Samsung’s Advanced Packaging Lag Clouds AI Chip Comeback, Falling Behind TSMC and Intel

digitimes Taiwan

Overview

Despite efforts in HBM and foundry services, Samsung Electronics’ lagging advanced packaging capabilities remain a significant weakness in the AI chip supply chain. Industry sources and Korean media reports indicate Samsung lags behind TSMC and Intel in this critical area, impacting its ability to secure a larger share of the burgeoning AI chip market. The increasing importance of advanced packaging for AI chip performance exacerbates this challenge.

In Depth

Key Findings

Samsung Electronics, while striving to rebound in high-bandwidth memory (HBM) and foundry services, faces a major hurdle: its lag in advanced packaging capabilities within the AI chip supply chain. Reports from industry insiders and Korean media highlight that Samsung trails TSMC and Intel in this crucial area.

Technical and Business Details

• The performance of AI chips relies heavily not only on advanced process nodes but also on advanced packaging technologies that integrate multiple chips (e.g., GPUs, HBM, interposers) in high density. While Samsung boasts strengths in HBM, its supply capacity and technological maturity in 2.5D/3D packaging solutions like CoWoS are perceived as inferior to competitors.
• Analysts at DigiTimes Research suggest that Samsung’s advanced packaging capacity may not be adequately meeting the demands of major AI chip customers such as NVIDIA. This potentially places Samsung at a disadvantage when offering comprehensive solutions that combine its HBM products with its foundry services.
• Intel is aggressively advancing its proprietary packaging technologies like Foveros and EMIB, while TSMC dominates the market with CoWoS. In contrast, Samsung requires further investment and time to build its own robust ecosystem and mass production capabilities in advanced packaging.
• Although HBM supply capacity is crucial in the AI chip market, it is essential that the packaging technology integrating HBM does not become a bottleneck, allowing HBM performance to be fully realized.

Background & Context

The AI revolution is shifting the focal point of competition in the semiconductor industry. Where traditional foundry competition centered on fine process nodes, advanced packaging has become the new battleground, dictating AI chip performance and time-to-market. Samsung, a global leader in DRAM and NAND flash memory and with a foundry business, finds its strategic position in the AI chip market threatened by this relative delay in advanced packaging. This represents a critical challenge for the company to assert leadership in the AI era.

Strategic Significance & Outlook

Samsung recognizes strengthening its advanced packaging capabilities as a top priority and is expected to accelerate massive investments and technological development. This will likely include R&D for new packaging technologies, expansion of production facilities, and establishment of supply chain partnerships. If Samsung successfully bridges this gap and stands alongside TSMC and Intel, competition in the AI chip market will further intensify, fostering accelerated innovation. However, for now, this disparity in packaging capabilities is likely to cloud Samsung’s growth prospects in the AI chip market.
