Method of transferring thin film
First Claim
1. An adhesive-free method of transferring a thin film from a first substrate to a second substrate comprising the steps of:
- (a) providing a transfer structure, wherein the transfer structure comprises a support layer and a film contact layer, and wherein the support layer comprises an elastomer and has a Young'"'"'s modulus of 300 kPa-10 MPa, the elastomer being selected from a group consisting of;
poly(dimethylsiloxane), polyurethane, butadiene-acrylonitrile copolymer, perfluoroalkoxy polymers, polyethylene, poly(ethyl acrylate), polyisoprene, polybutadiene, polychloropene, and combinations thereof;
(b) providing a thin film on a surface of a first substrate;
(c) contacting the film contact layer of the transfer structure with the thin film;
(d) removing the first substrate to obtain the transfer structure with the thin film in contact with the film contact layer;
(e) supporting the thin film on the film contact layer with the support layer which the thin film is in contact with the film contact layer after step (d) and prior to step (f);
(f) contacting the transfer structure after step (e) with a surface of a second substrate;
(g) removing the film contact layer and the support layer, wherein the removing comprises dissolving the film contact layer; and
(h) obtaining the thin film on the surface of the second substrate after step (g), wherein steps (a) through (h) are performed without use of adhesives.

Abstract
The present invention discloses a method for transferring a thin film from a first substrate to a second substrate comprising the steps of: providing a transfer structure and a thin film provided on a surface of a first substrate, the transfer structure comprising a support layer and a film contact layer, wherein the transfer structure contacts the thin film; removing the first substrate to obtain the transfer structure with the thin film in contact with the film contact layer; contacting the transfer structure obtained with a surface of a second substrate; and removing the film contact layer, thereby transferring the thin film onto the surface of the second substrate.
