    摘要: An apparatus and method to inspect a defect of a semiconductor device. The amount of secondary electrons generated due to a scanning electron microscope (SEM) may depend on the topology of a pattern of a semiconductor substrate. The amount of secondary electrons emitted from a recess of an under layer is far smaller than that of secondary electrons emitted from a projection of a top layer. Since the recess is darker than the projection, a ratio of a value of a secondary electron signal of the under layer to a value of a secondary electron signal of the top layer may be increased in order to improve a pattern image used to inspect a defect in the under layer. To do this, a plurality of conditions under which electron beams (e-beams) are irradiated may be set, at least two may be selected out of the set conditions, and the pattern may be scanned under the selected conditions. Thus, secondary electron signals may be generated according to the respective conditions and converted into image data so that various pattern images may be displayed on a monitor. Scan information on the pattern images may be automatically stored in a computer storage along with positional information on a predetermined portion of the semiconductor substrate. When calculation conditions are input to a computer, each of scan information on the pattern images may be calculated to generate a new integrated pattern image.

    摘要: An apparatus for measuring a semiconductor device is provided. The apparatus includes a beam emitter configured to irradiate an electron beam onto a sample having the entire region composed of a critical dimension (CD) region, which is formed by etching or development, and a normal region connected to the CD region, and an analyzer electrically connected to the beam emitter, and configured to select and set a wavelength range of a region in which a difference in reflectance between the CD region and the normal region occurs, after obtaining reflectance from the electron beam reflected by a surface of the sample according to the wavelength of the electron beam. A method of measuring a semiconductor device using the measuring apparatus is also provided. Therefore, it is possible to minimize a change in reflectance due to the thickness and properties of the semiconductor device, and set a wavelength range to monitor a specific wavelength, thereby accurately measuring and analyzing a CD value of a measurement part of the semiconductor device.

    摘要: The present invention relates to alkoxysilane-substituted diene copolymers, organic and inorganic hybrid complex compositions comprising the same and a process for the preparation of the same. The alkoxysilane-substituted diene copolymers are prepared by reacting a diene copolymer substituted by epoxy or hydroxy groups with a silane compound. Thus prepared alkoxysilane-substituted diene copolymer is characterized by the facts that it is in organic solvents and it is capable of being cured at low temperatures. The present invention also relates to a composition prepared by mixing the said copolymer with inorganic fillers and/or coupling agents. The copolymer of the formula (1) has high reactivity with coupling agents since it possesses reactive silane groups and thus provides the diene polymer composition as having improved compatibility with inorganic fillers. In addition, when the copolymer of the formula (1) is added to a sol-gel reactant, a substitution reaction proceeds smoothly even under mild reaction conditions and thus it is possible to introduce the third functional group to copolymer blocks.
