    摘要: A method of analyzing ions adsorbed on a surface of a mask for pattern formation of a semiconductor device, and an apparatus using the same are disclosed. The ion analyzing method includes: filling a heating container within a main chamber with a predetermined amount of a solvent; immersing a mask in the solvent-filled heating container; raising an internal pressure of the chamber to a predetermined level by supplying gas into the chamber; separating ions from a surface of the mask by heating the solvent within the heating container at a predetermined temperature for a predetermined period; and analyzing the ions by collecting the solvent.

    摘要: A method of measuring a critical dimension may include forming an object pattern on a substrate and forming a plurality of reference patterns on the substrate, wherein each of the plurality of reference patterns has a different critical dimension. An optical property of each of the plurality of reference patterns may be measured to provide a respective measured optical property for each of the reference patterns, and an optical property of the object pattern may be measured to provide a measured optical property of the object pattern. The measured optical property of the object pattern may be compared with the measured optical properties of the reference patterns, and a critical dimension of the object pattern may be determined as being the same as the critical dimension of the reference pattern having the measured optical property that is closest to the measured optical property of the object pattern. Related devices are also discussed.

    摘要: A condensation particle counter measures the number of ultra-fine particles by growing the ultra-fine particles through a condensing process. The counter includes a capillary in which vapor of operating liquid is condensed and the ultra-fine particles grow. An insulating material surrounds the capillary to shut out heat flow between the capillary and the environment. The condensation particle counter can use various operating liquids including alcohol and water, and can be also applied to semiconductor clean rooms.
