The chips that power our smartphones, laptops, and other electronic devices are miracles of modern technology. But have you ever wondered how they are made? The process of making chips is incredibly complex and involves multiple steps. It all starts with a silicon wafer, a thin disk of purified silicon. This wafer serves as the base for the microprocessor, which will be etched onto its surface. To create the microprocessor, a series of photolithography steps are performed, involving the use o...
