A "Process Node" refers to a specific manufacturing technology used in the production of semiconductor devices, such as integrated circuits. It is defined by the smallest half-pitch of contactable features that can be created on a chip, typically measured in nanometers (nm). Smaller process nodes generally allow for more transistors to be packed into a given area, leading to improved performance and energy efficiency. As technology advances, companies like Intel and TSMC develop smaller process nodes to enhance the capabilities of electronic devices. For example, moving from a 14nm process node to a 7nm node can significantly increase processing power while reducing power consumption, benefiting applications in areas like artificial intelligence and mobile computing.
