The Evolution of Microchips and the Race to 3nm Technology

Have you ever heard of Moore's Law? It's a prediction made by Intel co-founder Gordon Moore. He predicted that the number of transistors in a microchip would double every two years, and the cost would decrease. This has held for the past few decades. In 1968, a single transistor occupied a space of 20 micrometres in a chip, and now, in 2025, we are talking about 3 and 2 nanometers.

Our IC manufacturing technology has greatly improved over this time, with new technology nodes being implemented each year. This increase in the number of transistors in a chip also boosts its computing power, while significantly reducing its cost.

A technology node is a scale that represents the unit length and width of a transistor in a microchip.

Current Standard: 

Samsung is now developing 3nm chips, TSMC is also on 3nm, and Intel is on the same page. Technically, the technology still requires more refining and error correction due to the ultrathin 3-nanometer transistor walls, but the chipsets are already on the market.
