The process was a high-stakes dance called . First, a light-sensitive liquid—the photoresist—was spun onto the wafer, coating it in a perfect, glassy film. Then came the stencil, or "mask." It held the blueprint of a labyrinth so complex that if you enlarged it, it would look like a map of every street in the world overlapping ten times.
Finally, the . A diamond saw screamed through the silicon, separating the wafer into hundreds of individual chips, each no bigger than a fingernail. Chip Manufacturing - How are Microchips made? | Infineon
The story of a microchip doesn’t start with gold or lasers. It starts with . The process was a high-stakes dance called
Days passed. Layer upon layer of copper "highways" were laid down to connect the transistors. By the end, the wafer looked like a shimmering city seen from orbit. Finally, the
