유기박막 트랜지스터에서 문턱전압 이동의 모델링 및 시뮬레이션

정태호,Jung, Taeho 한국전기전자재료학회 2013 전기전자재료학회논문지 Vol.26 No.2

In this paper the author proposes a method of implementing a numerical model for threshold voltage ($V_{th}$) shift in organic thin-film transistors (OTFTs) into SPICE tools. $V_{th}$ shift is first numerically modeled by dividing the shift into sequentially ordered groups. The model is then used to derive a simulations model which takes into simulation parameters and calculation complexity. Finally, the numerical and simulation models are implemented in AIM-SPICE. The SPICE simulation results agree well with the $V_{th}$ shift obtained from an OTFT fabricated without any optimization. The proposed method is also used to implement the stretched-exponential time dependent $V_{th}$ shift in AIM-SPICE and the results show the proposed method is applicable to various types of $V_{th}$ shifts.

Threshold voltage shift has been observed from many thin-film transistors (TFTs) and the time evolution of the shift can be modeled as the stretched-exponential and -hyperbola function. These analytic models are derived from the kinetic equation for defect-creation or charge-trapping and the equation consists of only reversible reactions. In reality TFT's a shift is permanent due to an irreversible reaction and, as a result, it is reasonable to consider that both reversible and irreversible reactions exist in a TFT. In this paper the case when both reactions exist in parallel and make a combined threshold voltage shift is modeled and simulated. The results show that a combined threshold voltage shift observed from a TFT may agrees with the analytic models and, thus, the analytic models don't guarantee whether the cause of the shift is defection-creation or charge-trapping.

박막트랜지스터의 문턱전압 이동 시뮬레이션 방안

Threshold voltage shift caused by trapping and release of charge carriers in a thin-film transistor (TFT) is implemented in AIM-SPICE tool. Turning on and off voltages are alternatively applied to a TFT to extract charge trapping and releasing process. Each process is divided into sequentially ordered processes, which are numerically modeled and implemented in a computer language. The results show a good agreement with the experimental data, which are modeled. Since the proposed method is independent of TFT's behavior models implemented in SPICE tools, it can be easily added to them.

Stretched-Exponential 형태의 문턱전압 이동 모델의 SPICE구현

정태호,Jung, Taeho 한국반도체디스플레이기술학회 2020 반도체디스플레이기술학회지 Vol.19 No.1

Threshold voltage shift occurring during operation is implemented in a SPICE simulation tool. Among the shift models the stretched-exponential function model, which is frequently observed from both single-crystal silicon and thin-film transistors regardless of the nature of causes, is selected, adapted to transient simulation, and added to BSIM4 developed by BSIM Research Group at the University of California, Berkeley. The adaptation method used in this research is to select degradation and recovery models based on the comparison between the gate and threshold voltages. The threshold voltage shift is extracted from SPICE transient simulation and shows the stretched-exponential time dependence for both degradation and recovery situations. The implementation method developed in this research is not limited to the stretched-exponential function model and BSIM model. The proposed method enables to perform transient simulation with threshold voltage shift in situ and will help to verify the reliability of a circuit.

In this study, the influence of the intermolecular distance on the charge mobility in a pentacene thin-film was investigated. In order to increase the mobility which depends on the ${\pi}$-overlap between molecules, the intermolecular distance was shortened by compressive force along the conduction channel. Pentacene thin-film was fabricated on flexible substrates bent outward at different radii to stretch the gate dielectric surface and then the substrates were unbent, producing the compressive force to the film. The result showed that the mobility increased proportionally to the strain applied during the pentacene deposition and the molecular packing inside a grain was not optimal for the charge transport.

중국에서의 지식재산권의 권리충돌문제의 본질적인 해석에 관한 고찰

정태호(Jung, Tae-Ho) 한국정보법학회 2012 정보법학 Vol.16 No.1

중국에서는 지식재산권법의 충돌문제에 관하여 많은 연구가 이루어지고 있는데, 권리충돌의 법적성격에 대하여 ‘동일객체설’, ‘권리충돌부정설’, ‘경계범위모호설’이 논의되어 왔다. 그리고, 이러한 권리충돌문제에 대하여 합당하게 권리를 배치하고 적절한 구제를 부여하는 것이 중요한 문제로 되고 있다. 한편, 중국에서는 권리충돌의 원인으로서 지식재산권의 권리확장과 이익의식의 증대가 주로 논의되어 왔으며, 권리 충돌의 주요유형으로서는 상징성을 가진 지식재산권의 권리충돌, 지식재산권과 물권의 권리충돌, 상표권과 저작권 사이의 권리충돌, 지식재산권과 기타 민사권리의 충돌이 중국에서 주로 일어나고 있는 대표적인 권리충돌의 유형으로 정리되어 왔다. 그리 고, 중국에서의 지식재산권의 권리충돌문제는 상당히 사회적이고, 철학적인 원리를 기반으로 하여 그 해결방법을 구하고 있다. 이와 아울러 권리충돌의 원인을 지식재산 권의 권리확장과 이익의식의 증대라는 관점에서 분석하고 권리충돌의 조정원칙으로서 지식재산권법에서의 기본해결원칙인 선권리보호의 원칙을 중심으로 민법상의 기본원리인 권리남용금지 및 의사자치의 원칙을 보완적용하고 있다. 즉, 권리충돌의 문제를 민사법상의 기본법리를 근거로 하여 실제적인 해결방법을 제시하고 있다는 것도 그 특색이라고 할 수 있겠다. 지식재산권에서 물질적인 것만큼 정신적인 것을 중요시하는 중국 지식재산권법의 발전사에 따라서 권리충돌문제를 철학적인 관점에서 접근하고 있고, 사회주의이념을 채택하고 있는 국가이므로 권리충돌문제를 공공의 이익과 사회자원 및 이익의 공평한 분배적인 측면에서 그 해결책을 도모하고 있는 것도 중국에서의 문제해결방식의 특징이라고 하겠다. 우리나라에서도 이러한 지식재산권의 권리충돌문제에 대한 합리적인 해결방법에 관하여 다각적으로 고찰함으로써, 권리충돌이 가져오는 부정적인 영향은 권리들이 조화되는 유익한 결과로 전환시키고, 나날이 늘어나는 지식재산권의 권리충돌문제를 사회 및 경제발전으로 승화시키는 것에 대한 연구가 필요할 것이다. 그리고, 이러한 연구를 함에 있어서 중국에서의 지식재산권의 충돌문제에 대한 원인과 해결방법에 대한 이론들이 우리에게 시사하는 바가 매우 크다고 할 수 있겠다. Conflict Problems of intellectual property rights have been studied actively in China. ‘A Theory on an Identical Object’, ‘A Theory on Denial of Conflict of Rights’ and ‘A Theory on Obscurity of Boundary’ have been discussed about legal characters of Conflict of Rights. And it have been being regarded as important things to arrange rights properly and arbitrate in a dispute on this conflict problems of rights. Expansion of rights and increase of the awareness of interests in intellectual property rights have been being discussed mainly as causes of Conflict of Rights in China. Conflict of emblematic intellectual property rights, conflict between intellectual property rights and real rights, conflict between a trademark right and a copyright, and conflict between intellectual property rights and another civil rights have been recognized as representative types of conflict of rights in Chinese academic world. And Conflict problems of intellectual property rights in China have been discussed mainly in aspects of socialism and philosophy because China have already accepted socialism and have considered mental things as important value. Protection of pre-right, prohibition of abuse of right and principle of private autonomy have been considered very important as arbitration principles of conflict of rights in China. And thus conflict problems of intellectual property rights in China have been settled based on principles of civil law, public interests and fair distribution of interests. I think that we need to study proper methods of settlement on conflict problems of intellectual property rights in various aspects. We also need to study how we can change nagative effects into positive effects about conflict of rights and convert conflict problems of rights into the development of society and economy. And in studying this, theories on causes of conflict problems of intellectual property rights in China and solutions to this problems will be able to give us much help.

Background: Peripheral neuropathy is a frequent complication of chronic alcoholic patients. This study was to evaluate nutritional status, electrophysiological study, and to correlate alcohol history with Toronto Clinical Neuropathy Scoring System (TCNSS) and nutritional parameters. Methods: The study involved 34 patients aged 56.7±10.6 years who were diagnosed as chronic alcoholism according to DSM-IV criteria. Alcohol history was evaluated with multiplying Standard Drink (SD) with duration (year) of alcohol abuse and it was 495.24±384.81 (SD*years). Electrophysiological studies including sensory and motor conduction, H-reflex, F-wave were performed. TCNSS combines information obtained from score of symptoms, reflex test, sensory test. For nutritional status, laboratory test included hemoglobin, mean corpuscular volume (MCV), folate, albumin in blood. Results: Electrophysiological studies showed small amplitude of sensory nerve action potential in 5 (5.8%) cases of median nerve, 14 (41.1%) and 13 (38.2%) cases of superficial peroneral and sural nerve. For motor conduction studies, 3 (8.8%) and 3 (8.8%) cases of peroneal and tibial compound muscle action potential showed small amplitude. H-reflex of onset latency showed abnormal in 17 (50%) cases and F-wave of onset latency showed abnormal in 15 (44.1%) cases. Laboratory evaluation shows 2 (5.8%) cases of low hemoglobin, and 6 (17.6%) cases of low albumin level. There were no significant correlations between alcohol history and TCNSS, nutritional parameters. Conclusion: This study showed that nerve conduction studies were abnormal about half of the patients and sensory fibers are more frequently involved, especially in the lower limbs, mostly axonal neuropathy. Serum albumin deficiency was the most frequent abnormal nutritional parameter. There were no correlations between alcohol history and Toronto Clinical Neuropathy Scoring System, nutritional parameters.

중국의 특허쟁송 제도의 발전방향에 관한 고찰

정태호(Taeho Jung) 강원대학교 비교법학연구소 2018 江原法學 Vol.53 No.-

중국에서는 효율적인 특허소송의 처리를 위해 특허를 포함한 지식재산권 사건을 전문적으로 처리하는 지식산권법원을 베이징, 상하이, 광저우에 설치하였다. 그리고 그 외에도 지식재산 전문재판정도 다른 지역의 법원 내에 설치하여 지식재산권 사건을 전문적으로 처리할 수 있게 하였다. 현재는 지식산권법원에서 특허에 관한 민사소송과 행정소송만을 처리하고 있지만, 중국의 최고인민법원은 관련 사건에 대하여 형사소송도 함께 처리하는 3 in 1(三合一) 심리를 채택해서 특허에 관한 민사, 형사 및 행정사건을 모두 하나의 지식재산법정에서 집중하여 통일적으로 심리하는것을 추진하고 있다. 중국의 지식산권법원에서는 기술조사관 시스템을 적극적으로 도입 및 활용하여 특허소송 사건을 법관이 정확하게 판단할 수 있도록 보조하게 함으로써, 특허재판을 효율적으로 운영할 수 있도록 하고 있으며, 이러한 기술조사관 시스템을 지식산권법원 이외의 법원에까지 점차 확대하여 나가고 있기도 하다. 중국 최고인민법원은 사법해석을 제정하는 것에 의해 재판기준의 통일성을 도모하고 관련 규정들을 정비하여 재판의 객관적인 판단이 이루어지도록 하고 있다. 그리고 사법의 공개 및 투명도를 중시하는 정책을 중국 최고인민법원은 추진하고 있다. 특히 베이징지식산권법원, 상하이지식산권법원 및 광저우지식산권법원은 특허소송 사건의 전문적이고 신속한 처리를 하고 있으며, 심리과정도 투명하게 공개하고 있다. 중국에서도 특허쟁송 제도에 관하여 민사적인 구제절차, 형사적인 구제절차 및 행정적인 구제절차가 있다. 그리고 국가지식산권국의 전리복심위원회에서 특허심판에 관한 사건을 처리하고, 이에 대한 불복소송은 지식산권법원에서 처리하고 있다. 이러한 중국의 특허쟁송의 각 구제절차마다 중국 제도만의 독특한 특징들이 있는데, 이것은 우리나라의 특허쟁송 제도의 운영에 있어서 많은 것을 시사해 준다고 할 수 있다. 결국 형사소송에 관한 지식재산 사건 전담 처리법원으로의 전속관할 문제 및 특허권 등에 관한 소의 범위에 관한 전속관할 문제 등을 해결해 나가는 것과 관련해서 이상에서 살펴본 중국의 특허쟁송 제도의 발전 방향을 참조할 필요가 있다고 생각된다. The Supreme People"s Court of China has made the Intellectual Property Courts in Beijing, Shanghai, and Guangzhou, which professionally handle intellectual property cases involving patents in patent litigation. In addition, intellectual property courtrooms also have been set up in the courts of other regions for the professional handling of intellectual property cases. Currently, only the civil litigation and the administrative litigation regarding patents are handled by the Intellectual Property Courts, but the Supreme People"s Court of China is trying to adopt “3 in 1 judicial review” which also handles the criminal litigation together on the related cases in a single intellectual property courtroom. The Intellectual Property Courts of China actively introduces and utilizes the technical examiner system to help judges accurately judge the patent litigation cases, thereby enabling efficient operation of patent litigation review. This system is also gradually being expanded to other courts. The Supreme People"s Court of China has enacted “the Judicial Interpretation” to promote the unity of the judicial standards and to modify the relevant provisions so that objective judgments of the judiciary can be made. And the Supreme People"s Court of China is pursuing a policy of emphasizing the transparency and disclosure of justice. In particular, the Beijing Intellectual Property Court, the Shanghai Intellectual Property Court and the Guangzhou Intellectual Property Court are handling the patent litigation cases professionally and expeditiously, and the judicial review process is transparently disclosed. In China, there are also civil remedies, criminal remedies and administrative remedies for patent lawsuit system. The Patent Re-examination Board of the State Intellectual Property Office handles cases related to patent trials, and the litigations for cancellation of the trial decisions are handled by the Intellectual Property Court. In the cases of China, there are unique characteristics of the Chinese system in each remedy of patent litigation, which suggest us many things about the operation of the patent lawsuit system in our country. In the end, it is necessary to refer to the course of development of China"s patent lawsuit system as described above in order to solve the problems of the exclusive jurisdiction on the intellectual property litigations concerning the criminal cases and the exclusive jurisdiction on the lawsuits concerning patent right, etc..

중국 상표법상 치명상표의 개념 및 인정방식에 대한 연구

정태호(Tae-Ho Jung) 세창출판사 2008 창작과 권리 Vol.- No.53

The concept of well-known mark in Chinese Trademark Law isn't definitely understood and it is still difficult for foreigners to understand its concept exactly. Therefore, it is needed to define the concept of well-known mark and study determination methods of Well-known mark in Chinese Trademark Law. China is a party to the WTO, therefore it is committed to TRIPs and WIPO JOINT RECOMMENDATION CONCERNING PROVISIONS ON THE PROTECTION OF WELL-KNOWN MARKS. And thus, an well-known mark can be protected and enforceable effectively. The revised Trademark Act Article 13, 14, effective on December 2001 and the regulation entitled "Provisions on the Determination and Protection of Well-Known marks", effective on June 2003, have helped to recognize Well-Known status of a number of Chinese trademarks. On the other hand, an unregistered trademark, if identified by the Trademark Office as an well-known mark in the relavant sector of the public, is as enforceable as a registered trademark be. And there become to be two main methods to determine Well-Known mark; One is by administrative means if there are oppositions or trials, the other is through the People's Court if there are suits. The Article 13 states that "Where a trademark in respect of which the application for registration is filed for use for identical or similar goods is a reproduction, imitation or translation of another person's trademark not registered in China and likely to cause confusion, it shall be rejected for registration and prohibited from use. Where a trademark in respect of which the application for registration is filed fdr use for non-identical or dissimilar goods is a reproduction, imitation or translation of the well-known mark of another person that has been registered in China, misleads the pub1ic and is likely to create prejudice to the interests of the well-known mark registrant, it shall be rejected for registration and prohibited from use." and the Article 14 states that "Account shall be taken of the fol1owing factors in establishment of a well-known mark: ⑴ reputation of the mark to the relevant public; (2) time for continued use of the mark; (3) consecutive time, extent and geographical area of advertisement of the mark; (4) records of protection of the mark as a well-known mark; and (5) any other factors relevant to the reputation of the mark." And this provisions have accepted relavant provisions of WIPO JOINT RECOMMENDATION CONCERNING PROVISIONS ON THE PROTECTION OF WELL-KNOWN MARKS. This provisions in China leads us to think that it is needed to make the definite standards and concrete method determining Well-Known mark in our Trademark Law. Therefore, I think that Korea Intellectual Property Office also need to make the definite regulations about determining Well-Known mark like the cases of Chinese Trademark Law and regulations.
