US 2003/0148196 A1 · Method of fabrication anisotropic crystal film on a receptor plate via transfer from the donor plate, the donor plate and the method of fabrication

Abstract

The invention pertains to the field of fabrication of devices of various purposes, which use anisotropic films: polarizers, retarders, etc., as well as technology of obtaining coatings with anisotropy of electric conductivity, magnetic properties, thermal conduction and other physical properties. The invention includes the method of forming anisotropic crystal film on a receptor plate via transferring it from the donor plate Implementing the disclosed invention preserves the high degree of anisotropy and optical parameters of crystal films after the transfer. Additionally, it is possible to form anisotropic coatings on the surface of any configuration (including curved) and different degree of roughness; also, it is possible to transfer films of various sizes and configurations as well as multilayer coatings containing anisotropic film and form color images.

Dependent claims

A method of forming anisotropic crystal film on a receptor plate via transferring it from the donor plate, comprising:

bringing the receptor plate into contact with the donor plate comprising at least one anisotropic crystal film;
activating at least a part of the entire donor plate comprising the anisotropic crystal film, intended to be transferred, and/or at least a part of the receptor plate wherein;
the degree of activation should be sufficient to provide subsequent transfer of the film upon application of pressure, but not sufficient to disrupt crystalline structure of the transferring crystal film;
simultaneous or subsequent to activation application of pressure at least on the part of the entire donor plate comprising the crystal film to be transferred onto the receptor plate wherein;
and
the level of the pressure should be sufficient for the transfer of at least a part of the film from the donor plate to the receptor plate and not sufficient to disrupt crystalline structure of the transferring crystal film.
