TLP 평가기법을 이용한 Diode type의 ESD 보호소자 특성 평가
이태일,김홍배,Lee, Tae-Il,Kim, Hong-Bae 한국반도체디스플레이기술학회 2007 반도체디스플레이기술학회지 Vol.6 No.4
In paper, We evaluated for various diode type ESD protection device using TLP measurement method. An Evaluation diode is divided to Enclosed type and Stripe type as pattern style in extensive. These diodes is split up followed factor that Anode-to-Cathod space, N+ region width, Multi type and Contact to Active space. After a TLP measurement, we can be got the Vt2, It2 by I-V characteristic values. In the results, diode of enclosed type is present relatively higher Current capability(It2) than stripe type in a same voltage conditions. And the Second-breakdown voltage(Vt2) were that Stripe type's diode higher than Enclosed type's diode as have $14{\sim}15V$. Finally we suggest the best diode design condition as ESD protection device using entire consequence.

Conventional CMOS 공정을 위한 GGNMOS Type의 ESD 보호소자의 TLP 특성 평가
이태일,김홍배,Lee, Tae-Il,Kim, Hong-Bae 한국전기전자재료학회 2008 전기전자재료학회논문지 Vol.21 No.10
In this paper, we deal with the TLP evaluation results for GGNMOS in ESD protection device of conventional CMOS process. An evaluation parameter for GGNMOS is that repeatability evaluation for reference device($W/L=50\;{\mu}m1.0\;{\mu}m$) and following factors for design as gate width, number of finger, present or not for N+ gurad -ring, space of N-field region to contact and present or not for NLDD layer. The result of repeatability was showed uniformity of lower than 1 %. The result for design factor evaluation was ; 1) gate width leading to increase It2, 2) An increase o( finger number was raised current capability(It2), and 3) present of N+ gurad-ring was more effective than not them for current sink. Finally we suggest the optimized design conditions for GGNMOS in evaluated factor as ESD protection device of conventional CMOS process.

사회과학(社會科學)에 있어서의 론리실증주의적(論理實證主義的) 연구방법론(硏究方法論)
이태일 ( Tae Il Lee ) 東亞大學校附設 石堂傳統文化硏究院 1981 石堂論叢 Vol.5 No.-
Logical positivism which came into being in the early 1920s in Germany with the establishment of the so-called Vienna Circle by Moritz Schlick has become one of the mainstreams in the methodology of social sciences in Korea as well as in the United States after World War II. It contributed to a myth of "methodology". However, such an exogenous methodology should be examined and reviewed from the viewpoint of autonomous development of social sciences in Korea. In this connection, the objective of this study is to clarify the characteristics and acceptability of logical positivist view of social sciences. For the sake of this objective, this study has clarified in the second chapter the epistemological basis of logical positivism. According to the logical positivists, scientific knowledge can be obtained through sense-experience; only sense-experience can give us an intersubjectively verifiable or at least falsifiable account of the social world. In other words, logical positivists recognized only the data of experiences as the grounds of validity for scientific knowledge. In the third chapter, this study reviewed the practices of logical positivist view of social sciences i.e. behavioral sciences. The behavioral sciences are characterized by its concentration on the behavior of human beings, and by the explicit advocacy of scientific method. According to the behavioral scientists, the real stuffs of social sciences are not the institution, history and law, but the behaviors of individuals. And their objectives are the development of empirical generalizations and a systematic theory. Thus the social sciences are, according to them, unified because of their common interests in behavior and scientific method. In conclusion, the writer examined in the last chapter the acceptability of logical positivist view of social sciences in Korea. It was concluded that logical positivism and the theory of behavioral sciences might be acceptable in Korea, not as the only possible methodolgy and theory applicable to any situations and problems, but as one of the methodologies and theories to resolve the societal problems of Korea.
