What is 22NM technology in vlsi?

22NM technology in VLSI (Very Large Scale Integration) refers to a semiconductor manufacturing process that allows the fabrication of transistors with dimensions of approximately 22 nanometers. This scale enables the integration of billions of transistors on a single chip, improving performance, energy efficiency, and overall functionality. The 22NM process often employs advanced techniques such as FinFET (Fin Field-Effect Transistor) architecture, which helps overcome issues like leakage current and scaling limitations found in previous generations. This technology is widely used in modern processors and high-performance computing applications.
