A motorized and automated WITec Alpha 300 Confocal Raman microscope was used to analyze the composition of the thicker polymer layers and the thinner bonding materials present between each layer. The Raman microscope is ideally suited for this type of analysis as it uses an automated reflectance mode that can directly analyze and chemically map the ion milled cross section while resolving chemical phases 200 nanometers in size.
