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.
