Abstract
The miniature anti-fake metal sheet with miniature text is produced through first making metal film on the substrate by means of filming technology, then making miniature text and figure pattern on the metal film by means of microlithography, and stripping the metal film from the substrate. The micro characters on the micro anti-counterfeiting metal sheet can be Chinese characters, numbers, English or other foreign languages, and can also be used for manufacturing micro patterns. The shape of the miniature anti-counterfeiting metal sheet is generally rectangular, and the miniature anti-counterfeiting metal sheet can also be made into various shapes such as round, diamond, petal shape and the like. The micro anti-counterfeiting metal sheet has small overall dimension which can be as small as dozens of micrometers, and the micro characters on the sheet have smaller dimension and need to be observed by a high-power magnifying lens. The invention provides a microform character anti-counterfeiting product with a novel and unique structure.
Description
Technical field
The present invention relates to a kind of minitype false proof sheet metal that contains microfilm of characters and have the profile pattern.
Background technology
Microfilm of characters has obtained practical application as a kind of false proof measure.Its main manufacturing technology has printing and mold pressing.As the microfilm of characters on new edition the 5th cover Renminbi is to adopt printing technology that microfilm of characters is produced on the banknote paper, and the microfilm of characters on a lot of antiforge laser holographic trade mark is to adopt mould pressing technology that microfilm of characters is produced on the plastic sheeting.
Goal of the invention
Technology of the present invention is dealt with problems and is: provide a kind of unlike the prior art, adopt microlithography technology that microfilm of characters is produced on minitype false proof sheet metal on the sheet metal.
Technical solution of the present invention is: the minitype false proof sheet metal that contains microfilm of characters, its characteristics are: at first adopt coating technique to make metallic film on substrate, adopt microlithography technology on metallic film, to make microfilm of characters and profile pattern then, and metallic film stripped down from substrate, become the minitype false proof sheet metal that contains microfilm of characters and have the profile pattern.
The preparation of described metallic film mainly may further comprise the steps:
(1) substrate is prepared: the glass sheet of generally selecting surfacing for use is as substrate;
(2) plated film: with vacuum coating equipment plating rete on substrate, as chromium film, aluminium film etc.;
(3) even glue: on metallic diaphragm, evenly apply the photoresist that one deck is used for photoetching with sol evenning machine.
The making of microfilm of characters and profile pattern mainly may further comprise the steps on the described metallic film:
(1) mask plate-making: microfilm of characters and the micro chip profile pattern that designs is made into mask with platemaking equipment and technology;
(2) exposure: the photoresist rete on the metallic diaphragm of making by the step of claim 2 is exposed with exposure sources and technology utilization aforementioned mask version;
(3) develop: with developer solution the photoresist after exposing is developed, on photoresist, form microfilm of characters and profile pattern;
(4) corrosion: the metal film after developing is corroded with corrosive liquid, erode the metal film that exposure place is exposed after developing, and unexposed place protects following metal film not to be corroded because photoresist still exists, thereby forms microfilm of characters and profile pattern on metallic diaphragm;
(5) remove photoresist: spend glue and remove all residual photoresists on the metallic diaphragm, expose the whole metallic diaphragms that contain microfilm of characters and profile pattern;
(6) peel off: with stripper metallic diaphragm is stripped down from substrate, become the metal platelet that contains microfilm of characters and have the profile pattern.
The present invention's advantage compared with prior art is: the microfilm of characters anti-fake product that a kind of novel structure uniqueness is provided.Microfilm of characters can be Chinese character, numeral, English or other foreign language, also can make miniature pattern.The profile pattern of micro chip generally is a rectangle, also can be circular, rhombus, the petal different shape that waits.The present invention makes the precision height, and the physical dimension of the metal platelet of making is very little, may diminish to tens microns, and the microfilm of characters size on the micro chip is littler, observe with high magnified glass.Its making apparatus costliness, complex manufacturing technology, antifalse effect is reliable.
Description of drawings
The lay-by material structural representation that Fig. 1 obtains by the material preparation step for the present invention;
Fig. 2 is the main process flow diagram of microlithography processes of the present invention;
Fig. 3 is the synoptic diagram of the minitype false proof sheet metal of the present invention's making.
Embodiment
Realization of the present invention at first is to plate the layer of metal rete by coating process on substrate, evenly applies one deck photoresist again on metallic diaphragm, makes lay-by material.The structure of lay-by material as shown in Figure 1,1 is glass substrate among the figure, 2 is metallic diaphragm, 3 is photoresist layer.Pass through microlithography processes as shown in Figure 2 then, microfilm of characters and profile pattern are produced on the metallic diaphragm, form the minitype false proof sheet metal.Fig. 3 is that profile is the synoptic diagram of the minitype false proof sheet metal that contains microfilm of characters of rectangle.
One embodiment of the present of invention are that microfilm of characters is produced on the diaphragm of crome metal: at first use coating process, be coated with the chromium rete on glass substrate, evenly apply photoresist layer then on the chromium rete.Utilize microlithography processes again, at first make mask, with four groups of microfilm of characters: " Beijing2008 ", " Chengdu photoelectricity ", " Renminbi ", " CHINESE " and their profile rectangular patterns are produced on the mask, the miniature chromium sheet of four kinds of rectangles that technology is had microfilm of characters " Beijing2008 ", " Chengdu photoelectricity ", " Renminbi ", " CHINESE " respectively such as remove photoresist, peel off through as shown in Figure 2 exposure, development, burn into again.Their physical dimension is respectively: 255 microns * 85 microns, 240 microns * 85 microns, 180 microns * 85 microns, 195 microns * 70 microns.
The minitype false proof sheet metal that contains microfilm of characters that the present invention makes can be used for the false proof of various certificates, card, all kinds of commodity and parts, has application fields and application prospect.
