Chip Manufacturing - How Are Microchips Made? | Infineon ◆

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."

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. Chip Manufacturing - How are Microchips made? | Infineon

The story of a microchip doesn’t start with gold or lasers. It starts with . Silicon Valley wasn't just a place for Silas;

But a skeleton has no soul. To give the chip "life," Silas moved to . He watched the monitors as machines bombarded the silicon with specific atoms, turning bits of the wafer into conductors or insulators. This created the transistors—the tiny switches that would soon be snapping on and off billions of times a second. With a chemical wash, the soft parts vanished,

"Time for the coat," he muttered, adjusting his clean-room suit.
