PMOS에 적합한 Mo 전극의 전기적 화학적 안정성

노영진,이충근,홍신남 대한전자공학회 2004 電子工學會論文誌-SD (Semiconductor and devices) Vol.41 No.04

In this paper, the properties of Mo as PMOS gate electrodes were studied. The work-function of Mo extracted from C-V characteristic curves was appropriate for PMOS. To identify the electrical and chemical stability of Mo metal gate, the changes of work-function and EOT(Effective Oxide Thickness) values were investigated after 600, 700, 800 and 900℃ RTA(Rapid Thermal Annealing). Also it was found that Mo metal gate was stable up to 900℃ with underlying SiO2 through X-ray diffraction measurement. Sheet resistances of Mo metal gate obtained from 4-point probe were less than 10 Ω/□ that was much lower than those of polysilicon. 본 논문에서는 Mo을 PMOS의 금속 게이트로 사용하였을 때의 Mo의 특성에 대해서 연구 하였다. Mo을 게이트 물질로 사용한 MOS 커패시터를 제작하였고, 소자의 C-V 특성 곡선으로부터 일함수를 추출하였다. 그 결과 Mo 게이트는 PMOS에 적합한 일함수를 나타내는 것을 알 수 있었다. Mo의 전기적/화학적 안정성을 검증하기 위해서 600, 700, 800 그리고 900℃에서 급속 열처리를 수행하였으며 열처리 이후 유효 산화막의 두께와 일함수의 변화를 살펴보았다. 또한 900℃ 열처리 이후의 XRD 분석을 통해서 Mo 금속 게이트가 SiO2에 대해서 안정하다는 것을 확인하였다. 4점 탐침기로 측정한 Mo 금속 게이트의 면저항은 10 Ω/□ 미만으로 폴리 실리콘에 비해서 매우 작은 값을 나타냈다.

Lymphoepithelioma-like carcinoma exhibits immunohistochemically similar features to lymphoepitheliomaand commonly occurs in the skin, salivary gland, breast, lung, gastrointestinaltract, liver, urinary tract, prostate, vulva and vagina. Lymphoepithelioma-like carcinoma fromthe thyroid gland is extremely rare. We recently experienced a case of lymphoepithelioma-likecarcinoma of thyroid gland in a 28-year-old female, who presented a thyroid nodule that wassuspicious of papillary carcinoma. We report this unusual case of lymphoepithelioma-like carcinomaof thyroid gland with a brief review of literature.

Pleomorphic adenoma is the most common benign neoplasm of the parotid gland and it accountsfor approximately 80% of all reported tumor from parotid. Recurrence rate was notedas 20-45% and high risk factors related to recurrence were the following: over 40 years ofage, women, over 30 mm mass size, below 10 mm safety margin, tumor puncture and tumorspillage during surgery, relation to the facial nerve, tumor site, surgical procedure. We experienceda 45-year-old woman who presented a huge left parotid mass. She had a huge parotid pleomorphicadenoma that was removed 18 years ago but had recurred 8 years ago. We removed themass and obtained good postoperative results.

복굴절 재료를 이용하여 비점수차를 감소시킨 누진다초점 렌즈의 연구

노영진,김달영 한국물리학회 2010 새물리 Vol.60 No.3

The concept of a new kind of pregressive addition lens was developed by using a simulation study with the ZemaxTM lens design program adopting birefringent materials as lens glass. The results of the numerical analyses revealed that the astigmatism of birefringent (calcite) progressive addition lenses could be improved on the periphery by about 6 % as compared with general standard progressive addition lenses. From these results, if an appropriate form birefringence is used in the lens manufacturing process, improvement of optical quality of the progressive addition lenses can be expected. 누진다초점 렌즈의 재료로 복굴절 물질을 적용함으로써 새로운 개념의 누진 다초점 렌즈를 Zemax 상용 프로그램을 이용한 전산모사법으로 설계하여 보았다. 비점수차 분석 결과 표준적인 누진 다초점 렌즈 설계에 복굴절 재료(방해석)를 적용시킬 경우 렌즈 주변부의 비점수차가 약 6% 정도 감소하는 것으로 나타났다. 이러한 결과에 의하여, 렌즈의 제작과정에서 발생하는 형상 복굴절을 적절하게 이용한다면 누진다초점 렌즈의 광학적 성능을 향상시킬 수 있을 것으로 예상된다.

우리나라 제조업 기업의 투자행태에 대한 연구

노영진,김진웅 통계청 2014 통계연구 Vol.19 No.2

본 연구에서는 외환위기 이후부터 나타나는 국내 투자위축 현상을 기업의 투자행태의 변화에서 찾아보고자 한다. Kis-Value III에서 제공하는 국내 상장 제조업 기업 자료를 바탕으로 미래의 기대수익(토빈 q)과 기업의 내부자금시장(총자산대비 현금흐름)이 투자에 영향을 미치는 투자함수를 설정하여, 2000년 이후 이러한 요인에 대한 투자의 반응도 변화를 살펴보았다. 실증분석 결과, 2000년 이후 국내 기업들의 투자의 미래 기대수익과 현금흐름 민감도가 크게 하락하였는데, 기대수익에 대한 민감도 하락이 주요하게 변화된 것으로 나타났다. 기업규모별로 보았을 때, 미래 기대수익에 대한 투자반응도 하락이 제조업 내 대기업에 더욱 크게 나타났으며, 또한 제조업내 중소기업의 경우 기본적으로 매우 낮은 수준의 기대수익에 대한 투자반응도가 관찰되어 투자위축의 주요한 원인이 되는 것으로 분석되었다. The shrinkage of investment in Korea has been observed since the financial crisis at 1997. Our purpose of this study is to investigate and test whether the shrinkage has been caused by change in investment behavior. For the following empirical analysis, we use manufacturing firm level data obtained from the Kis-Value III database. In the basic investment function, we assume that an investment is determined by future expected return, i.e. Tobin’s q, and by a ratio of cash flow to total asset. In addition, we introduce the period effect in each explanatory variable in order to investigate change of investment behavior. Main empirical results are as follows. First, for all manufacturing firm, investment sensitivities against a future expected return and a ratio of cash flow have all decreased since 2000. However, considering the latter sensitivity has decreased more than the former one, the major cause of investment shrinkage seems to be the change in investment sensitivity against future expected return. Second, when we investigate the change of investment behavior by firm size – a large enterprise and a SME-, downfall in investment sensitivity against a future expected return occurs clearly in a large enterprise rather than in a SME. Third, a SME has chronic low investment sensitivity.

실리콘 산화막에 대한 Ta-Mo 합금 게이트의 열적 안정성

노영진,이충근,홍신남 한국전기전자재료학회 2004 전기전자재료학회논문지 Vol.17 No.4

The interface stability of Ta-Mo alloy film on SiO$_2$ was investigated. Ta-Mo alloy films were formed by co-sputtering method, and the alloy composition was varied by controlling Ta and Mo sputtering power, When the atomic composition of Ta was about 91%, the measured work function was 4.24 eV that is suitable for NMOS gate. To identify interface stability between Ta-Mo alloy film and SiO$_2$, C-V and XRD measurements were performed on the samples annealed with rapid thermal processor between $600^{\circ}C$ and 90$0^{\circ}C$. Even after 90$0^{\circ}C$ rapid thermal annealing, excellent interface stability and electrical properties were observed. Also, thermodynamic analysis was studied to compare with experimental results.

Color Doppler Energy(CDE):초기 10개월간의 경험

노영진 대한영상의학회 1996 대한영상의학회지 Vol.34 No.6

Purpose : Color Doppler Imaging(CDI) has shortcomings, including random noise, aliasing, and angle dependence. To overcome these, a method using CD US, termed power doppler or Color Doppler Energy(CDE), has recently been introduced. The purpose of this study was to show the clinical usefulness of CDE. Materials and Methods : We retrospectively analyzed the CDI and CDE of 61 cases(20 renal pseudotumors, 8 musculoskeletal inflammations, 17 epididymitis or epididymo-orchitis, 3 vaicoceles, 1 normal testis, 1 hepatocellualar carcinoma, 7 renal cell carcinomas, 1 renal angiomyolipoma, and 3 splenic varices). CDI and CDE scans were obtained at the same region with constant scan plane. The color gain was increased until noise first became perceptible, and scans were always obtained in such a way that the maximum amount of vascularity was shown. Thereafter, the vascularity, vascular displacement, and the vascular relationship between CDI and CDE were compared. Result : In 17 of 20 cases of pseudotumor in the kidney, normal vascularity was identified in CDI and CDE, but was more clearly visible in CDE. In three cases, there was no visible vascularity in CDI, but normal vascularity in CDE. In eight cases of musculoskeletal inflammation and 17 cases of epididymitis with or without or chitis, the vascularity was increased due to hyperemia, which was more prominently seen in CDE than in CDI. In three varicoceles, CDE appeared to be better in demonstration low velocity flow. In one patient who was suspected of having acute testicular torsion, CDE was helpful in excluding this suspicion. In one case of hepatocellular carcinoma, seven cases of renal cellcarcinoma, one case of renal angiomyolipoma, and three cases of splenic varices, CDE was better than CDI in showing the vascularity, vascular relationship, and vascular displacement. Conclusion : CDE is a potentially useful adjunct to standard CDI.
