Discover how TSMC’s new supplier of advanced packaging materials boosts Apple’s 2026 iPhone and Mac processor performance with cutting-edge chip technology.
Industry expert Ming Chi Kuo has again made waves with what promises to be one of the most anticipated product lineups for Apple next year, 2026. He disclosed that Apple’s chief chip supplier, TSMC, has collaborated with a new source of high-end packaging materials for the iPhone 2026 and Mac processors.
This strategic collaboration has the potential to reshape Apple chip performance, improve thermal efficiency, and automate production across devices. This is a significant change that could impact not just device capabilities but also the semiconductor market overall, investors, tech buffs, and Apple aficionados say.
This blog will cover supplier information, the development of chip packaging technology, its effects on Apple devices, and the reasons this is significant for the industry as a whole.
1. Ming‑Chi Kuo: Apple’s Supply Chain Expert
Ming-Chi Kuo is known to provide precise details of Apple’s supply chain and product roadmaps. Months, even years prior to time, his predictions tend to mark forthcoming hardware transitions. Kuo provides an insight into Apple’s dwindling 2026 iPhone and Mac processor plans by announcing TSMC’s latest source of cutting-edge packaging components.
Knowledge of these shifts in the supply chain is important because leading markets directly influence chip performance, power conservation, and device ability. Apple in particular is an example, with Apple continuously pushing the limits of design and computation.
2. Eternal Materials: Apple’s New Supplier
Eternal Materials, the recently hired supplier, will provide essential components for TSMC’s cutting-edge packaging technology. The company is set to supply LMC for the M5 chips in Macs and MUF for Apple’s A20 chips in the 2026 iPhones. This collaboration marks a significant step in Apple’s next-generation hardware development.
These high-margin materials were previously under the control of Japanese companies, but the arrival of Eternal Materials marks a significant shift in the market. Intel is now a major player in Apple’s upcoming chip production thanks to its partnership with TSMC, which could affect design, performance, and manufacturing scale.
3. Advanced Packaging: From InFO to WMCM
3.1 Technologies for Packaging
The current A20 and M5 chips from Apple will be replaced by Transition Wafer-Level Multi-Chip Module (WMCM) technology.
Outdated Integrated Fan-Out (InFO) processes have been replaced by a single process that combines molding and underfill.
The advantages include
- enhanced chiplet integration for better performance
- Increased heat control and power efficiency
- Flexibility in upcoming replacements and chip designs
Apple’s strict requirements for small and power-efficient chip design will be met while Mac processor performance is enhanced by the incorporation of LMC into CoWoS packaging.

3.2 Benefits of WMCM and LMC
Apple is reaping several significant benefits from the use of WMCM and LMC materials:
faster processing, especially for tasks involving AI, graphics, and machine learning
- Reduced heat emissions and power consumption
- ability to improve M5 chip performance for Macs and create multiple A20 chip models for iPhones
- These developments demonstrate how innovative packaging materials directly impact device experience and allow Apple to create more potent and effective products.
4. Implications for Apple’s 2026 iPhones and Macs
By combining all of this, Apple will be able to: Deliver iPhones that are faster and use less energy.
- Use more robust and dense chips to increase Mac performance
- Unlock potential new features such as enhanced AI processing, graphics performance, and memory management.
This development shows how committed Apple is to offering cutting-edge products that meet the growing demands of customers worldwide.

5. Industry Impact
5.1 Changing Supplier Dynamics
With Eternal, Apple and TSMC are shaking the traditional hold of Japanese suppliers on advanced packaging materials. The act has larger ramifications:
- It fortifies Apple’s supply chain against possible geopolitical threats
- Spurs innovation in Taiwanese suppliers and elsewhere
- Possibly boosts suppliers such as Eternal’s profit margins
5.2 Future Growth
The implementation of WMCM and LMC content is likely to make a major contribution to Eternal’s top line. Over the long term, the technologies can allow Apple to ramp up CoWoS and CoPoS packaging offerings across successive chip generations, further entrenching its performance lead in both iPhones and Macs.
6. Why You Should Care
This innovation isn’t merely about chips; it’s about Apple’s future devices. With TSMC’s new supplier and cutting-edge packaging methods, Apple is set to provide:
Faster, longer battery life devices
- Increased device configuration and performance level options
- Strengthened supply chain, lowering risk and allowing innovation
Investors, technophiles, and Apple enthusiasts alike would do well to pay attention to these changes, as they speak to how Apple will continue to compete in the future.
