PECVD법으로 증착된 전자소자용 thiophene 박막의 전기화학적 신뢰성에 관한 연구
김정구,박진택,최윤석,부진효,유용재 대한금속재료학회 2003 대한금속·재료학회지 Vol.41 No.6
The corrosion failure of electronic devices has been a major reliability concern lately. This failure is an ongoing concern because of miniaturization of integrated circuits(IC) and the increased use of polymers in electronic packaging. In this paper plasma-polymerized thiophene films were considered as a possible candidate for an interlayer dielectric for multilever metallization of ultra large scale integrated (ULSI) semiconductor devices. The protective ability of above films as a function RF power in an 3.5 wt.% NaCl solution was examined by electrochemical methods and contact angle measurement. The protective efficiency of the film increased with increasing RF power, which induced the higher degree of cross-linking and hydrophobicity of the films.
PROCAST를 이용한 DC 주조 조건의 미세 조직에 미치는 영향분석

For DC(Direct Chill) casting, the effect of casting conditions such as casting speed, amount of cooling water, melt height in mold, pouring temperature, on microstructure of ingot was investigated. The analysis was performed with casting program PROCAST. Fractional experimental design using OA(Orthogonal Array) was established instead of time-consuming full factorial experimental design. To quantify the measure of microstructure of ingot, DAS(Dendrite Ann Spacing) was used. Therefore, ANOVA(Analysis of Variance) was performed to analyze the effect of casting conditions on microstructure and the optimal casting condition was found.

저자들은 최근 당뇨 및 당뇨성 방광증을 가진 61세 여자 환자에서 발생한 기종성 방광염을 경험 하였기에 문헌 고찰과 함께 보고하는 바이다. Emphysematous cystitis is a rare clinical entity. Persons with diabetics, neurogenic bladder and chronic urinary infection are predisposed to the disease. Severity of illness ranges from an asymptomatic condition to life-threatening cystitis. Treatments consist of establishing bladder drainage and administering proper antibiotics. We report a case of emphysematous cystitis in 61 year old female patient with diabetes melitus.
