This image shows the result of TKD (Transmission Kikuchi Diffraction) crystal orientation analysis of the Cu electric wiring, in which fine grains of the crystal are the pseudo-colored as the color crystal map. This technique using transmission electrons enables us to see the orientation map of the tens nm grain which could not be visualized by the conventional method with backscattered electrons. The grain orientation map is like the stained glass made of the fine crystals.
