a stacked layer of a plurality of films in a plurality of sequentially disposed depositing units onto a continuously moving roll-to-roll sheet comprising the steps of: continuously moving the roll-to-roll sheet through each of the plurality of sequentially disposed depositing units so that continuous portions of a top surface of the roll-to-roll sheet are positioned for depositing to occur thereon when disposed in each of the depositing units; and continuously depositing each one of the films onto the top surface of the roll-to-roll sheet as the roll-to-roll sheet moves through electroplating the units, the plurality of films sequentially including: a contact layer comprising a bottom metal film, a top metal film, and at least one intermediate film between the bottom metal film and the top metal film, wherein the bottom film comprises at least one of Zn, Cu, Ni and Co, wherein the top metal film comprises at least one of Ru, Os and Ir, and wherein the at least one intermediate film comprises at least one of Zn, Cu, Ni and Co; and a precursor layer comprising at least one Group IB material film and at least one Group IIIA material film, wherein the step of continuously depositing deposits all of the films by at least one of electroplating and electroless plating, and wherein each of the depositing units is one of electroplating and electroless plating depositing units.
