The main development is the transition to “nanostructures” (nanosheets) instead of traditional FinFET technology. This change increased efficiency by 15% and reduced energy consumption by 30%. As a result, the efficiency of the new process increased significantly.
Additionally, transistor density has increased by 15% thanks to N2 NanoFlex technology and the use of full-area transistors (GAA). This allows more logic elements to be placed in a smaller space, which improves overall performance.
With the transition to 2nm technology, TSMC has also greatly improved control over current flow, allowing manufacturers to fine-tune parameters according to needs.
However, new technologies will also increase production costs. The cost of a semiconductor wafer based on 2nm technology can range from $25,000 to $30,000; This is 10% more expensive than analogues with 3nm technology.
