Among many material processing related issues for successful scaling down of devices for the next 10 years or so, the advanced gate stack and interconnect technology are two most critical research areas, which need technical innovation. The introduction of new metallic films and appropriate processing technologies are required more than ever. Especially, as the device downscaling continues well into sub 50 nm regime, the paradigm for metal nano film deposition technique research has been shifted to high conformality, low growth temperature, high quality with uniformity at large area wafers. Regarding these, ALD has sparked a lot of interests for a number of reasons. The process is intrinsically atomic in nature, resulting in the controlled deposition of films in sub-monolayer units with excellent conformality. In this paper, the overview on the current issues and the future trends in device processing technologies related to metal nano films as well as the R&D trends in these applications will be discussed. The focus will be on the applications for metal gate, capacitor electrode for DRAM, and diffusion barriers/seed layers for Cu interconnect technology.

This article presents a method that improve the drive-license test system, especially the course-driving by using the image processing. Decision(pass or not) is recorded and informed to test-driver after the image processing such as image capture, grayscaling, normalization, Hough transform and decision. That result system enables us to manage much more economically and effectively.

For the Gas hydrate Research and Development in Korea, the prospect area I & II was surveyed and drilled during the first phase. At the result, we succeeded to discovering gas hydrate real sample at BSR reflection and vent structure. This expedition processing contributes to developing the offshore seismic survey technologies and data processing of Korea. But Korean gas hydrate test production research, in spite of activating test production at other countries, is such a limitation about technician, GH production technologies and E&P processing. First of all, there is no exist in Korea to application site for the their production research results. In this paper, we have studied the gas hydrate reservoir selection technics of the DOE & BPXA for the ANS test production. And this result will helpful to preparation of gas hydrate test production in Korea.

We introduce a technical approach for reducing three-dimensional infrared (IR) spectroscopic data generated by integral field spectroscopy or slit-scanning observations. The first part of data reduction using IRAF presents a guideline for processing spectral images from long-slit IR spectroscopy. Multichannel image reconstruction, Image Analysis and Display (MIRIAD) is used in the later part to construct and analyze the data cubes which contain spatial and kinematic information of the objects. This technic has been applied to a sample data set of diffuse 2.1218 ${\mu}m$ $H_2$ 1-0 S(1) emission features observed by slit-scanning around Sgr A East in the Galactic center. Details of image processing for the high-dispersion infrared data are described to suggest a sequence of contamination cleaning and distortion correction. Practical solutions for handling data cubes are presented for survey observations with various configurations of slit positioning.

This study was to determine the technical feasibility of using wastepaper fibers, obtained through dry processing of wastepaper, as reinforcement in thin cement produces. Dry-processed waste papers have high levels of noncellulosic impurities, and the recycling process also breads and damages the fibers. To produce wastepaper fiber-cement composites, first the influential variables in the slurry-dewatering method of processing the composites were identified in an experimental study based on factorial design. Among the proportioning and processing variables investigated, fiber mass fraction and level of substitution of virgin fibers with recycled ones were found to have statistically significant effects on mechanical and physical properties of composites. Subsequently, response surface analysis techniques were used to devise an experimental program that helped determine the optimum combinations of the selected influential variables based on mechanical and physical properties, and cost.

In this paper, a particular application of digital photos, remote sensing, remote shooting air moving, high-resolution and high compression of medical images required by remote shooting of JPEG2000 standard applied in the field of hardware design, production was implemented. JPEG2000 standard for image compression using the software implementation of the processing speed is very slow compared to conventional JPEG disadvantages, and also the standard of JPEG2000 DWT (Discrete wavelet transform) to improve the level of compression for image data if processing speed is a phenomenon that has degraded. In order to solve these JPEG2000 compression / decompression groups were designed and applied. In this paper, the optimal JPEG2000 compression / reservoir hardware by changing the level for still image compression, faster computation speed and quality has shown improvement.

In this paper We propose one computer interface device for handicapped people. Input signals of the interface device are movements of eyeballs and head of handicapped. The movements of the eyeballs and head are detected by an image processing system. One feature of our system is that the operator is not obliged to wear any burdensome device like glasses and a helmet. The sensing performance of the image processing of the eyeballs and head is evaluated through experiments. Experimental results reveal the applicability of our system.

Due to the advances of the Internet technologies and web-based applications, the demand for wide distributed processing is increased. Mobile Agents have been proposed as a model to meet with the requirement for such environment. But current mobile agent system has the technical restriction. The requirement of mobile agent for the wide distributed processing is analysed in mobile agent system architecture, programming paradigm and technologies.

This paper suggests a model of a visual information system for factory automation. The model is composed of a visual processing system with client-server model and RPC(Remote Procedure Calling); a main server for controlling the whole factory automation process; and a processing server which processes the visual information only. To verify its efficiency, the suggested model is realized on the bill recognition system.

Edge detection considers the important technical details of digital image processing. Many edge detection operators already perform edge detection in digital color imaging. In this study, the edge of many real color images that represent the type of digital image was detected using a new operator in the least square approximation method, which is a type of numerical method. The Linear Fitting algorithm is computationally more expensive compared to the Canny, LoG, Sobel, Prewitt, HIS, Fuzzy, Parametric, Synthetic and Vector methods, and Robert' operators. The results showed that the new method can detect an edge in a digital color image with high efficiency compared to standard methods used for edge detection. In addition, the suggested operator is very useful for detecting the edge in a digital color image.
