Patent ID: 7635609

Claim:
A method of patterning a substrate, comprising: a) providing a separately formed first masking film and then mechanically placing the first masking film over the substrate; b) segmenting the first masking film into at least two separate detached masking film portions, a first masking portion and one or more first opening portions in first locations, each first location covering two or more different, non-contiguous operable areas and at least one inoperable area over the substrate; c) mechanically peeling the one or more first opening portions intact from the substrate to thereby expose each of the first locations; d) depositing first materials over the substrate in the first locations to form first patterned areas; e) providing a separately formed second masking film and then mechanically locating the second masking film over the substrate and first masking portions; f) segmenting the second masking film and first masking portion into at least two separate detached masking film portions, a second masking portion and one or more second opening portions, wherein the second opening portions are in one or more second locations over the substrate, yet different from the first locations, each second location covering two or more different, non-contiguous operable areas and at least one inoperable area over the substrate; g) mechanically peeling the one or more second opening portions intact from the substrate to thereby expose each of the second locations; and h) depositing second materials over the substrate in the second locations to form second patterned areas.
