CEPA(Comprehensive Economic Partnership Agreement, hereinafter CEPA) between India and Korea may influence some changes on Korean pharmaceutical industry which shows less competitive advantages than Indian industry in many regards. So the purpose of this paper remains on suggesting the way of enhancing international competitiveness for Korean industry on the basis of double diamond model. Through the comprehensive and deep analysis, our findings on recommendable business strategies for Korea are as follows ; in terms of factor conditions, first, cooperative strategy in R&D for developing generics will be required. Second, Introduction of CMO business can be considered. In terms of demand condition, Korean firms should find out the chance for demand creation in Indian market which has future market potential and American market exploration, as soon as possible. With regards to strategy, structure and competition, trying M&A with leading Indian companies and utilizing well organized medical professionals in India will be considered. In the points of related and supportive parts, lastly, Korean government should try to make so called "National Strategic R&D committee" for pharmaceuticals and bring u-healthcare service to Korea in the first place. If Korean pharmaceutical industry implement above-mentioned strategies, CEPA can be turned into business opportunities from the crisis. As a result, Korean firms shall have more powerful global competitiveness eventually.

In this paper, we propose the design on LNA and Down-mixer for MB-OFDM UWB using $0.18\;{\mu}m$ CMOS. LNA, Down-mixer design result shows that it covers the frequency range ken 3 GHz to 5 GHz. The LNA gain is larger than 12.8 dB, and noise figure about 2.6 dB. Double balanced differential down-mixer is designed less than 2 dB gainflatness, and it has over 30 dB LO leakage, feedthrough characteristics.

A 16-bit adiabatic low-power Microprocessor is designed. The processor consists of control block, multi-port register file, program counter, and ALU. An efficient four-phase clock generator is also designed to provide power clocks for adiabatic processor. Adiabatic circuits based on efficient charge recovery logic(ECRL), are designed 0.35,${\mu}{\textrm}{m}$ CMOS technology. Conventional CMOS processor is also designed to compare the energy consumption of microprocessors. Simulation results show that the power consumption of the adiabatic microprocessor is reduced by a factor of 2.9∼3.1 compared to that of conventional CMOS microprocessor.

This paper presents a CMOS TIQ flash A/D converter which operates very fast compared to other types of A/D converters due to its parallel architecture. The output resolution of designed A/D converter is 6-bit. In order to reduce the power consumption and chip area of conventional flash A/D converter, TIQ based flash A/D converter is proposed, which uses the advantage of the structure of CMOS transistors. The length and width of transistors of TIQ were determined with HSPICE simulation. To speed up the ultra-high speed flash A/D converter, the Fat Tree Encoder technique is used. The TIQ A/D converter was designed with full custom method. The chip's maximum power consumption was 38.45mW at 1.8V, and the operating speed of simulation was 2.7 GSPS.

본 논문은 802.11a 무선 랜용 5.25-GHz BiCMOS 저 잡음 증폭기를 제안한다. 이러한 회로는 1볼트 전원에서 동작하며, 저 전압 전원 공급에서도 높은 전압 이득을 가지도록 설계하였다. 제안한 회로는 $0.18{\mu}m$ SiGe HBT BiCMOS로 설계되어 있다. 저 전압 및 저 전력 동작을 위해 바이어스 회로는 밴드 갭 참조 (band-gap reference circuit) 바이어스 회로를 사용하였다. 제안한 회로는 최근 발표된 연구결과에 비해 높은 전압이득, 낮은 잡음지수 및 작은 칩 크기 특성을 보였다.

This paper deals with a detailed analysis of CMOS latch up dependancies on the layout and geo-metrical demensions on the mask using same materials and same processes. For this purpose, six different layout models depending upon the N+ / P+ spacing and three different guard ring models have been gesigned, fabricated, and tested. As a result, common emitter current gain, shunt resistance, and holeing current versus N+/P+ spacing have been measured and analyzed experimentally. Also the fact that guard ring is sffective in reducing the latchup possibility has been verified through this study.

In this paper, novel methods for improvement of thermal stability of Ni-germano Silicide were proposed for nano CMOS applications. It was shown that there happened agglomeration and abnormal oxidation in case of Ni-germano Silicide using Ni only structure. Therefore, 4 kinds of tri-layer structure, such as, Ti/Ni/TiN, Ni/Ti/TiN, Co/Ni/TiN and Ni/Co/TiN were proposed utilizing Co and Ti interlayer to improve thermal stability of Ni-germano Silicide. Ti/Ni/TiN structure showed the best improvement of thermal stability and suppression of abnormal oxidation although all kinds of structures showed improvement of sheet resistance. That is, Ti/Ni/TiN structure showed only 11 ohm/sq. in spite of 600 $^{\circ}C$, 30 min post silicidation annealing while Ni-only structure show 42 ohm/sq. Therefore, Ti/Ni/TiN structure is highly promising for nano-scale CMOS technology.

CMOS 축소화가 32nm node를 넘어서 지속적으로 진행되기 위하여 FinFET, Surround Gate and Tri-Gate와 같은 Fully Depleted 3-Dimensional 소자들이 SCE를 다루기 위해서 많이 제안되어 왔다. 하지만 소자의 축소화를 진행함에 있어서 좁고 균일한 patterning을 형성하는 것과 동시에 낮은 Extension Region과 Contact Region에서의 Series Resistance을 제공하여야 하고 Source/Drain Contact Formation을 확보하여야 한다. 그리고 소자의 축소화가 진행됨으로써 Silicide의 응집현상과 Source/Drain Junction의 누설전류에 대한 허용범위가 점점 엄격해지고 있다. ITRS 2005에 따르면 32nm CMOS에서는 Contact Resistivity가 대략 $2{\times}10-8{\Omega}cm2$이 요구되고 있다. 또한 Three Dimensional 소자에서는 Fin Corner Effect가 Channel Region뿐만 아니라 S/D Region에서도 중대한 영향을 미치게 된다. 따라서 본 논문에서 제시하는 Novel S/D Contact Formation 기술을 이용하여 Self-Aligned Dual/Single Metal Contact을 이루어Patterning에 대한 문제점 해결과 축소화에 따라 증가하는 Contact Resistivity 문제점을 해결책을 제시하고자 한다. 이를 검증하기3D MOSFET제작하고 본 기술을 적용하고 검증한다. 또한 Normal Doping 구조를 가진3D MOSFET뿐만 아니라 SCE를 해결하기 위해서 대안으로 제시되고 있는 SB-MOSFET을 3D 구조로 제작하고, 이 기술을 적용하여 검증한다. 그리고 Silvaco simulation tool을 이용하여 S/D에 Metal이 Contact을 이루는 구조가 Double type과 Triple type에 따라 Contact Resistivity에 미치는 영향을 미리 확인하였고 이를 실험으로 검증하여 소자의 축소화에 따라 대두되는 문제점들의 해결책을 제시하고자 한다.

Background: The purpose of this exploratory study is to explain where, when and how the introduction of user fee system works in low and middle income countries using context, mechanism, and outcome configuration. Methods: Considering advanced research in realist review approach, we made a review process including those following 4 steps. They are identifying the review question, initial theory and mechanism, searching and selecting primary studies, and extracting, analyzing, and synthesizing relevant data. Results: User fee had a detrimental effect on medical utilization in low and middle income countries. Also previous and current interventions and community participation were critical context in user fee system. Those contexts were associated with intervention initiation and recognition and coping strategies. Such contexts and mechanisms were critical explanatory factors in medical utilization. Conclusion: User fee is a series of interventions that are fragile and dynamic. So the introduction of user fee system needs a comprehensive understanding of previous and new intervention, policy infrastructure, and other factors that can influence on medical utilization.
