Introduction
In a strategic move poised to disrupt the dominance of Apple in the high-end smartphone market, Google is gearing up to switch to TSMC’s fan-out (InFO) packaging technology in 2025.
This significant transition involves Google’s self-developed Tensor chips, which will be manufactured using TSMC’s advanced 3nm process and integrated with InFO packaging.
By integrating components directly onto the package substrate, it reduces the overall thickness of the chip. This is particularly crucial for smartphones where space is at a premium.
This shift is expected to substantially reduce chip thickness and enhance energy efficiency, making it a pivotal development in the competitive AI-powered smartphone market.

Google’s Tensor Chips to Leverage TSMC’s 3nm Process
According to reports from China’s Business Times, Google’s forthcoming Pixel 10 series, set to release next year, will feature the Tensor G5 chip produced using TSMC’s 3nm process.
This cutting-edge technology will be complemented by InFO packaging, an innovation that allows for a more compact and efficient chip design.
The adoption of this technology signifies Google’s commitment to pushing the boundaries of smartphone performance and energy efficiency.
TSMC’s Fan-out (InFO) Packaging Technology
TSMC’s InFO (Integrated Fan-Out) packaging is a revolutionary method of connecting the tiny components within a chip to the outside world. It involves spreading out (or fanning out) the chip’s connections across a flat surface, rather than using the traditional bulky method.
What makes it special?
- Thinness: InFO packages are significantly thinner than traditional ones, allowing for slimmer devices like smartphones.
- Efficiency: By reducing the distance between components, InFO improves performance and energy efficiency.
- Flexibility: It can accommodate various chip designs and configurations, making it versatile for different applications.
- Cost-effective: InFO can potentially reduce manufacturing costs due to its simpler structure.
Why is it special for Google?
For a company like Google, focused on developing cutting-edge smartphones with powerful AI capabilities, InFO packaging offers several advantages:
- Improved AI performance: By allowing for closer integration of components, InFO can enhance the speed and efficiency of AI calculations.
- Longer battery life: The thinner profile of InFO packages leaves more room for a larger battery, extending device usage time.
- Enhanced camera capabilities: By enabling faster data transfer between the image sensor and the processor, InFO can contribute to better image quality and faster camera performance.
- Thinner and lighter devices: In line with Google’s design philosophy, InFO can help create more sleek and portable smartphones.
Essentially, InFO packaging aligns perfectly with Google’s goal of creating high-performance, energy-efficient, and stylish smartphones.
The Advantages of TSMC’s InFO Packaging
TSMC’s InFO packaging technology is designed to address the growing demand for thinner and more energy-efficient chips in high-end smartphones.
By integrating fan-out technology, TSMC can create a package that significantly reduces the overall thickness of the chip while maintaining or even enhancing performance.
This is particularly crucial for AI-driven applications, where processing power and energy efficiency are paramount.
