In this article, we present a study to measure average thickness and as well as the thickness uniformity of the ultra-thin AlO_x barrier layer by combined RBS and conducting atomic force microscopy(C-AFM). RBS in tilted angle geometry was used to determine the average thickness on a macroscopic scale. By carefully analyzing the variation of energy width of Al spectra with tilt angle, the average thickness of AlO_x layers has been quantitatively determined. The thickness and thickness uniformity on a microscopic scale was measured by C-AFM. The errors of both techniques will also be discussed.
