Color photos rarely appear on our website. After all, the electron microscope differs from the light microscope. This time, however, we will probably surprise you with the number of colors. One of our apprentices wanted to check the quality of the copper layer that she used to cover the molybdenum wire from the previous post. To do so, she made a cross-section of the wire using our XePFIB microscope and analyzed the elemental composition using the EDS (Energy-Dispersive X-ray Spectroscopy) method. In this way she confirmed that copper plating was successful and that the surface was covered with a continuous layer of metal. EDS elemental analysis is a great tool to verify the production processes of, for example, thin layers, or to determine the elements arrangement in a given sample volume. More information about the test is available on our website. Enjoy reading!
