Abstract

A method of creating microstructures by contact transfer process includes the step of positioning a material covered ribbon in proximity with the surface of the substrate, directing a laser beam onto the material covered ribbon, so that the laser beam releases a portion of the material layer and transfers the released material onto the surface of the substrate. The material covered ribbon includes a transparent support and a material layer of the thickness in the range of 2-15 microns of highly homogeneous and uniformly distributed material, which includes a powder of very small particles the dimensions of which do not exceed 10 microns bound by a binder which provides a needed degree of viscosity to the material, which, being released from the material layer, is transferred to the surface of the substrate as a single piece. In order to create a microstructure, several repetitions of releasing the material and transferring the released material to the substrate is needed. Very fine features with no edge irregularities are created by this method.
