TSMC’s Capacity Crunch Pushes Fabless Chipmakers Toward Alternatives as Samsung Foundry Gains Momentum

TSMC’s chipmaking lines are feeling the squeeze, and that pressure is starting to ripple across the semiconductor industry. With production capacity increasingly tight and demand still surging from both smartphone giants and high-performance computing leaders, more companies are actively exploring alternative foundry partners. One of the biggest beneficiaries of that shift could be Samsung Foundry.

TSMC remains the world’s most in-demand contract chip manufacturer, capturing a large share of global foundry revenue and producing advanced chips for many of the biggest names in tech. But the same popularity that fuels its dominance is also creating a bottleneck. Major customers spanning mobile chips and AI-focused data center hardware continue to book enormous volumes, leaving less room for smaller or less “priority” fabless chip designers that still need cutting-edge manufacturing.

Recent reporting suggests that as TSMC’s 2nm pricing climbs and order queues grow longer, global tech companies are paying closer attention to Samsung Electronics as a way to diversify supply chains and reduce reliance on a single overbooked supplier. For companies racing to launch new silicon on tight timelines, uncertainty around capacity and delivery windows can be just as important as node performance.

This is where Samsung Foundry steps into a valuable opening. Even if TSMC is known for being highly customer-focused, capacity constraints create risk for designers who can’t afford delays. If a foundry can’t confirm enough wafer starts or cannot meet desired schedules, the safest business move may be to split production across multiple foundries or shift new projects to a supplier with more available capacity.

Samsung is reportedly drawing interest from several major names. Meta is said to be considering Samsung Foundry for its MTIA AI accelerator ASICs, with the SF2 process mentioned as a potential fit depending on Samsung’s progress and readiness. Qualcomm and AMD are also rumored to be evaluating Samsung’s foundry services. While Samsung’s manufacturing improvements over time play a role, a key driver appears to be straightforward: overflow demand from TSMC is pushing more companies to look elsewhere, and Samsung is positioned as a leading alternative for advanced-node production.

Samsung isn’t the only company seeing increased attention. Intel Foundry is also reported to be attracting interest in its upcoming 18A and 14A process technologies, helped in part by its position as a major US-based manufacturer—an appealing factor for American fabless companies looking for domestic or geopolitically diverse production options.

The broader takeaway is clear: the semiconductor industry is increasingly motivated to diversify chip supply. With AI, mobile, and HPC demand accelerating at the same time, relying too heavily on a single manufacturing pipeline can create cost, scheduling, and strategic risks. If TSMC’s capacity remains constrained and advanced-node prices continue rising, Samsung Foundry and Intel Foundry could see stronger external adoption as more chip designers spread their bets and secure manufacturing capacity wherever it’s available.
