Abstract:
A scanning probe microscopy system has a cantilever having a probe at a distal end thereof and a heating unit for heating the sample. A moving unit effects relative movement between the cantilever probe and the sample to bring the cantilever probe into contact with a surface of the sample for measuring a property of the sample. A shielding unit shields between the cantilever probe and the sample during heating of the sample by the heating unit.
Abstract:
An electron beam apparatus has an optical axis, an electron beam source for generating an electron beam directed along the optical axis, and a magnetic field lens having an axis coincident with the optical axis for focusing the electron beam onto a sample which is subjected to a negative voltage so that secondary electrons are emitted from the sample. The magnetic field lens has a conductive cylinder surrounding a part of the optical axis to permit the passage therethrough of an electron beam from the electron beam source. A first detector detects secondary electrons emitted by the sample in a direction away from the optical axis and is disposed at a position generally confronting the conductive cylinder. A second detector is disposed over the conductive cylinder. A Wien filter deflector deflects secondary electrons emitted by the sample toward and for detection by the second detector. The Wien filter deflector is disposed on the optical axis and between the conductive cylinder and the second detector.
Abstract:
A self-detecting type cantilever for an atomic force microscope (AFM) has an electro-flexural conversion element for converting a flexural amount of the cantilever into an electric current or voltage, a temperature measurement element disposed at a front end portion of the cantilever for measuring a temperature, and a heating element disposed at the front end portion of the cantilever for heating the temperature measurement element. The temperature measurement element and the heating element are superposed with each other on a main face of the cantilever via an electrical insulating layer. As a result, even if the amount of electric energy supplied to the heating element is reduced, it is possible to effectively supply an amount of heat necessary for measurement to the temperature measurement element. Therefore, by minimizing the heat to be supplied to a sample and the cantilever, the respondency of measurement is improved and temperature measurement can be performed with a high degree of accuracy.
Abstract:
Automatic pattern matching and shape measurement are enabled by adjusting a brightness level of a microscope image based on information of a local region of the image so that a magnified image of the local region takes on an appropriate brightness and is not affected by brighter peripheral portions of the image, thereby enabling feature extraction of a desired pattern. By using the inventive method in an energized beam apparatus having a sample stage capable of linear and tilting movement, a series of operations including cross section forming, sample tilting, cross section observation, and pattern recognition, may be performed on an automated basis.
Abstract:
A derived data display adjustment system for a sample analyzer allows user selection of one or more displayed images to be subjected to a derived data calculation process. A derived data user interface is displayed on a display screen in response to user selection of one or more displayed images to enable user selection of a derived data calculation process. A determination is made as to whether or not display of the derived data may be achieved without interfering with other displayed images. If not, a derived data adjustment user interface is displayed to enable a user to select a convenient display location for display of the derived data.
Abstract:
A scanning probe microscope simply and accurately confirms whether or not a sample shape satisfies specified conditions. A pseudo reference image Sref1 comprises a pair of reference line profiles Lref1 and Lref2 arranged apart from each other in parallel. An operator moves and rotates the position of the pseudo reference image Sref1 on a screen so that a sample shape line profile fits between the reference line profiles Lref1 and Lref2 of the pseudo reference image Sref1. If it is possible to fit the line profile of the sample shape between the reference line profiles Lref1 and Lref2, it is determined that the sample shape is in spec, while if it is not possible to fit the line profile of the sample shape between the reference line profiles Lref1 and Lref2, no matter how the pseudo reference image Sref1 is moved and rotated, it is determined that the sample shape is out of spec.
Abstract:
An apparatus determines the thickness and composition of a multi-layered sample comprised of at least a copper layer and a tin-copper alloy plating layer disposed on the copper layer. The sample is irradiated with primary X-rays and an energy-dispersive X-ray detector detects fluorescent X-rays and diffracted X-rays emitted from the sample. An X-ray spectrum of the detected fluorescent X-rays and diffracted X-rays is generated. The concentration of copper in the tin-copper alloy plating layer of the sample is determined utilizing peak intensities of the diffracted X-rays in the X-ray spectrum. The thickness of the tin-copper alloy plating layer of the sample is determined utilizing peak intensities of the fluorescent X-rays in the X-ray spectrum and the determined copper concentration.
Abstract:
The present invention sets out to provide a scanning charged particle microscope equipped with a rapid control function capable of extrapolating an in-focus point from image information for a single frame and an automatic focusing system capable of reliably and precisely carrying out a focusing operation for a horizontal pattern image. The automatic focusing system provided in the scanning charged particle microscope of the present invention is provided with means for changing a focal point each raster scan line, and control means for comparing image information each scanning line and extrapolating focusing positions. The scanning line can then be made to be an inclined scanning line that is a combination of a horizontal component and a vertical component with respect to a chip array on a semiconductor wafer. Further, a method is adopted comprising a first step of reliably taking in a coarse in-focus point and a second step of detecting the in-focus point with a high degree of precision.
Abstract:
In a fluorescent X-ray analysis apparatus, a diffraction X-ray is removable from a sample even if it is formed of a mixture of fine crystals. A movable collimator mechanism capable of detecting only a collimate component of an X-ray optical flux is provided in a secondary X-ray path extending between a sample and an X-ray detector. Spectrum measurement is conducted on the same sample when the collimator mechanism is inserted and removed from the secondary X-ray path.
