Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
