(193a) Transfer Printing of Organic-Inorganic Multilayer Thin Films

Micro-contact printing is a form of soft lithography that uses mechanical contact of an elastomer stamp to transfer "ink" materials from a donor substrate to a receiving substrate. It relies on the diffusion or adhesion via van der Waals forces of the "ink" materials during conformal large-area contact between the polymeric stamp and substrates. Due to its high resolution, scalability, and compatibility with both organic and inorganic materials, the technique has a potential to serve as a complimentary. micro/nano-scale patterning method to traditional photolithography. This work demonstrates transfer printing of micro-scale arrays of organic-inorganic multilayers using patterned donor substrate and polymeric stamp. Organic and inorganic thin film stacks are deposited onto the donor substrate via physical vapor deposition (PVD), picked up with the stamp, and released to receiving substrate. During the printing process, temperature is controlled accordingly to take advantage of change in mechanical properties of the polymeric stamp to control adhesive behavior.
