The term "4F2" refers to a specific technology node in semiconductor manufacturing. It stands for "Four times the square of the feature size." In other words, it indicates that the area of each feature on the chip (such as transistors or memory cells) is four times smaller than the square of the technology node's feature size.For example, in a 4F2 technology node with a feature size of 10 nanometers (nm), each feature on the chip would have an area four times smaller than (10 nm)², which is 100 square nanometers (nm²). Therefore, the feature size would be around 25 square nanometers (4 x 100 nm² = 25 nm²).This term is commonly used in the context of semiconductor scaling and technology advancements to describe the miniaturization of components on a chip.
