Anodic Aluminum Oxidation (AAO) process is widely used as a template or a mold mask of potential applications such as carbon nano tube (CNT), nano rod and nano dots. Different from conventional patterning methods such as e-beam, FIB and photolithograph, AAO has been known that it is possible to fabricate highly ordered nano-patterns on large area. In this study, we introduce a novel anodizing method, which is used low temperature and high voltage. Using LTHV anodizing method, we can obtain a porous alumina membrane with various inter-pore distance and pore diameter. In order to evaluate our porous alumina membrane, various nano-patterns were replicated by using embossing system with various experimental conditions such as pressure, temperature and processing time. Finally, nano pillar arrays can be successfully obtained on PMMA.

In the study, we have developed a straightening system for the SUS 304 micro wires that are normally used in the medical and semi-conductor fields. To apply heat to the micro wires, we introduced the direct wire heating method which generates the thermal energy by the electrical resistance of the wire itself. To avoid the deterioration of the wire surface by the environment, such as the oxidation or the hydration, the N_(2) gas was filled in the glass pipe in which the straightening process was being performed. A precision tension meter was also attached to control the tension of the wire during the heating and straightening process. In order to control the straightening process, several experimental investigations with varying the tension, the feeding velocity and the temperature (current) was carried out. As a result of experiments, we obtained the optimal processing conditions satisfying the straightness requirement of the micro wires.

We developed a simple and cost-effective method of fabrication 3D micro-nano hybrid patterns. In the conventional fabrication methods of the micro-nano hybrid patterns, micro-patterns are fabricated firstly on a substrate, and then nano-patterns are formed on the micro-patterns using e-beam, hologram and nano-probe lithography. However, this methods were limited only to 2 dimensional patterns. In order to improve this dimensional limitation and process time, femtosecond laser and AAO process were used. Femtosecond laser with ultra-fast pulse speed and low thermal damage can be modified effectively a metal surface into another material. Also, AAO process can be easily fabricated nano patterns on Al surface. In this study, using the femtosecond laser as a tool of surface modification of Al thin film, several miro patterns with an amorphous layer on the Al thin film were fabricated with respect to laser intensity and scanning speed. Sequently, micro-nano hybrid patterns were fabricated by using a simple AAO process. Finally, we verified the validity of micro-nano hybrid patterns through SEM and EDS.

A simple method for the fabrication of porous nano-master for the anti-reflection effect on the transparent substrates is presented. In the conventional fabrication methods for antireflective surface, coating method using materials with low refractive index has usually been used. However, it is required to have a high cost and long processing time for mass production. In this paper, we developed a porous nano-master with anti-reflective surface for the molding stamper of the injection mold, hot embossing and UV imprinting by using the aluminum anodizing process. Through two-step anodizing and etching processes, a porous nano-master with anti-reflective surface was fabricated at the large area. Pattern size Pore diameter and inter-pore distance are about 130nm and 200nm, respectively. In order to replicate anti-reflective structure, hot embossing process was performed by varying the processing parameters such as temperature, pressure and embossing time etc. Finally, antireflective surface can be successfully obtained after etching process to remove selectively silicon layer of AAO master.

In this thesis, an active RC filter using high order inverse chebyshev function is designed and the design method for cascading blocks with low sensitivity and maximum dynamic range is discussed. To have maximum dynamic range, we have proposed the simple algorithm with a pole-zero pairing, the cascading sequence by flatness matrix and optimum gain distribution for a given transfer function. And 2nd order Block is designed with negative feedback to improve the sensitivity problem which had a defect at active RC circuits. Using the suggested method, we have designed the active RC low pass filter of the normalized 7th order inverse chebyshev function, as a results, we have shown that this accord with the given specification.

The bio-micro pin has been usually used for the biochemistry analysis. The manufacturing capability of the micro-pin and the their array with the effective and low-cost way is very important and it gives great economical benefits to developers. The micro-pin is composed of the sample channel for holding the liquid with the fixed volume, the flat tip which determines the printing quality and the pin head for preventing the rotation of the pin in the holder. In this study, we have manufactured newly designed micro-pins by the wire-EDM process with special jigs, and analyzed liquid holding and printing characteristics with respect to the variation of the shape and the tip size of the micro-pin.

In this paper, we present the affection of pore generation with respect to variation of temperature in the anodic aluminum oxidation(AAO) process. In conventional AAO methods for aluminum bulk sheet over 25mm, mild anodizing method with low anodizing voltage at 4oC temperature has usually been used. However, it is required to have a long processing time for mass production. In this paper, we suggested the hard anodizing method by low temperature for aluminum thin film of 1mm. Through various AAO experiments with respect to the variation of temperature, pore diameter and inter-pore(between pore and pore) distance at large area can be determined. In order to analysis the pore generation, FE-SEM was measured. Pore diameter and inter-pore distance are about 200nm and 250nm. Finally, concave nano-structures with various diameters can be successfully obtained after etching process to remove selectively AAO layer.
