Patent ID: 8703406

Claim:
A method of forming a master, comprising: creating an original master pattern for replication of dissoluble patterned templates; providing a base substrate with an etchable coating layer thereon, the base substrate having an area larger than the original master pattern; applying and patterning a photoresist layer over the base substrate so as to leave open a first portion of the etchable coating layer and to cover a second portion of the etchable coating layer with the photoresist layer; contacting a dissoluble patterned template onto the first portion of the etchable coating layer to adhere a patterned functional material to the coating layer, then dissolving the template and dry etching the residual layer of the functional material to expose the coating layer in correspondence to the pattern; etching the coating layer in areas neither covered by the photoresist layer nor the functional material so as to transfer a pattern to the first portion of the coating layer; removing the photoresist layer and the functional material; applying and patterning a second photoresist layer over the base substrate so as to leave open the second portion of the etchable coating layer and to cover the first portion of the coating layer and its transferred pattern with the photoresist layer; contacting another dissoluble patterned template onto the second portion of the etchable coating layer in a specified alignment with the transferred pattern of the first portion so to adhere a patterned functional material to the second portion of the coating layer, then dissolving the template and dry etching the residual layer of the functional material to expose the coating layer in correspondence to the pattern; etching the coating layer in areas neither covered by the second photoresist layer nor the functional material so as to transfer a pattern to the second portion of the coating layer; and removing the photoresist layer and the functional material.
