Abstract:
1. A method for forming a device structure comprising: selecting an insulating substrate having a carbon-based nanostructure layer on an upper surface; forming a first layer of a first metal on said carbon-based nanostructure layer; forming a first patterned layer having a first pattern on said first layer of a first metal; transferring said first pattern to said first layer of a first metal and said carbon-based nanostructure layer to form a first patterned layer of a first metal and a first patterned carbon-based nanostructure layer there under; removing said first patterned layer; forming a second patterned layer of a second metal over said insulating substrate and said first patterned layer of a first metal; said second patterned layer of a second metal having a second pattern comprising a plurality of contacts spaced apart from one another wherein respective contacts have a portion on said first patterned layer of a first metal and a portion on said insulating substrate; and removing said first patterned layer of a first metal where not covered by said plurality of contacts whereby said first patterned carbon-based nanostructure layer has regions not covered by said first patterned layer of first metal.
