Taiwan Semiconductor Manufacturing Co. has developed a new chip packaging technology called CoPoS, aimed at competing with Intel in the fast-growing market for artificial intelligence processors. The innovation could reshape how AI chips are produced and potentially bring down costs, according to information released by the company.
What CoPoS brings to AI chips
The technology — whose name likely stems from a typo for CoWoS (Chip-on-Wafer-on-Substrate) or a similar acronym — focuses on packaging, the process of connecting multiple chips together in a single module. For AI workloads, which demand massive parallel processing, packaging is as critical as the chip design itself. TSMC’s CoPoS is designed to improve performance and efficiency while reducing manufacturing complexity.
Lower costs would be a direct benefit. AI chip packaging today is expensive, often accounting for a significant portion of the total chip cost. By streamlining the process, TSMC could make advanced AI hardware more accessible to a wider range of companies, not just the largest cloud providers.
Why Intel is the target
Intel has been pushing its own advanced packaging technologies, such as EMIB and Foveros, as part of a broader strategy to win back chipmaking business from TSMC. The U.S. chipmaker has positioned itself as a foundry that can offer both leading-edge logic and cutting-edge packaging under one roof. TSMC’s CoPoS is a direct response — a way to keep its own customers from defecting to Intel’s foundry services.
The competition is heating up as demand for AI chips explodes. Nvidia, AMD, and a growing list of startups all rely on TSMC for their most advanced processors. If Intel can match or beat TSMC on packaging, it could peel away some of that business. TSMC isn’t waiting to find out.
What’s known — and what isn’t
TSMC has not disclosed technical details of CoPoS, such as the exact interconnect density or power efficiency gains. The company also hasn’t said which customers might be first to use the technology. Industry watchers expect more information to emerge at upcoming industry conferences or during TSMC’s quarterly earnings calls.
One thing is clear: the packaging race is no longer a sideshow. It’s a central battleground in the semiconductor industry, and TSMC just fired a new salvo.
