Silicon fabrication is the process of creating integrated circuits and microchips from silicon, a widely used semiconductor material. This process involves several steps, including doping, etching, and layering, to build complex electronic components on a silicon wafer. The goal is to create tiny structures that can control electrical signals. The fabrication process requires a cleanroom environment to prevent contamination, as even microscopic particles can affect the performance of the final product. Advanced techniques, such as photolithography, are used to transfer circuit designs onto the silicon wafer, enabling the production of modern electronic devices like smartphones and computers.
