Samsung integrates heat path block in 2nm FoWLP packaging to challenge TSMC
Thursday, January 22, 2026 at 01:57 AM
Samsung is reportedly utilizing a new Fan-Out Wafer-Level Packaging with integrated Heat Path Block (FoWLP-HPB) for its upcoming Exynos 2600 chip on the 2nm node. This advanced packaging technique is designed to improve thermal management and could potentially attract major clients like Apple, MediaTek, and Qualcomm away from TSMC for 2nm mobile SoC production.
Context
Samsung is intensifying its challenge to TSMC by integrating a proprietary Heat Path Block (HPB) into its 2nm Fan-Out Wafer-Level Packaging. This breakthrough, debuting in the Exynos 2600 processor, utilizes a copper-based heatsink within the package to reduce operating temperatures by approximately 30% and improve thermal resistance by 16%. By addressing the chronic overheating issues that have historically plagued its flagship chips, Samsung aims to position its SF2 process as a superior alternative for the next generation of high-performance AI and smartphone silicon.
The strategic move is designed to lure high-volume clients such as Apple, Qualcomm, and MediaTek, many of whom currently rely on TSMC for leading-edge production. While TSMC remains the market leader, its 2nm wafers are reportedly priced 50% higher than previous generations, and initial capacity is largely monopolized. Samsung expects to begin mass production of these chips in Q4 2025, targeting a commercial launch in the Galaxy S26 series by early 2026. Early test yields for the 2nm process have already reportedly crossed the 30% threshold, with a roadmap toward 50-60% stabilization later this year.
