Claim:
A method of patterning a substrate, comprising the sequential steps of: a) providing a pre-formed first masking film and a pre-formed first removal film; b) physically locating the pre-formed first masking film over the substrate; c) segmenting the located pre-formed first masking film into a first masking portion and one or more first opening portions in first locations and physically locating the pre-formed first removal film over the first masking portion and first opening portions; d) adhering one or more of the first opening portions to the located pre-formed first removal film; e) picking up and removing the located pre-formed first removal film and one or more of the first opening portions adhered to the located pre-formed first removal film to form one or more first openings in the located pre-formed first masking film; and f) depositing first materials over the substrate through the first openings in the located pre-formed first masking film; g) providing a pre-formed second masking film and then physically locating the pre-formed second masking film over the located pre-formed first masking film and first openings, wherein the pre-formed second masking film is not formed inside the first openings; h) segmenting the located pre-formed second masking film into a second masking portion and one or more second opening portions in second locations and physically locating a pre-formed second removal film over the second masking portion and second opening portions; i) adhering one or more of the second opening portions to the located pre-formed second removal film; j) picking up and removing the located pre-formed second removal film and one or more of the second opening portions adhered to the located pre-formed second removal film to form one or more second openings in the located pre-formed second masking film; and k) depositing second materials over the substrate through the second openings in the located pre-formed second masking film; l) picking up and removing the first masking portion and second masking portion.
