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.

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.

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.

박막트랜지스터의 병렬형 가역과 비가역 문턱전압 이동에 대한 모델링

정태호,Jung, Taeho 한국전기전자재료학회 2016 전기전자재료학회논문지 Vol.29 No.7

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.

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.

정태호 ( Tae Ho Jung ),김혁중 ( Hyuk Joong Kim ) 한양대학교 법학연구소 2012 법학논총 Vol.29 No.4

Recently, Supreme Court judged that a patent right has not been effective on the other worked invention by accepting defense of invalidation of patent registration based on a obvious absence of inventive step in a patent right infringement litigation(Supreme Court Decision No.2010Da95390; January 19. 2012). And this determination was also based on an abuse of right about exercising the patent right. In case Patent right has been granted against inventive step, a requirement for patent registration and a reason for invalidation of patent registration, this right should have been only determined as being invalid by a invalidation trial based on the former standard of determination. But Supreme Court has determined whether a patent registration was invalid or not about that in a patent right infringement litigation. In the above Court`s decision, it was determined that a patent didn`t have obviously inventive step and further exercising the patent right fell in an abuse of right in a patent right infringement litigation against the above Patent Law`s principle and the former Supreme Court decision. I think that the determination of the above Court like this is unreasonable, since determination of invalidation of patent and an abuse of right based on an absence of inventive step in a patent right infringement litigation is against Patent Law`s principle and official rights of administrative acts. Therefore, I think that it is proper to revise patent law or apply protest of free technology to patent right infringement case instead of abuse of right. In conclusion, this paper critically analyses and examines a number of problems from the subject case.

디자인보호법상 물품의 기능을 확보하는 데에 불가결한 형상만으로 된 디자인에 관한 고찰

정태호(Jung, Tae-Ho) 숭실대학교 법학연구소 2016 法學論叢 Vol.35 No.-

디자인보호법 제34조 제4호에서는 “물품의 기능을 확보하는 데에 불가결한 형상만으로 된 디자인”은 디자인등록을 받을 수 없다고 규정하고 있다. 그런데 해당 규정에 관한 대법원 판결로서는 유일하게 대법원 2006. 1. 13. 선고 2005후841 판결(이하, “대상판결”이라 함)만이 존재하므로, 대상판결을 분석함으로써 해당 규정의 판단 법리를 검토해 볼 필요가 있다. ‘물품의 기능을 확보하는 데에 불가결한 형상’이란 물품의 기술적 기능을 확보하기 위해 필연적으로 결정되어 버린 형상을 말하는데, ‘물품의 기능에 관련된 형상’이라고 하더라도 그 기능을 확보할 수 있는 선택 가능한 대체적인 형상이 존재한다면 해당 규정에서 말하는 물품의 기능적 형상에 해당한다고 할 수 없다. 대상판결은 ‘물품의 기능을 확보하는 데에 불가결한 형상’의 범위에 대해서 수요자들이 그 물품을 볼 때 특정 형상을 당연히 있어야 할 부분으로 여김으로써 그 형상에 대해서 별다른 심미감을 느끼지 못하는 정도까지 포함되어야 한다는 것을 보여주고 있다. 그리고 대상판결을 통해서 대법원이 디자인의 기능성 판단에 있어서 ‘유일기능기준’을 적용하고 있음도 역시 확인할 수 있다. 결국 디자인에서 그 본질과 관련되어 기능성과 장식성 간의 경계는 더욱 모호해지고 있고, 그 경계를 명확히 구분하는 것이 점점 어려워져 가는 시대적 상황 속에서 디자인보호법상 “물품의 기능을 확보하는 데에 불가결한 형상만으로 된 디자인”에 관한 해석은 더욱 중요하여 질 것이다. 따라서 대상판결에서의 판단 법리를 토대로 하여 이에 관한 심도있는 연구가 앞으로 구체적으로 이루어져야 한다. Article 34, (4) of the Design Protection Act states that “a design consisting solely of a shape that is indispensable to secure the functions of the article” shall not be registered. By the way, there is only Supreme Court Decision 2005Hu841 Decided January 13, 2006(hereinafter referred to as “the subject decision”) as a Supreme Court Decision related to this provision. Therefore, we need to study legal principles of determination on this provision by analyzing the subject decision. ‘A shape that is indispensable to secure the functions of the article’ means a shape that is decided to be indispensable to secure the functions of the article and ‘a shape related to the functions of the article’ can’t be a functional shape of the article on this provision if there is any alternative shape to secure the functions of the article. The subject decision shows that the scope of ‘a shape that is indispensable to secure the functions of the article’ should reach the extent that consumers don’t feel aesthetic particularly on the shape by regarding the shape as a indispensable part when they see the article. And according to the subject decision, we can see that Supreme Court have applied ‘solely functional standard’ to determining the functionality of design. In conclusion, because of ambiguous boundary between functionality and ornamentality on the nature of a design, it becomes to be more difficult for us to distinguish between the two and thus it will be more important that we determine whether a certain design is “a design consisting solely of a shape that is indispensable to secure the functions of the article” in Design Protection Act. Therefore, we should make an in-depth study on this provision concretely from now on based on legal principles of determination in the subject decision.

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..
