Semiconductor nodes, also known as process nodes or simply "nodes," refer to the size of the transistors and other key components on a semiconductor chip. These nodes represent the smallest dimensions that can be reliably manufactured using a specific process technology. In essence, they define the building blocks of our digital devices, from smartphones and laptops to data centers and beyond.

If we broadly cover the different type of transistors design type based on manufacturing architecture,there are three major types namely Planer, FinFETs & GAA. Planar transistors are the older and simpler technology, they are less suitable for advanced semiconductor nodes due to limitations in scalability and power efficiency. FinFETs and GAA transistors represent newer 3D transistor designs that offer better performance and scalability. FinFETs are currently widely used, while GAA transistors are considered the next step in transistor technology, offering even greater control and efficiency, albeit with more complex manufacturing challenges

When we talk about Planer type, technology node actually refer to the physical dimensions or minimum feature size of the transistors or gate length. Once we shifted from Planer to new manufacturing architecture of transistors called FinFET & GAA, technology node no longer followed the "actual gate length" and has no physical significance and is just a marketing number. It has an analogical significance to the performance and efficiency in comparison to the previous predecessors.
