Drawing the chip making processfrom @itsmarceliina

You're only able to watch this video because this pretty rock was turned into a computer chip, and here's how it happens. The journey starts with quartz, which contains silicon, the foundation of computer chips. Silicon works because it's a semiconductor, so its conductivity can be precisely controlled. Although it's the second most abundant element in Earth's crust, it's usually chemically handcuffed to oxygen. So quartz is heated with carbon at around 2,000 degrees Celsius to free the silicon, then put through a much more intensive purification process until it reaches around 99.99999999 or 11 nines percent purity, the level needed for chip making. The purified silicon is then melted in a crucible and a tiny seed crystal is dipped into it and slowly pulled upward while rotating. Over a few days, silicon solidifies around the seed until it forms one massive crystal called an ingot, which is then sliced into wafers raging in size typically up to about 12 inches across and less than a millimeter thick, then polish until they're almost perfectly flat and mirror like. Those blank wafers then spend several weeks inside semiconductor fabs where the tier
