This grayscale image is a cross-sectional view of a semiconductor device, likely a DRAM or similar memory structure. It shows multiple layers and components built up on a substrate. The bottom layer is labelled 'substrate', followed by 'transistors', 'Co', 'Cu + Co', and 'Cu'. Above the 'Cu' layer is an 'insulator' with a geometric shape. The image appears to be a microchip or integrated circuit, captured using microscopy techniques.
