Description of the Invention: [Technical Field] [0001] The present invention relates to a resist and a nanoimprint method using the same, and more particularly to a nanoimprint resist and using the same A nanoimprint method for embossing resists. [Prior Art] [In the prior art] In the prior art, when manufacturing various semiconductor devices, it is often required to produce a nano pattern having a fine structure of several tens of nanometers to several hundreds of nanometers. A nano-pattern having the above-described fine structure is mainly produced by photolithography or electron beam lithography: first, using a mask or scanning focused radiation or electron beam 'radiation photo-resistance composition or mask The radiation or electron beam described above will change the chemical structure of the resist in the exposed region; then, the exposed region or the resist outside the exposed region is removed by etching to obtain a specific pattern. [0003] In order to adapt to the rapid development of integrated circuit technology, while the first optical lithography strives to break through the resolution limit, the next generation lithography technology has gained a lot of research in recent years. Previous novel lithography systems, including reflective optical systems and refractive optical systems, have been used to reduce the intense light absorption in refractive systems by using extreme ultraviolet lithography using a source of wavelengths from 13 to 14 nm and a highly accurate reflective optical system. However, the entire lithography system is very expensive and limits the application of this technology. [0004] Since the 1990s, a new nano-patterning process has been developed (see Chou SY, Krauss PR, Renst_ P. Imprint of sub 25 nm vias and trenches in polymers. Appl. Phys. Lett ., 1995, 67(21). 098120562 Form No. A〇l〇i Page 3 of 27 Page 0992035022-0 201100457 3114-3116). The above-mentioned new technology for making nanographs is known in the art as nanoimprint or nanoimprint lithography. Nano-embossing refers to the use of a template with a nano-pattern to imprint a resist film on a substrate, and then process the nano-pattern on the substrate, such as etching, stripping, etc. A pattern and a semiconductor device having a nanostructure are fabricated. A method of forming a nano pattern by a nanoimprint technique by forming a nano pattern by using a hard template imprint resist layer having a nano pattern without relying on any exposure formation. Therefore, nanoimprint technology can eliminate the secret conditions necessary in conventional photolithographic methods, such as the limitation of the wavelength of light, and the reverse political and optical interference of particles in the resist and substrate. Therefore, compared with lithography, nanoimprint technology has the advantages of low production cost, simplicity, and efficiency, and has broad application prospects. [0005] The first-hand Nexe imprinting technology mainly includes hot nanoimprint (HEm), ultraviolet nanoimprint (UV-NIL) and the like. The thermal embossing system uses a rigid template painted with a nano pattern to imprint the anti-caries film on the heated substrate to a nano-scale pattern, and then cure the anti-surname agent by cooling to imprint After the nai (four) case can be saved, and finally, the use of conventional engraving, stripping and other methods of reinforcement to achieve the Nai (four) case to the base of the transfer. The template is usually made of inert materials such as high hardness, high thermal conductivity, low thermal expansion coefficient and strong anti-corrosion properties, such as _, dioxotomy and carbonized H-cut. The substrate is a common (four) piece of 'diazepine slab, or a stone slab of money with a metal base film. The process of hot nanoimprinting is complicated and the conditions are strict. _6] UV Nylon printing system to produce the rigid template of the Nai (4) case, the base 098120562 Form No. A0101 Page 4 / 27 pages 0982035022- 201100457 On-chip liquid resist thin embossed nano-scale pattern Then, the resist monomer polymer is cured by ultraviolet light irradiation, the nano-scale pattern is preserved, and finally, the nano pattern is transferred from the template to the substrate by a conventional etching, peeling, or the like. Compared with the thermal nanoimprint, the UV nanoimprint resist has good fluidity at normal temperature, and it is not necessary to obtain a nano-scale pattern under high temperature and high temperature conditions, and the method cost Lower. In the prior art, the ultraviolet nanoimprint resists mainly include a ruthenium rubber series 'epoxy series' acryl vinegar series and a polystyrene series. G [0007] 〇 [0008] [0009] [0010] 098120562 However, the prior art UV nanoimprint resist has low mechanical stability, strong adhesion to the template, and slow curing speed. In order to improve the resolution of the nano-pattern, it is often necessary to demolish the template by demolding, obtaining the nano pattern (4), and having a lower resolution of 1 and using the previous nanoimprint resist UV-imprinting method. Pretreatment, such as treatment of the template with acid. The pretreatment process of such a template is complicated, which increases the process complexity and cost of the UV nanoimprint. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a nanoimprint method in which a curing speed is fast, a mechanical stability is good, and a nano-pressure anti-reagent is used. - Nanoimprinting resistance _'The nanoimprinting resistance _ includes the following components. : Highly branched oligomers, perfluoropolyethyl _, f-based acrylic acid methyl vinegar, free radical initiators and organic Thinner.

[0043] Again, the nanoimprint resist of the imprinted resist layer 130 is cured by ultraviolet light, and a nano pattern is formed on the imprinted resist layer 130. The nanoimprint resist of the imprint resist layer 130 is cured by ultraviolet light, and demolded, thereby obtaining a cured nano pattern. The template 20 is separated from the substrate 10 such that a nano pattern of the surface of the template 20 is copied to the imprinted resist layer 130. The nano pattern formed by the embossed resist layer 130 includes a plurality of second recesses 16 and second protrusions 14. And the second groove 16 corresponds to the first protrusion 24, and the second protrusion 14 corresponds to the first groove 26.

The specific steps of the wet etching are: taking an appropriate amount of chromium etching solution K3 [Fe(CN,], which is 摩尔·〇6 mol/liter to 0.25 mol/liter, and placing the substrate 1〇 into the chromium etching solution, Immersion for 4 minutes to 15 minutes. The second sacrificial layer 120 at the bottom of the second recess 16 is covered by the nanoimprint resist, and under the impregnation of the chromium corrosive liquid, the bottom of the second recess 16 The second sacrificial layer 120 is removed to expose the first sacrificial layer 11 (). In this embodiment, when the second sacrificial layer 12 () material is aluminum, dry etching is used; When the material of the sacrificial layer 120 is chromium, the dry method is used to engrave the surname or the wet method. Again, the first sacrificial layer 11〇 at the bottom of the second recess 16 is removed to expose the substrate 10. 'Oxygen plasma can be used to remove the second The first sacrificial layer 11{) at the bottom of the recess 16 exposes the substrate 10.

Finally, the substrate 1 底部 at the bottom of the second recess 16 is etched, and the residual organic material is removed with an organic solvent to obtain a substrate having a nano pattern. [0058] 098120562 Specifically, the substrate 10 is placed thereon. In an inductively coupled plasma system, the substrate 10 at the bottom of the second recess 16 is not protected by the first sacrificial layer 11〇: the second recess 16 of the substrate is numbered with four gasified helium and gas as an etching gas. A0101 Page 14 of 27 0982035022-0 201100457 [0059] 006 [0062] The portion of the substrate at the bottom of the second groove 16 will be removed; the residual organic residue is washed away with acetone The first sacrificial layer 110 is organic, so that the second sacrificial layer 120 overlying the first sacrificial layer 110 is also removed, thereby obtaining a substrate 1 having a nano pattern.

The substrate 10 at the bottom of the second recess 16 is etched. It can be understood that in the nanoimprint method of the embodiment, the first sacrificial layer 110 and the second sacrificial layer 120 may not be formed. An imprint resist layer 130 is formed directly on the surface of the substrate 10 to carry out the nanoimprint method described in this embodiment.
