현재 반도체 산업에서는 디바이스의 고 집적화, 고 수율을 목적으로 패턴의 미세화 및 웨이퍼의 대면적화와 같은 이슈가 크게 부각되고 있다. 다중 패터닝(multiple patterning) 기술을 통하여 고 집적 패턴을 구현이 가능해졌으며, 이와 같은 상황에서 각 패턴의 임계치수(critical dimension) 변화는 패턴의 위치 및 품질에 큰 영향을 끼치기 때문에 포토마스크의 임계치수 균일도(critical dimension uniformity, CDU)가 제작 공정에서 주요 파라미터로 인식되고 있다. 반도체 광 리소그래피 공정에서 크롬(Cr) 박막은 사용되는 포토 마스크의 재료로 널리 사용되고 있으며, 이러한 포토마스크는 fused silica, chrome, PR의 박막 층으로 이루어져 있다. 포토마스크의 패턴은 플라즈마 식각 장비를 이용하여 형성하게 되므로, 식각 공정의 플라즈마 균일도를 계측하고 관리 하는 것은 공정 결과물 관리에 필수적이며 전체 반도체 공정 수율에도 큰 영향을 미친다. 흔히, 포토마스크 임계치수는 플라즈마 공정에서의 라디칼 농도 및 식각 선택비에 의해 크게 영향을 받는 것으로 알려져 왔다. 본 연구에서는 Cr 포토마스크 에칭 공정에서의 Cl2/O2 공정 플라즈마에 대해 O2 가스 주입량에 따른 식각 선택비(etch selectivity) 변화를 계측하여 선택비 제어를 통한 Cr 포토마스크 임계치수 균일도 향상을 실험적으로 입증하였다. 연구에서 사용한 플라즈마 계측 방법인 발광분광법(OES)과 optical actinometry의 적합성을 확인하기 위해서 Cl2 가스 주입량에 따른 actinometer 기체(Ar)에 대한 atomic Cl 농도비를 계측하였고, actinometry 이론에 근거하여 linear regression error 1.9%을 보였다. 다음으로, O2 가스 주입비에 따른 Cr 및 PR의 식각률(etch rate)을 계측함으로써 식각 선택비(etch selectivity)의 변화율이 적은 O2 가스 농도 범위(8-14%)를 확인하였고, 이 구간에서 임계치수 균일도가 가장 좋을 것으로 예상할 수 있었다. (그림 1) 또한, spatially resolvable optical emission spectrometer(SROES)를 사용하여 플라즈마 챔버 내부의 O atom 및 Cl radical의 공간 농도 분포를 확인하였다. 포토마스크의 임계치수 균일도(CDU)는 챔버 내부의 식각 선택비의 변화율에 강하게 영향을 받을 것으로 예상하였고, 이를 입증하기 위해 각각 다른 O2 농도 환경에서 포토마스크 임계치수 값을 확인하였다. (표1) O2 11%에서 측정된 임계치수 균일도는 1.3nm, 그 외의 O2 가스 주입량에 대해서는 임계치수 균일도 ~1.7nm의 범위를 보이며, 이는 25% 임계치수 균일도 향상을 의미함을 보인다.

This study investigated the conceptualization and application of new concept of regional resilience with case study in Korea in order to promote more sustainable regional development strategies, while problematizing dominant regional competitiveness concept in the current regional development circle under the condition of stagnant growth and ever-existing crisis in these days. Through literature review, this paper found out that regional resilience is a useful concept both to understand dramatic regional changes and to promote new regional development strategies. Furthermore, the study formulated basic research topics and issues for regional resilience through reviewing existing research outcomes on the measurement and factors of regional resilience. Through case study of two macro city-regions in Korea, this study also found out that regional resilience patterns and processes are differentiated according to the place and its scale and that both regional industrial structure formed in a path-dependent way and regional competitive characteristics are all significant to understand the regional resilience patterns and processes.

The purpose of this study is to understand the social and cultural implication of the activities of taking 'selfies' and the use of Social Network Service(SNS)s through the personal story of a 20s female researcher. She analyzes her own digital photography activities based on the experience of the use of Cyworld photo albums for three years and the use of pictures in iPhone album for fifteen months. The other researcher(40s male) cooperates to answer the questions about how to understand the digital photography activities. We understand the digital photography activities including digital cameras, social network services and smart phones as acts of personal identity configuration and acts of making the personal documentary. As a result, digital photos are used more for archive purpose rather than for document purpose. Also, we found that the digital photography activities can be understood as the interactions between human and non-human actors in the perspective of Actor-Network Theory (ANT).

This study aimed to identify the entire lifecycle of research projects in science and technology. Specifically, it attempted to reveal major research steps and research activities from the beginning to the end of R&D projects. It also investigated information needs, source use and problems scientists encounter in each research step. In-depth interviews with 24 Korean scientists in the fields of bio- and nano-science and technology revealed five major steps of lifecycle, namely idea formation, seeking funding, experiment and analysis, output disseminations, and evaluation. We further identified specific information behaviors and salient communication and research tools in each step.

Given the recent trend in business markets to seek and conscientiously develop long-term relationships, it has become increasingly important to understand why such long-term relationships are developed and how they are maintained. Despite their obvious importance, the antecedent conditions and processes of long-term relationships between industrial buyers and suppliers have not been systematically studied. In this research, I report a study of the antecedents of industrial buyer-seller relationships and the relational performance. What kinds of factors contribute to the development of long-term relationships\ulcorner How do these factors influence the corporate performance in the business markets\ulcorner The primary motivation of this study was drawn from an interest in answering these research questions. Managerial implications of the study results are also discussed.

Buyers are transforming their relations with suppliers. For examples, Instead of playing off dozens or even hundreds of competing suppliers against each other, many firms are finding it more profitable to work closly with only a small number of ＂partners＂. If will facilitate a move from single-supplier arrangements(＂hierachies＂) to mutiple supplier arrangement(＂markets＂) because it reduces the costs of coordination with suppliers. According to this logic, Technological developments which lower the cost of acquiring information about prices and product characteristics in a given market should increase to the nymber of tends to lower coordination costs, it wide adoption should lead to an increase in the number of suppliers for most firms, other things being equal. An efficient merket is defined a one that reduces the numer of intermediaries, or the number of Intermediary steps necessary of market tracsaction. It is true that one can order some products via mail order, which reduces the number of intermediaries and cuts transaction costs further Similary, the growth of a global commerce nerwork such as the internet may futher reduce the number of intermediary steps necessary for trade.

The purpose of this study is to analyze newspaper articles from corpus linguistic point of view. We used a large corpus of newspaper articles built from <21st century Sejong Project> and counted occurrences of certain expressions. A newspaper article is divided into the headline, the lead and the body. We tried to figure out how to measure the characteristics of indication and compression which are typical to headlines. Then, we focused on the differences between the headline and the lead. finally, we analyzed the sentence structure and measured the ratio of the frequency of common nouns in the body. This study verifies the existing stylistic theories of newspapers and shows new aspects of language use in newspaper articles. Texts like newspaper articles are the results of human language processing and they in turn affect the development of cognitive ability of language.

Formation of optical meaning shown in the picture book screen is the original expression method in that it makes you understand properties or characteristics of subjects more easily and faster adding another images to them, exaggerating or reducing them as well as shows the phenomenon that you try to deliver. In this study, I first prepared the framework of classification on metaphorical expression methods of the picture books' illustration through theoretical study on the optical metaphorical characteristics and expression forms to analyze how the metaphorical expression methods shown in the picture books for children works optically and psychologically to them. Also, I divided the expression form into 2 types to derive optical psychological perceptional response of children through the empirical survey and analyzed linguistic psychological response of children by type utilizing it as the survey materials of in-depth interviews. Finally, I think that the result of this study will help screen production based on personality and creativity of illustrators and, in addition, it will be utilized in studies and tests of the effective expression methods for students who learn illustration.

Knowledge network is considered to be an important factor in securing regional economic performance and competitiveness. In addition, research institutes that are capable of absorbing knowledge tend to form a global knowledge network regardless of geographical factors, and those that are not, are heavily influenced by regional factors. In this study, we examined how much influence of geographical factors of knowledge network is influenced by lower knowledge absorptive capacity in Korea. As a result, it was shown that the higher institutes of knowledge absorption, the more international collaborative research is being carried out. In other words, a region where science and technology has developed means that regional factors are no longer important factors. The results of this study correspond with the discussion of the preceding theories. In addition, it is worthy of study in that the precedent study was carried out in the case study in Korea.
