The specification describes a contact printing technique for forming patterns
of thin films with nanometer resolution over large areas. The procedure, termed
here "nanotransfer printing (nTP)", relies on tailored surface chemistries for
transferring thin films, typically metal films, from the raised regions of a stamp
to a substrate when these two elements are brought into intimate physical contact.
This technique is purely additive, it is fast (<15 s contact times), and the printing
occurs in a single processing step at room temperature in open air. nTP is capable
of producing patterns with a wide range of features with sizes down to 100
nm, and edge resolution better than 25 nm. Electrical contacts and interconnects
have been fabricated for high performance organic thin film transistors (TFTs)
and complementary inverter circuits, to demonstrate one of the many potential applications
for nTP.
