Samsung may drop FOWLP for Exynos 2700 chip

🔑 Enhanced Key Takeaways

•Samsung is exploring a Side-by-Side (SbS) packaging design as an alternative to FOWLP for the Exynos 2700, which involves placing the application processor and memory chips next to each other rather than stacking them vertically.
•The Exynos 2600, used in the Galaxy S26 series, already incorporates a Heat Pass Block (HPB) technology, a copper-based heat spreading structure, which is expected to be retained in the Exynos 2700 even if FOWLP is dropped.
•The potential shift away from FOWLP is primarily driven by high manufacturing complexity, significant cost burden, and associated yield risks, particularly for chips produced in more limited volumes.
•The Exynos 2700 is slated for mass production in the second half of 2026, utilizing Samsung Foundry's second-generation 2nm Gate-All-Around (GAA) fabrication process (SF2P), with a goal to power approximately 50% of the upcoming Galaxy S27 devices.
•There are conflicting reports, with some sources suggesting Samsung may ultimately retain FOWLP for the Exynos 2700 to ensure competitive performance against rivals like Qualcomm and MediaTek, implying the initial reports might have been strategic leaks.

🛠️ Technical Deep Dive

FOWLP (Fan-Out Wafer-Level Packaging):
- A high-density advanced packaging technology where electrical connections and molding are completed at the wafer stage.
- Places electrical connections (Redistribution Layers - RDLs) outside the die area, allowing for more I/O pins and a smaller, thinner package.
- Integrates the chip on a silicon wafer substrate rather than a Printed Circuit Board (PCB), which significantly improves heat dissipation.
- Reduces parasitic effects and shortens circuit paths, leading to faster signal transmission and reduced power consumption.
- Can reduce thermal resistance by up to 16% and make chips 40% smaller.
- Eliminates the need for a package substrate and wire bonding, potentially reducing production costs by up to 30% at scale.
Side-by-Side (SbS) Packaging Design (Proposed Alternative):
- Places the application processor (AP) and memory chips (DRAM) adjacent to one another on the substrate, rather than stacking them vertically.
- Increases the horizontal surface area of the package, which can help improve heat dissipation and overall efficiency.
- Can make the chip package vertically thinner, which is beneficial for slim smartphones.
Heat Pass Block (HPB) Technology:
- An additional thermal enhancement technology that embeds a copper-based heat spreading structure within the package-on-package (PoP) architecture.
- Improves heat transfer between the processor and stacked DRAM.
- In an SbS configuration, the HPB would be placed on top of both the processor and DRAM to quickly dissipate heat from both components.

🔮 Future ImplicationsAI analysis grounded in cited sources

Samsung will likely prioritize cost-efficiency and yield stability in its future Exynos chip development.

The re-evaluation of FOWLP for the Exynos 2700 due to high manufacturing costs and yield risks indicates a strategic shift towards more profitable production methods, even if it means exploring alternative packaging.

The Exynos 2700, regardless of FOWLP adoption, will aim for enhanced AI performance and a larger market share within Samsung's own devices.

Samsung has publicly stated its intention to expand market share with the Exynos 2700 by offering enhanced AI performance and aims to power around 50% of Galaxy S27 devices.

Samsung's packaging strategy for future Exynos chips may become more flexible, adapting to specific product needs and market conditions.

The consideration of both FOWLP and SbS, along with the continued use of HPB, suggests Samsung is willing to combine or switch packaging technologies to balance performance, cost, and form factor requirements.
