In the realm of electronics, feature sizes are crucial for the development of integrated circuits and transistors. Smaller feature sizes allow for more components to be packed into a smaller area, leading to more powerful and efficient devices. The Mooreâs Law, which predicts the doubling of transistors on a chip approximately every two years, is driven by advances in reducing feature sizes. However, as feature sizes approach the atomic scale, new physical challenges and limitations arise, necessitating innovative approaches and materials.
