Description	The paper describes a new method for testing of thin layers, so-called microcompression test. As an example determination of Al thin film properties deposited on Si substrate is introduced in the paper. Microcompression combines the sample preparation with the use of focused ion beam (FIB) with a compression test carried out using nanoindenter. Cylindrical specimens (pillars) were prepared in Al film using FIB. The typical diameter of pillars was about 1.3 μm and their height was about 2 μm. The results depend on crystallographic orientation of pillar. Stress-strain curves of the thin film were obtained. Experimentally measured data on pillars needs correction to obtain undistorted material properties of Al thin film. A necessary correction using finite element modeling is suggested in the paper. The paper contributes to a better characterization of very thin surface layers and determination of their mechanical properties.
