摘要： A hardness tester includes an image pickup control section, an indentation region extraction section, an indentation apex extraction section and a hardness calculation section. The image pickup control section obtains picked-up image data of a sample's surface. The region extraction section binarizes the image data, determines based on the binarized image data whether an indentation region candidate is extracted, and when determining that the candidate is not extracted, obtains curvature image data, binarizes the curvature image data, erodes and dilates the binarized curvature image data, performs distance transform on the eroded-and-dilated curvature image data, and extracts a closed region corresponding to the indenter's shape using the distance-transformed curvature image data. The apex extraction section extracts an indentation-measurement-use apex based on the closed region. The hardness calculation section calculates the sample's hardness based on the apex.

摘要： In the measurement method, a vibrator (5) of a detection unit (4) is relatively moved against a plate (3) of which surface is flat having predetermined area. The vibrator (5) which is vibrating is moved closer to a surface of an object-to-be-measured (1) which is mounted on the plate (3) until the frequency thereof is varied. A position where the frequency of the vibrator (5) is varied is output as a contact position where the vibrator (5) is contacted to the object-to-be-measured (1). Then, thickness of the object-to-be-measured (1) is measured by comparing the position where the vibrator (5) is contacted to the object-to-be-measured (1) with a surface position of the plate (3).

摘要： A test structure allows one or more deposited thin film layers to be moved such that mechanical properties of the thin film layer or layers may be determined. Methods for characterizing the mechanical properties of the deposited thin film layer include the determination of a transition voltage of the movable thin film layer in the test structure, or the mechanical stiffness of the movable layer, and/or a determination of residual stress within the movable layer. Methods may also include the determination of creep rate or fatigue, as well as the variance in mechanical properties of the movable layer at various temperatures. Test structures used with the testing methods may include structures which interferometrically modulate incident light, enabling electrical or optical determination of the state of the test structures.
