PROBLEM TO BE SOLVED: To provide an inspection device capable of obtaining an image with high contrast and S/N at an edge of a mesa structure.SOLUTION: An inspection device comprises: beam generation means for generating any of a charged particle and an electromagnetic wave as a beam; a first optical system which guides a beam to an inspection object held in a working chamber and irradiates the inspection object with the beam; a second optical system which detects a secondary charged particle generated from the inspection object; and an image processing system which forms an image on the basis of the detected secondary charged particle. A central part of the inspection object is provided with a central flat part 390. A peripheral edge of the central flat part 390 is provided with a peripheral edge flat part 392 via a step 391. An electric field correction plate 400 is installed around the step 391. A surface voltage comparable to the surface voltage to be applied to the inspection object is applied to an electrode 401 on a surface of the electric field correction plate 400.

PROBLEM TO BE SOLVED: To provide a mesh for holding a sample which hardly damages the distal end of the sample and is highly suitable for general purposes (unnecessary to make special the shape of a recess (concave) for a sample holder to be mounted with a mesh) and an element analysis method.SOLUTION: A mesh for holding sample 14 has a ring plate shape for use in a transmission electron microscope. The mesh comprises a first and a second mesh formed by dividing the ring plate by a groove 22 provided on the upper surface of the ring plate into a first and a second semi-ring plate shape. The second mesh can be bent from the groove in a direction toward the lower surface of the ring-shaped plate and folded under the lower surface of the first mesh in the state where a sample is mounted on the first mesh of the ring plate shape including the first and the second mesh.

PROBLEM TO BE SOLVED: To provide a method of correcting astigmatism of an electro-optical column in an electron emission microscopic spectral device. SOLUTION: This method includes a step of forming a reference structure (100B) on a surface of a testpiece containing a structure which is to be an imaging object, a step of imaging the reference structure by a microscopic spectral device by using secondary electrons and using inner shell level photo-electrons, and a step of removing an astigmatic defect coming out while imaging the reference structure by using the secondary electrons and inner shell level photo-electrons. The material of the reference structure is selected so that a contrast C between an average strength Ia of the material of the reference structure and an average strength Ib of the material of the testpiece may become as shown in a formula (1).

Abstract:
PROBLEM TO BE SOLVED: To perform the analysis of an element with high precision, by easily and accurately adjusting a sample to the position and angle which is optimal for both of a microscopic mechanism and an element-analysis mechanism and by allowing a microscopic image and the three-dimensional data of the element-analysis mechanism to accurately correspond to each other to easily correct the scale or the deficiency of detection efficiency at three-dimensional reconstruction in a composite element analyzer constituted by loading the microscopic mechanism for observing the sample with the element analysis mechanism of the sample. SOLUTION: A function (first moving part 35) for performing the respective parallel movements in X-axis, Y-axis and Z-axis directions and the respective rotational movements around an X-axis and a Y-axis is added to a sample holder 31 on which the sample 11 is installed, and a function (second moving part 26) for performing the rotational movement around a Z-axis coinciding with the optical axis in the electron microscopic mechanism is added to a position-sensitive detector 3 for detecting the element dissociated from the sample 11.
