Zusammenfassung:To provide a method and apparatus for acquiring a cross-sectional image of a stacked capacitor capable of realizing the time (or cost) efficiency in acquiring the cross-sectional image of the stacked capacitor and fine resolution of the cross-sectional image of the stacked capacitor.SOLUTION: A stacked capacitor comprises a body having a plurality of internal electrodes and a plurality of dielectric layers stacked alternately. An apparatus for acquiring a cross-sectional image of the stacked capacitor may comprise: a camera for acquiring an enlarged image of a cross-section of the stacked capacitor where the plurality of internal electrodes and the plurality of dielectric layers of the body are exposed; a lens positioned between the cross-section and the camera; a light source outputting visible light; and a first polarizer polarizing and outputting light input from between the light source and the cross-section.SELECTED DRAWING: Figure 1a 【課題】積層型キャパシタの断面イメージを獲得する時間(又はコスト)の効率性と、積層型キャパシタの断面イメージの微細な分解能を得ることができる積層型キャパシタの断面イメージ獲得装置及び方法を提供する。【解決手段】本発明の一実施形態による積層型キャパシタの断面イメージ獲得装置は、複数の内部電極と複数の誘電体層が交互に積層された本体を含む積層型キャパシタにおいて、本体の複数の内部電極と複数の誘電体層が露出される断面の拡大したイメージを獲得するカメラと、断面とカメラとの間に配置されたレンズと、可視光線を出力する光源と、光源と断面との間から入力される光を偏光させて出力する第1偏光器と、を含むことができる。【選択図】図1a
