apple’s iPhone 18 is poised to launch a revolutionary A20 chip, marking a significant shift in mobile technology with advanced packaging. This redesign will enhance performance and efficiency, promising a leap forward in the next generation of iPhones. news Directory 3 reports that the A20 chip, expected in the iPhone 18 Pro, Pro Max, and perhaps the Fold, will leverage Wafer-Level Multi-Chip Module (WMCM) packaging. This innovative method integrates components directly at the wafer level, boosting thermal and signal integrity. The shift to a 2nm process also means a smaller, more power-efficient design. This groundbreaking technology, previously reserved for data centers, aims to transform mobile device capabilities. discover what’s next for Apple’s cutting-edge silicon innovations.
Apple’s iPhone 18 to Feature Redesigned A20 Chip
Apple is set to revamp its chip design for the iPhone 18, potentially marking the first use of advanced multi-chip packaging in its mobile devices. This move aims to enhance performance and efficiency in the next generation of iPhones.
According to Jeff Pu, an analyst at GF Securities, the iPhone 18 Pro, iPhone 18 Pro Max, and the rumored iPhone 18 fold are expected to feature Apple’s A20 chip. This chip will be built using TSMC‘s second-generation 2nm process (N2).
The A20 chip will use Wafer-Level Multi-Chip Module (WMCM) packaging. This technology integrates components like the SoC and DRAM directly at the wafer level before the chips are separated. This method connects the dies without needing an interposer or substrate, improving thermal and signal integrity.
The next-generation chip will be smaller and more power-efficient, thanks to the N2 process. The closer proximity to onboard memory will improve performance and potentially lower power consumption for AI processing and high-end gaming.
TSMC is reportedly building a dedicated WMCM production line and expects to ramp up production by 2027.
TSMC will establish a dedicated WMCM production line at its AP7, leveraging equipment and process similar to CoWoS-L without on-substrate.We see TSMC is preparing capacity of up to 50KPM by end of 2026 and estimate the capacity to reach 110-120KPM by end-2027, due to the increase in adoption.
This new chip design represents a meaningful advancement for Apple, similar to its early adoption of 3nm technology. It also signals a broader trend in the mobile market, bringing technologies previously used in data centers and AI accelerators to smartphones.
What’s next
The iPhone 18 Fold may serve as a testbed for this next-generation silicon packaging,indicating Apple’s intention to use its most innovative hardware for its foldable devices.
