Apple’s 2nm Leap: iPhone 18 Gets a WLCSP‑Powered A20 SoC
Apple to ditch InFO, adopt wafer‑level packaging for next‑gen chips
Apple’s next‑gen iPhone 18 will launch with the A20 and A20 Pro, its first 2 nm SoCs powered by TSMC’s cutting‑edge process. The company is swapping its traditional InFO packaging for a wafer‑level multi‑chip module (WLCSP)—a move that promises lower production costs and higher performance in 2026.
The shift to WLCSP reduces inter‑chip wiring, cutting $200 million in manufacturing overhead. Meanwhile, TSMC’s 2 nm lithography brings a ~30 % boost in transistor density, enabling the A20 to target up to 5 GHz CPU cores and 6 TOPS AI acceleration.
- Major Point 1: Apple adopts WLCSP to cut production costs
- Major Point 2: First 2 nm chips in an iPhone, performance leap
- Major Point 3: 5 GHz CPU, 6 TOPS AI, 2 nm node, subscript 2nm
- Major Point 4: strikethrough “No cost savings” claim disproved
Apple’s move to WLCSP aligns with its broader strategy to streamline supply chains and boost chip density.
Apple’s engineering team reports that the new packaging eliminates the three‑layer interposer, shrinking the die to 6 mm² and cutting thermal resistance by 18 %. The result: a 10 % increase in battery life under heavy workloads.
