查询词典 contamination

Now, the imposex status in females of Thais clavigera and Cantharus cecillei in 17 sites was investigated to evaluate the organotin contamination along Xiamen Bay during 2006 and 2007.

In invasive clostridial infections, spores reach tissue either by contamination of traumatized areas Or from the intestinal tract.

组织肿胀影响血液的供应。细菌所产生的引起坏死的毒素和透明质酸酶均有利于感染的扩散。

Consequently, for short exposure time the lower molecular-weight condensable oAMCs may be a more important contamination problem than the higher molecular-weight condensable ones.

此外，利用吸附沈积动力模式计算，将获得晶圆於制程中最大允许浓度或最大可曝露时间建议值，此结果可提供国内半导体相关产业在解决日渐严重oAMCs问题与发展微污染控制技术之参考。

Semiconductor industry has been a central figure to the economic growth in Taiwan, especially for the fabrication sector of integrated circuit that has evolved into world-leading status. The fabrication technology advances so far that the feature size (or critical line-width) of IC devices has now broken the 0.1 ?慆 barrier and into the nano-scale age. This progress discloses that the traditional definition of a "cleanroom" environment may become increasingly inadequate because prevention of particulate contamination may no longer be a critical issue. As the condensable organic airborne molecular contaminants depositing on wafer surfaces, it results in deterioration on device performance and reduces semiconductor device yield.

半导体产业已成为我国最重要的经济发展产业，其中积体电路制造技术的快速发展，使我国早已跃升成为世界晶圆代工重镇之一，然而当制程的关键线宽尺寸突破0.1微米而正式进入奈米等级之际，传统针对微粒污染控制所设计之洁净室将无法符合气态分子污染物之洁净需求，其中凝结性有机分子污染物质(organic airborne molecular contaminants)一旦沈积吸附於晶圆表面，将导致元件缺陷与制程良率下降。
