The development of large-area, high-resolution nano-patterning with high-aspect-ratios is a challenging problem that must be solved for potential applications in high performance nanoscale devices. To date, soft-, e-beam and soft-building block-lithography have been primarily used in such applications. Here, we describe two new patterning techniques that enables fabrication of ultra high-resolution and high-aspect-ratio patterns of various shapes. First, we introduce an advanced ultrahigh-resolution (~10 nm) patterning technique that enables the fabrication of various high aspect ratio of nanostructures. This method provides many strategies to fabricate complex continuous patterns and multi-component patterns with 10 nm-scale. We also introduce a new bottom-down lithography, named dendrimer lithography, where significant progress has been made to generate single domain of supramolecular columnar structure with smaller diameters (~< 5 nm), higher area densities in the template.

본 논문에서는 에지 검출을 이용한 물체 추적 시스템을 제안한다. 시스템은 RC 카메라와 상하좌우 움직이는 모터로 구성되어 있다. 움직이는 물체가 감지되면 에지 검출을 하여 마이크로컨트롤러가 모터를 구동하게 된다. 제안한 자동물체 추적 시스템은 다른 무인 감시 시스템보다 쉽게 물체를 감시하고 제어하는데 이용할 수 있다. In this paper, we presents a auto target tracking system based on edge detection. This system consists of a PC camera and pan-tilt motors. The motors are drived by auto edge detection commands based on a microcontroller which is identified a moving target object. Our a auto target tracking system can be readily applied to monitor and control other unmanned watch system.

Single-walled carbon nanotubes (SWNTs) are interesting molecular wires with unique electronic properties that have been spotlighted for future solid-state nanoelectronics. We developed the fabrication process for the formation of the patterned SWNTs film. Unrestricted patterning of SWNTs films were employed lithography technology. The resultant versatile carbon nanotube film will be suitable for use in micro- or nanoscale electronic devices and circuits.
