ABSTRACT:
An ion printer is proposed for simultaneous generation on the spatially fixed substrate of the whole image composed of micron and submicron size elements, containing a fixed substrate with layer of material capable of changing its properties under the ion influence; an ion source with a tool for beam forming, which ensures the divergence angle less than 20°, and with the first tool of acceleration of ions providing them the energy less than the one needed for variation of the properties of the material on the substrate surface. The said ion printer contains also a mask with parallel flat surfaces and with a ratio of its thickness to the distance from the mask to the substrate equals to 1:(0.6–3), correspondingly. The said mask has a plurality of apertures for passing the said accelerated ions, each of the apertures having the ratio of its depth to its cross-section size in the range from 9 to 50. Each of plurality of apertures contains a pair of the first electrode and the second electrode, acting as a tool of regulation of the passing of said ions to the substrate. Said ion printer has also a second tool of acceleration of said ions placed under the said substrate; an electric voltage source connected to each first electrode and to each second electrode; a plurality of controlled switchboards, each electrically connected to the said voltage source and placed between the said voltage source and each of the said second electrode for selective regulation of electric voltage in each aperture and, correspondingly, for the controlled passing of ions in each aperture to the said substrate.
