Abstract

PURPOSE:To eliminate an influence due to the electromagnetic waves, of an apparatus at the circumference, which cause the noise of an AE signal when the contact force and the adhesion force of a thin film are measured. CONSTITUTION:All measuring parts 1 to 8 in a measuring apparatus are covered with a cover 7 which is composed of a conductive magnetic substance, e.g. iron or ferrite. Thereby, it is possible to prevent an indenter 4 detecting an AE signal due to the breakdown of a thin film from being affected by the electromagnetic waves of a personal computer 10 and of a CRT display 11 at the circumference and by the electromagnetic waves of an adjacent apparatus as noises.

Alternatively, an indenter 4 made of a PZT-AE transducer, whose tip is processed by ruby, ceramic, cemented carbide, etc. and bonded, is attached to the tip of a piezoelectric actuator that is a driver 5, and pushes and deforms the test piece 1. At the same time, the AE signal associated with the destruction inside the substrate or the thin film or at the interface between the substrate and the thin film is detected. The displacement meter 6 attached to the indenter 4 uses a light intensity type displacement meter, and measures the amount of pushing of the indenter 4 with respect to the test piece 1. The peeling of the film is detected by measuring the number and amplitude of AE signals generated, and the adhesive force is obtained from the pushing load and the pushing depth at that time.

In this conventional thin film mechanical property measuring apparatus, a personal computer 10 and a CRT display 11 are provided for automatic control of the measuring operation.
However, there is a problem in that the AE signal detected by the indenter is mixed with noise due to the electromagnetic waves of these peripheral devices and the AE signal generated by the peeling phenomenon cannot be accurately measured. In addition, the electromagnetic waves generated from equipment outside the device vibrates the metal such as iron inside and also mixes in the AE signal for detecting the peeling phenomenon, so that the peeling phenomenon cannot be accurately detected. There was a point.
