Very Large Scale Integration (VLSI) is a technology used to create integrated circuits by combining thousands to millions of transistors onto a single chip. This process allows for the miniaturization of electronic components, making devices smaller, faster, and more efficient. VLSI is essential in modern electronics, powering everything from smartphones to computers. The development of VLSI has revolutionized the semiconductor industry, enabling complex systems to be built on a single chip. This advancement has led to significant improvements in performance and functionality, facilitating innovations in areas such as artificial intelligence, telecommunications, and consumer electronics.
