Apple is rumored to feature TSMC's 2nm chipset in the iPhone 18 models, though the launch timeline has not yet been revealed.
Apple supply chain analyst Ming-Chi Kuo on Saturday, March 22, 2025, indicated that the A20 chip in the iPhone 18 models will be manufactured with TSMC's 2nm process.
Kuo stated that TSMC's trial production of 2nm chips has now reached yields well above the 60-70% range.

The yield refers to the percentage of functional chips that can be obtained per silicon wafer, a large circular disc containing multiple chips.
The A20 chip will have more substantial performance and power efficiency advancements over the A19 chip in the iPhone 17 models.
Kuo, Pu, and other analysts have suggested that the A19 chip will be manufactured using TSMC's third-generation 3nm process, called N3P.
An overview of current and expected chips:
- A17 Pro chip: 3nm (TSMC's first-generation 3nm process N3B)
- A18 and A18 Pro chips: 3nm (TSMC's second-generation 3nm process N3E)
- A19 and A19 Pro chips: 3nm (TSMC's third-generation 3m process N3P)
- A20 and A20 Pro chips: 2nm (TSMC's first-generation 2nm process N2)
To note, these nanometer sizes are based on TSMC's marketing terms.
