Semiconductor chips, often called microchips or integrated circuits (ICs), are tiny electronic components made primarily from semiconductor materials like silicon. These materials have electrical properties that allow them to act as both conductors and insulators, depending on how they’re treated. A semiconductor chip contains millions or even billions of microscopic electronic parts such as transistors, diodes, and resistors, all working together to process and store information. They are the foundation of modern electronics and are used in almost every device — from smartphones, computers, and cars to medical equipment, industrial machines, and home appliances.
