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.

A plural number M (M&#x2267;2) of block cipher encryption units perform, in a block order, either encryption processing or decryption processing for data of a series of blocks each having a predetermined data size and included in a data unit. The plural number of block cipher encryption units perform either encryption of decryption for the data unit by repeating processing in the block order. Every time processing of a data unit starts, a block cipher encryption unit configured to process the data of the nMth (nM&#x3c;N, N represents a block count) block in nth (n&#x2267;1) processing generates an initial mask value to be used for the encryption or decryption.
