🔍The Intel 486 processor was introduced in 1985 and housed over a million transistors on a small piece of silicon.
🌈The aluminum interconnects in the processor create a vibrant array of colors that defract light into a rainbow.
🔬Using an atomic force microscope, we can see that the aluminum interconnects are about 2 microns tall and 4 microns wide.
💡The surface of the processor is not perfectly flat due to the stacking of multiple layers, creating roughness and waviness.
🔎By using different detectors, we can observe the underlying layers and the materials used, such as silicon dioxide and titanium.
