Here's a multi-billion dollar factory where microchips are made. Inside this factory there are hundreds of machines, each costing millions of dollars. Running around the ceiling on tracks you can find plastic containers called "Foops" each carrying a stack of 25 silicon wafers. A single wafer can hold anywhere from 90 to 1000 microchips. For example, GPU chips are rather large and only 90 can fit on a wafer. CPU chips are a little smaller and therefore 230 can fit. And DRAM chips are a lot smaller and 950 can fit across the wafer. Once a wafer is filled with completed microchips, each one is tested, cut out using a laser and then mounted on an interposer and sealed inside. These microchips are used to run all sorts of devices. But have you ever wondered how they are made? Well,
