In this parer, hump characteristics of short-channel nMOSFETs induced by moistures of the ILD(inter-layer dielectric) layer in the shallow trench isolation (STI) process are investigated and the method for hump suppression is proposed Using nMOSFETs with various types of the gate and a measurement of TDS-APIMS (Thermal Desorption System-Atmospheric Pressure ionization Mass Spectrometry), hump characteristics were systematically analyzed and the systemic analysis based hump model was presented; the ILD layer over poly-Si gate of nMOSFET generates moistures, but they can't diffuse out of the SiN layer due to the upper SiN layer. Consequently, they diffuses into the edge between the gate and STI and induces short-channel hump. In order to eliminate moisture in the ILD layer by out-gassing method, the annealing process prior to the deposition of the SiN layer was carried out. As the result, short-channel humps of the nMOSFETs were successfully suppressed.

For the application of fuel cell, the content and concentration of impurities in hydrogen stream must be classified. The purpose of this study is to provide analysis tool for the determination of impurities in hydrogen with ultra high purity. To produce UHT hydrogen, we purified hydrogen gas by both getter-based catridge and liquid-nitrogen soaked catridge. We compare two methods and propose new method to know about what is in hydrogen stream.

Objectives: The purpose of this study was to investigate a role of self-compassion in conflict resolution strategies among dating couples. Further, we examined conflict resolution strategies as mechanisms to explain in the relationship between self-compassion and relationship satisfaction. Method: Two hundred forty two dating couples were recruited. Actor and Partner Independence Model(APIM) was used to examine actor and partner effects of self-compassion on relationship satisfaction as well as conflict resolution strategies. The total of 4 APIMs, two positive conflict resolution strategies(i.e., positive emotional reactions, active coping) and two negative conflict resolution strategies(i.e., negative emotional reactions and hostility, avoidance) were analyzed. Positive conflict resolution strategies had only actor effect in the link between self-compassion and relationship satisfaction. That is, self-compassionate men and women were more likely to use positive conflict resolution strategies and, in turn, led to their higher relationship satisfaction. Both actor and partner effects were found in the negative conflict resolution strategy models. In terms of actor effect self-compassionate men and women were less likely to use negative conflict resolution strategies and that, in turn, led to their higher relationship satisfaction. In terms of partner effects we found that women's negative emotional reactions and hostility mediated the link between women's self-compassion and their male partners' relationship satisfaction. Men's avoidance mediated the link between men's self-compassion and their female partners' relationship satisfaction.

Given the interdependence of a marital couple, this study examined the effects of both cultural challenge and economic hardship on intention to divorce among the multicultural couple using the actor-partner interdependence model(APIM), and explored dyadic patterns of actor and partner effects. 415 couples(n=830) participated in this self-administered questionnaire study. Results of path analyses based on APIMs revealed that for Korean husbands perceived cultural challenge contributed positively to divorce intention of the couple showing both actor and partner effects, whereas for immigrant wives such perception showed only an actor effect. In contrast, perceived economic hardship among the husbands had little effect on divorce intention of both husbands and wives, whereas such perception by wives had both actor and partner effects on divorce intention. Results of dyadic pattern analyses performed by Bootstrap indicated the actor-only pattern and the couple pattern of perceived cultural challenge on divorce intention of husbands and wives respectively. In case of perceived economic hardship comparison of the effect size suggested the partner-only pattern and the actor-only pattern for divorce intention of husbands and wives respectively. These findings implied that in order to promote conjugal harmony and to prevent the multicultural family from being dissolved, Korean husbands need to develop greater cultural competence so as to tolerate cultural differences between the couple, whereas immigrant wives and their families need to develop greater economic competence so as to foster a hope for economic reliance.
