Abstract:
Nanoimprint lithography has attracted considerable attention in academic and industrial fields as one of the most prominent lithographic techniques for the fabrication of the nanoscale devices. Effectively controllable shapes of fabricated elements, extremely high resolution, and cost-effectiveness of this especial lithographic system have shown unlimited potential to be utilized for practical applications. In the past decade, many different lithographic techniques have been developed such as electron beam lithography, photolithography, and nanoimprint lithography. Among them, nanoimprint lithography has proven to have not only various advantages that other lithographic techniques have but also potential to minimize the limitations of current lithographic techniques. In this review, we summarize current lithography techniques and, furthermore, investigate the nanoimprint lithography in detail in particular focusing on the types of molds. Nanoimprint lithography can be categorized into three different techniques (hard-mold, soft-mold, and hybrid nanoimprint) depending upon the molds for imprint with different advantages and disadvantages. With numerous studies and improvements, nanoimprint lithography has shown great potential which maximizes its effectiveness in patterning by minimizing its limitations. This technique will surely be the next generation lithographic technique which will open the new paradigm for the patterning and fabrication in nanoscale devices in industry.

Abstract:
AbstractNanoimprint lithography is a potentially low-cost, high-resolution patterning technique, but most of the surrounding development work has been directed toward tool designs and processing techniques. There remains a tremendous opportunity and need to develop new materials for specific nanoimprint applications. This article provides an overview of relevant materials-related development work for nanoimprint lithographic applications. Material requirements for nanoimprint patterning for the sub-45-nm integrated-circuit regime are discussed, along with proposed nanoimprint applications such as imprintable dielectrics, conducting polymers, biocompatible materials, and materials for microfluidic devices. Polymers available for thermal nanoimprint processing and photocurable precursors for ultraviolet-assisted nanoimprint lithography are discussed.

Abstract:
Nanoimprint lithography (NIL) has overcome the limitation of light diffraction. It is capable of printing features less than 10nm in size with high lithographic resolution, high manufacturing speed, and low production cost. The uniformity of pressure, however, remains a critical issue. To improve the uniformity of pressure, we developed a flexible uniform pressure component based on Pascal's Law. When external force is applied to this component, uniform pressure is delivered to the mold and substrate. Average pressure over the embossed area using our improved nanoimprint equipment deviates by only 3.15%.

Abstract:
In this paper, we propose a novel kind of UV click-polymerization thiol-ene copolymers as nanoimprint lithography resists for sub-70 nm resolution patterns. High-precision mold imprint and release are two of the most critical steps of nanoimprint lithography, which requires the resists with properties of excellent conformal replication and low surface energy. Conventional UV-curable resists used in nanoimprint lithography, such as acrylate, epoxy resin, and vinyl ether, cannot satisfy all these properties requirements because they exhibit surface oxygen inhibition during polymerization, or materials fracture and delamination during mold releasing. A novel kind of thiol-ene copolymers have been investigated in this study, which have many properties favorable for use as nanoimprint lithography resists to imprint sub-70 nm and high-aspect-ratio nanostructures. These properties include sufficiently low viscosity and high Young's modulus, low surface energy for easy demolding, polymerization in benign ambient, and in particular, high chemical-etch resistance. These excellent properties give improve nanoimprinting results.

Abstract:
Nanoimprint lithography has a great development in decades. Compressional gas cushion press is a novel method in improving the uniformity in nanoimprint lithography process. Based on compressional gas cushion press nanoimprint lithography system, an attenuation ring is added between the chamber wall and the pedestal. The attenuation ring decreases the influence of system vibration on the fidelity of patterning. The physical parameters of the attenuation material are optimized based on the theoretical models of the vibration attenuation and mechanical calculation. According to the optimization physical parameters, Young's modulus of a perfect material of attenuation ring should be smaller than 8 MPa, and Poisson's ratio should be close to 0.5. Therefore, natural rubber is employed as the material of attenuation ring. The simulation results based on COMSOL indicate that nested rectangular structure has the best attenuation effect among the four simulated internal structures. It provides technological supporting for the establishment of attenuation ring in compressional gas cushion press nanoimprint lithography system.

Abstract:
The nanoimprint replication of biomimetic nanostructures can be interesting for a wide range of applications. We demonstrate the process chain for Morpho-blue-inspired nanostructures, which are especially challenging for the nanoimprint process, since they consist of multilayer undercut structures, which typically cannot be replicated using nanoimprint lithography. To achieve this, we used a specially made, proprietary imprint material to firstly allow successful stamp fabrication from an undercut master structure, and secondly to enable UV-based nanoimprinting using the same material. Nanoimprinting was performed on polymer substrates with stamps on polymer backplanes to be compatible with roller-based imprinting processes. We started with single layer undercut structures to finally show that it is possible to successfully replicate a multilayer undercut stamp from a multilayer undercut master and use this stamp to obtain multilayer undercut nanoimprinted samples.

We report on the fabrication and characterization of nanoimprinted photonic crystals in this new functional material. Experiments showed good imprint properties of the NC/polymer based material and that the surface nanostructuration improves the light extraction efficiency by over 2 compared to a nanoimprinted unpatterned surface.

Abstract:
Due to its inherent simplicity and low cost, the popularity of nanoimprint lithography is rising, and is positioned to succeed EUV as the most popular choice for next-generation lithography. This paper presents a homemade nanoimprint lithography prototype tool with a high precision alignment system, which adopts both macro and micro actuators to achieve coarse and fine alignment. Linear motors with 300 mm travel range and 0.1 µm step resolution, and piezoelectric translators with 50 µm travel range and 0.1 nm step resolution are used as macro and micro actuators, respectively. Imprint of 80nm width gratings with a 250 nm pitch is taken as an example to depict the process of NIL. High resolution and fine fidelity of the imprinted results demonstrate NIL’s promising candidate for next-generation lithography, and potential applications in manufacturing integrated circuits, optical, chemical, and biological nanostructures or micro-devices.

Abstract:
Nanoimprint lithography (NIL) technology has aroused great interests in both academia and industry due to its high resolution, low-cost, and high-volume nanopatterning capability. And as an expoxy resin-based negative amplified photoresist, SU-8 is an ideal candidate for NIL because of its low-glass-transition temperature, low-volume shrinkage coefficient, and good optical properties. In this reviewing paper, we highlight the major technical achievements in NIL on epoxy resin and its applications for bio- and nanophotonic structures. NIL was also applied for the duplication of imprint templates, originally fabricated by e-beam lithography (EBL) followed by reactive ion etch (RIE), using a SU-8/ SiO 2/PMMA tri-layer technique. And nanoimprint properties were systematically investigated for optimization. The developed nanoimprint process for different applications indicates promising industrial potentials in the next generation lithography resolution.

Abstract:
In this paper, a method of multistep imprint lithography process is described. Through comparing among the loading process factors, a multistep loading locus, which includes a pre-cure release of the pressing force, is proposed for the high-conformity transfer of nano-patterns from the template to the wafer. A series of imprint experiments show that the new multistep loading process can meet the needs for different pressing areas, feature sizes and repetitious imprints. This loading process can effectively reduce the residual resist thickness while maintaining a uniform residual resist and non-distorted transfer of nano-patterns to the resist-coated wafer. And a high-conformity of 100 nm feature can be achieved.

Abstract:
nanoimprint was developed quickly in decades because of its ultrahigh resolution, low cost, high throughput. It has demonstrated the ability to pattern 5 nm line-width and 12 inch wafer, and is one of the support technology in NGL. This paper reported a novel nanoimprint to improve the pressure uniformity with air cushion press. The chamber is sealed by a SiO2 window with an elastic ring membrane, on which the mold is fixed . Ultraviolet light solidify resist on the wafer through this window. When air in chamber bleeded the window falled and the mold is pressed into the resist. If air leading into the chamber again, the mold separate from substrate by the elastic ring membrane, then the patterns on mold are translated onto the substrate. Experiments exhibit that this nanoimprint system can replicate features with high fidelity over a large patterning area.

Abstract:
Nanoimprint lithography is a promising technology to produce sub-100 nm scale features on silicon chips. One of key issues in the nanoimprint lithography is how to make uniform contact between the stamp and the substrate on a large area. In this study a rubber membrane unit under substrate is introduced to resolve this problem. Two layers of membrane were designed to consider air flow in the middle of resist on a silicon wafer. The geometry design for accomplishing uniform contact was carried out using finite element analysis. The material modeling of hyperelastic properties of rubber is characterized by the Mooney-Rivlin strain energy functions. Material constants in the strain energy functions are able to be determined via the curve fitting of experimental stress-strain data. Simple tension and equi-biaxial tests were performed to determine the material constants. To evaluate the effects of a rubber membrane unit, nanoimprint lithography process with it was executed. We could confirm that a distinct improvement of uniform contact was shown and air flow problem was solved during the process.

Abstract:
Owning to the robust characteristics of diamonds, a nano-tip array structured mold was fabricated with diamond, we can then use this mold to produce anti-reflection (AR) films with nanoimprint lithography. Taking advantage of the self-ordered characteristic of anodic aluminum oxide (AAO), we can obtain the diamond mold by depositing a layer of diamond on the AAO using hot filament chemical vapor deposition (HFCVD). Then taking advantage of the high through-put characteristics of nanoimprint lithography, AR films can be mass produced. The AR films were subjected to reflectivity inspections, a 5.5% reduction in reflectivity was obtained.
