💻 How Are Microchips Made?

Microchips are made by building tiny cities on a very small piece of glass, like stacking blocks to make a tower.

Imagine you have a special kind of glass, it's super clean and smooth, almost like the surface of a lake. This is your starting point: a wafer.

First, engineers use special machines that act like really precise painters. They draw tiny lines on the glass, just like you might draw with crayons, but these are super small and very accurate.

Then they add layers, kind of like putting on a coat of paint, except each layer is a different material. These layers help create the roads and buildings in the microchip’s city.

After all the layers are added, engineers use tiny tools to cut out parts of the glass, just like you might cut shapes out of paper. This creates the paths that electricity can follow, it's how the chip works!

At the end, the big piece of glass is cut into little pieces, each one becoming a microchip, ready to be used in your toys, phones, or even your smartwatch!
