Modeling and Simulation of Spiral Inductors in Wafer Level Packaged RF/Wireless Chips

In this paper, embedded rectangular spiral inductors on Wafer-Level Packaged (WLP)RF/wireless chips were studied with 3D (three-dimensional) EM (electromagnetic)simulations. The performance of spiral inductors fabricated with various geometrical and technological parameterswas analyzed. It is shown that Q (the quality factor) and f _res (theself-resonance frequency) could be improved by using the thick insulator layer and thick/wide metal line,which are fabricated by WLP technology. The value of Q could be over 60 at 20 GHz for such embeddedcomponents, attesting a significant improvement compared to the conventional on-chip counterparts in CMOS. Throughthis study, optimal structures for such components are identified and guidelines for design and fabrications arederived. Finally, a method to estimate the inductance of rectangle spiral inductors is developed. It is useful todetermine the approximate structure of an inductor quickly before detailed 3D EM simulation, which may cost a longtime.     

An Approach to the Market Analysis of KoreaSat Services

The field of marketing research in the satellite communication services is still in the early stage of its development. Particularly, in Korean domestic satellite service market, many theoretical and methodological opportunities now exist. In this paper we develop a model, which identifies target markets and promising application services in Korean satellite communication service market. One key contribution of this paper is a modeling approach to the assessment of market potential and priorities of the application services in each Korean industry. We define and estimate the degree of attractiveness for each segmented market which represents the market potential estimated by current usage of terrestrial services and each market segment's willingness to adopt satellite technology. Since all possible satellite application services are not equally important in the market, they should be differentiated in terms of the likelihood of success. We introduce another index prioritizing application services by tying together three important factors affecting Korean satellite service demand. Some marketing implications of model results are also discussed. Finally the findings of our model are compared with those of other similar studies.

纳米磨料对GaAs晶片的抛光研究

通过均相沉淀法制备了纳米CeO2和Al2O3粉体,研究了在相同抛光条件下纳米CeO2、SiO2和Al2O3磨料对GaAs晶片的抛光效果,并用原子力显微镜观察抛光表面的微观形貌并测量表面粗糙度。结果表明,使用纳米CeO2磨料抛光后的表面具有最低的表面粗糙度,在1μm×1μm范围内表面粗糙度Ra值为0.740nm,而且表面的微观起伏更趋于平缓。文中还探讨了GaAs晶片化学机械抛光材料去除机理,考虑了纳米磨料在抛光条件下所发生的自身变形,并分析了纳米磨料硬度对抛光表面粗糙度的影响,初步解释了在相同的抛光条件下不同硬度的纳米磨料为什么具有不同的抛光表面粗糙度。
