iPhone 18 to Feature Foldables, A20 Chip with TSMC’s N2 Process, and Advanced Packaging

Apple’s 2026 iPhone lineup is shaping up to be one of the most technically ambitious yet. According to a new investor note from GF Securities analyst Jeff Pu, the iPhone 18 series will feature a host of next-gen innovations—ranging from foldable designs to cutting-edge chip technology.

A20 Chipset to Use TSMC’s N2 Process

At the heart of the iPhone 18 Pro, Pro Max, and rumored iPhone 18 Fold will be Apple’s new A20 chip, reportedly manufactured using TSMC’s advanced 2nm (N2) process. This leap promises better performance and power efficiency, keeping Apple ahead in the mobile silicon race. TSMC’s N2 node is expected to enter volume production by late 2025.

WMCM Packaging: The Next Step in Chip Integration

In a first for Apple, the A20 will use a Wafer-Level Multi-Chip Module (WMCM) approach—where components like the SoC and DRAM are assembled together on the wafer itself. This method, enhanced by Redistributed Layer (RDL) technology, improves signal integrity and thermal performance compared to traditional interposer-based packaging.

TSMC is reportedly ramping up a dedicated WMCM line at its AP7 fab, with monthly capacity expected to reach 50,000 wafers by late 2026 and up to 120,000 wafers by 2027.

Foldables, Redesigns, and Memory Upgrades

In addition to its first foldable iPhones, the iPhone 18 series could bring:

• Under-display Face ID and a relocated front camera for Pro models

• A redesigned chassis across the premium lineup

• 6-channel LPDDR5X RAM for higher memory bandwidth

• Samsung’s M16 OLED material set, offering improved brightness and efficiency

Possible Staggered Launch

Rumors also suggest Apple might stagger the iPhone 18 release—with Pro and Fold models arriving in fall 2026, and standard variants following in spring 2027. This would mark a notable shift in Apple’s traditional launch cadence.

Bottom Line:
Apple is gearing up for a transformative iPhone cycle in 2026, with foldables, 2nm A20 chips, and revolutionary chip packaging all in play. If the reports hold true, iPhone 18 could redefine Apple’s hardware roadmap—and possibly the entire smartphone market.
