(1) Micro-contact printing technology (MCP) That is, the organic polymer solution is used as an ink, applied to the image part of the silicone rubber plate, and the organic polymer at the protrusion of the plate is transferred to the surface of the printed substrate through the method of micro-contact printing (Figure 6). Due to the inventor's ingenious design, the organic polymer is firmly attracted to the surface of the substrate, forming a concave-convex image of molecular thickness. People call this technology micro-contact printing technology. It should be noted here that in the early experiments, the organic polymer ethanol solution with mercapto groups was used as the ink. The so-called substrate refers to a silicon sheet coated with a gold film on the surface. When people transfer the polymer solution containing mercapto groups on the silicone rubber plate to the gold film, a self-assembled monomolecular film image is formed. Mizutani and others from the Nanotechnology Research Department of the Japan Institute of Industrial Technology pointed out that in addition to organic polymer solutions containing sulfhydryl groups can be used as inks for microcontact printing, scientists have recently discovered aminosilanes with chemically active surfaces. It is also a very good performance ink. The image printed with this ink (the substrate is a mica plate) was confirmed by atomic energy microscope (AFM) detection, and a large number of DNA molecules were adsorbed on the surface of the aminosilane image. It is believed that this is because the positive charge on the surface of the aminosilane and the negatively charged DNA molecules attract each other. Micro-contact printing not only has the advantages of fast and cheap, but also does not require the harsh conditions of the clean room, or even an absolutely flat surface. Micro-contact printing is also suitable for a variety of different surfaces, with flexible and variable operating methods. The disadvantage of this method is that at the submicron scale, the diffusion of thiol molecules during printing will affect the contrast and make the printed pattern wider. By optimizing the immersion method and immersion time, especially controlling the amount and distribution of ink on the stamper, the diffusion effect can be reduced. (2) Capillary Microstyling (MIMIC) That is, the printing plate with the nano-concave image is placed on the surface of the substrate. At this time, the unevenness of the image of the printing plate forms a very thin gap (capillary) with the surface of the substrate, and then the liquid polymer is dropped on the silicone rubber plate. Due to capillary action, the liquid polymer enters these gaps by itself. If we cure the polymer in the gap and separate the two, we can obtain a fine nano-concave image. This technology can be widely used in the manufacturing field of optical components and the like. (3) Micro-transfer styling (mTM) That is, the prepolymer is used as an ink, applied to the depression of the silicone rubber plate, and the prepolymer is transferred to the surface of the substrate by transfer, and then heated and cured to form a nano-concave image. We call this printing method micro-transfer styling. (4) Near-field phase conversion printing (PSL) That is, after the photoresist coating is coated on the substrate, the image is transferred on the resist coating film with a silicone rubber mold, and it is used as a mask for contact exposure, such as contact exposure with ultraviolet light. Since the uneven pattern transferred by the silicone rubber mold induces phase conversion, it is possible to form an image. However, the prerequisite is that the size of the concave and convex parts of the image is smaller than the wavelength of the ultraviolet light, and the effect of the near-field light can make the image transfer become a reality. Recently, there are reports in the literature that this technique can form nano-images on the spherical surface. In addition to this, there is nanochemical lithography. It is one of the latest types of nanomaterial self-assembly technology. In the demonstration of the scientists, this process can effectively form a very stable periodic array of nanoparticles without previous lithography (such as atomic microscope dip printing, laser lithography, electron beam lithography, rolling) Printing, etc.) are limited by many defects and limitations. Nano-chemical lithography involves the production of nano-sized periodic template technology, which requires absolute control over size, size, spatial distribution and function. Nanochemical lithography is a combination of multiple technologies, in which the arrangement of particles is controlled by reflecting the difference in activity, which is determined by the type of chemical treatment to which the particles and their surfaces are exposed. Scientists use garnet red yttrium aluminum (YAG) nanoparticles polymerized on silicon chips to synthesize additive particles and crystallize them to determine their shape and composition. Before polymerizing the nanoparticles on the silicon chip, scientists used an etching technique based on the "atomic step" phenomenon to engrave the template on the silicon chip in advance. Due to the high pace of atoms that naturally exist on the surface of silicon chips, scientists can move these atoms through processing to create the required template. A thin layer of nitride formed by chemical reaction (between silicon, nitrogen, and oxygen) is correspondingly formed on the boundary of atomic steps, so that the template is pre-engraved on the chip. To align the particles along the template on the chip, the scientists placed the sample in an ultra-high vacuum chamber and annealed it for several hours. After processing at 500-850 degrees Celsius, not only the nanoparticles precisely arranged based on the template are obtained, but also another advantage is obtained. After using this technique to measure the quenching treatment, the arrangement of the nanomaterials can also show its strength. In general, many nanoparticles are exposed to photon bleaching. This damage is caused by exposure to high-intensity light; on the other hand, these particles keep theirs under the extended illumination of scientists ’fluorescence imaging measurement technology. Initial state. All in all, nano image printing is not a traditional printing technology, it is a newly emerging so-called soft printing technology. This technology has broken the limits of today's printing accuracy (micron level) and pushed printing to the nano-processing level. It has become one of the important means of nanostructures, nanodevices, and even nanomachine manufacturing. Nano image printing technology is currently considered to be the closest to practical manufacturing technology, which indicates that profound changes are taking place in the field of fine processing. The manufacture of ultra-fine images with nanostructures will come out of the scientists ’labs and quickly move to the practical stage. There are currently nanoprinting devices on the market in Japan. However, in order to form a good structure, it is also necessary to develop related technologies led by nano-templates and resin materials, and this research is currently being carried out worldwide. The application focus of nano-image printing technology is mainly in the fields of electronics and microelectronics, but it has also begun to involve in the field of edge energy. With the continuous deepening of research on soft printing technology represented by nano image printing technology, it will surely promote a more profound revolution in electronics, microelectronics, printing and other related technologies.
