Abstract: In order to allow detecting backscattered electrons (BSEs) generated from the bottom of a hole for determining whether a hole with a super high aspect ratio is opened or for inspecting and measuring the ratio of the top diameter to the bottom diameter of a hole, which are typified in 3D-NAND processes of opening a hole, a primary electron beam accelerated at a high accelerating voltage is applied to a sample. Backscattered electrons (BSEs) at a low angle (e.g. a zenith angle of five degrees or more) are detected. Thus, the bottom of a hole is observed using “penetrating BSEs” having been emitted from the bottom of the hole and penetrated the side wall. Using the characteristics in which a penetrating distance is relatively prolonged through a deep hole and the amount of penetrating BSEs is decreased to cause a dark image, a calibration curve expressing the relationship between a hole depth and the brightness is given to measure the hole depth.

Abstract: A charged-particle-beam device is provided with a data processing unit that removes, from a detector signal, the effect that scattering of a primary charged-particle beam before the primary charged-particle beam reaches a specimen has on the spot shape of the primary charged-particle beam. For example, when using an electron microscope to observe a specimen in a non-vacuum atmosphere, the effect that scattering of a primary charged-particle beam due to a barrier film or a gas present in a non-vacuum space has on the spot shape of the primary charged-particle beam is removed from a signal acquired by a detector. This makes it easy to obtain high-quality images.

Abstract: Beforehand, the device characteristic patterns of each critical dimension SEM are measured, a sectional shape of an object to undergo dimension measurement is presumed by a model base library (MBL) matching system, dimension measurements are carried out by generating signal waveforms through SEM simulation by inputting the presumed sectional shapes and the device characteristic parameters, and differences in the dimension measurement results are registered as machine differences. In actual measurements, from the dimension measurement results in each critical dimension SEM, machine differences are corrected by subtracting the registered machine differences. Furthermore, changes in critical dimension SEM's over time are monitored by periodically measuring the above-mentioned device characteristic parameters and predicting the above-mentioned dimension measurement results. According to the present invention, actual measurements of machine differences, which require considerable time and effort, are unnecessary.

Abstract: A model based measurement method is capable of estimating a cross-sectional shape by matching various pre-created cross-sectional shapes with a library of SEM signal waveforms. The present invention provides a function for determining whether or not it is appropriate to create a model of a cross-sectional shape or a function for verifying the accuracy of estimation results to a conventional model based measurement method, wherein a solution space (expected solution space) is obtained by matching library waveforms and is displayed before measuring the real pattern by means of model based measurement. Moreover, after the real pattern is measured by means of model based measurement, the solution space (real solution space) is obtained by matching the real waveforms with the library waveforms and is displayed.
