Large [[Integrated circuit|circuit]]s made with [[thin-film transistor]]s and other devices can be [[pattern]]ed onto these large substrates, which can be up to a few metersmetres wide and {{convert|50|km|abbr=on}} long.{{citation needed|date=March 2017}} Some of the devices can be patterned directly, much like an [[inkjet printer]] deposits ink. For most [[semiconductor]]s, however, the devices must be patterned using [[photolithography]] techniques.

Roll-to-roll processing of large-area electronic devices reduces manufacturing cost.<ref>{{cite book|chapter-url=https://books.google.com/books?id=ZiGjrlkSpOQC&q=%22web+processing%22+%22Roll+to+roll%22&pg=PA19|title=Flexible Electronics: Materials and Applications|chapter=Fabrication on Web by Roll-to-Roll Processing|page=19|editor1=Wong, William S. |editor2=Salleo, Alberto|publisher=Springer|place=New York, NY|year=2009|isbn=978-0387743639}}</ref><ref name=":0" /> Most notable would be [[solar cell]]s, which are still prohibitively expensive for most markets due to the high cost per unit area of traditional bulk ([[Monocrystalline silicon|mono-]] or [[Polycrystalline silicon|polycrystalline]]) silicon manufacturing. Other applications could arise which take advantage of the flexible nature of the substrates, such as electronics embedded into clothing, large-area flexible displays, and [[rollable display|roll-up portable displays]].
