A blast of deep ultraviolet light shot through the mask. Where the light hit the wafer, the "batter" hardened; where it was blocked, it remained soft. With a chemical wash, the soft parts vanished, leaving behind the skeletal remains of a circuit.
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
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. A blast of deep ultraviolet light shot through the mask
Silicon Valley wasn't just a place for Silas; it was a kitchen, and he was the master chef of the microscopic. He stood in the "Yellow Room" of the Infineon plant, bathed in amber light that prevented rogue UV rays from spoiling the "batter." Finally, the
Silas watched the latest batch of silicon ingots—massive, shimmering cylinders of 99.9999% pure glass—being sliced into wafers as thin as a playing card. These were the canvases. To Silas, they looked like mirrors reflecting a digital future.
