Abstract: A multilayer capacitor includes a body including dielectric layers and internal electrodes and external electrodes disposed on an external surface of the body and connected to the internal electrodes. The body includes a first surface and a second surface to which the internal electrodes are exposed, the first surface and the second surface opposing each other in a first direction, a third surface and a fourth surface opposing each other in a second direction which is a direction in which the dielectric layers are stacked, and a fifth surface and a sixth surface opposing each other in a third direction. At least one of the internal electrodes include a first bottleneck structure having a first directional length of a third-directional outer region smaller than an inner region thereof and a second bottleneck structure having a third directional length of a first directional outer region smaller than an inner region thereof.

Abstract: 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.

Abstract: In an apparatus and a method of measuring a thickness of a multilayer on a substrate, a spectrum of reflected light reflected from the substrate is measured. A plurality of recipe data, each corresponding to one of a plurality of hypothetical multilayers, is stored. One of the plurality of hypothetical multilayers is initially assumed to be the multilayer actually formed on the substrate. A plurality of theoretical spectra is calculated using one of the plurality of recipe data in accordance with various theoretical thicknesses of one of the plurality of hypothetical multilayers. The measured spectrum is compared with the plurality of theoretical spectra to determine a temporary thickness of the multilayer. A reliability of the temporary thickness of the multilayer is estimated. The temporary thickness is output as a thickness of the multilayer on the substrate when the reliability of the temporary thickness is within an allowable range.
