The TSMC Nanjing 12-inch wafer fabrication plant has officially entered mass production, delivering its first batch of 16nm-class advanced process wafers. This milestone marks a significant leap in China’s semiconductor manufacturing capabilities and underscores the growing influence of cryptocurrency mining demand on global chip production dynamics.
Remarkably, the facility achieved full-scale output in just 20 months—from groundbreaking to shipment—an impressive feat that highlights TSMC’s operational efficiency and strategic commitment to expanding its mainland China footprint. The first major recipient of these cutting-edge chips is Bitmain, the world-leading manufacturer of cryptocurrency mining hardware.
This development positions the Nanjing plant as China’s first facility capable of producing 16nm-class wafers at scale, reinforcing TSMC’s dominance in advanced semiconductor manufacturing while intensifying the technological rivalry with Samsung in the high-performance computing (HPC) and crypto-mining sectors.
Semiconductor Hub: The Rise of Nanjing
Nanjing, historically renowned as an ancient capital of China, is undergoing a transformative shift into a modern semiconductor powerhouse. Since 2015, the city has strategically attracted leading tech firms, most notably TSMC and Tsinghua Unigroup, catalyzing the growth of a comprehensive semiconductor ecosystem.
Today, Nanjing hosts a fully integrated supply chain encompassing chip design, fabrication, and packaging. This vertical integration has created a robust industrial cluster, drawing both established corporations and innovative startups focused on advancing domestic semiconductor capabilities.
China's appetite for semiconductors is immense. In 2017 alone, the country accounted for over $250 billion of the global $400 billion semiconductor purchase volume—more than 60% of total demand. With such massive domestic consumption, localizing production has become a national priority.

The TSMC Nanjing plant plays a crucial role in this strategy by reducing reliance on foreign-sourced chips and accelerating progress toward higher "localization" rates in critical technology sectors. As domestic demand continues to grow, facilities like this will be instrumental in closing the gap between China’s chip needs and self-sufficiency.
The Battle for Mining Chip Supremacy
Cryptocurrency mining has emerged as a key growth driver in the semiconductor industry. Specialized Application-Specific Integrated Circuit (ASIC) chips are now at the heart of this competitive landscape, fueling demand for advanced process nodes like 16nm and below.
TSMC has positioned itself as the go-to foundry for high-performance computing applications—including AI, deep learning, and blockchain mining—earning the moniker “everyone’s foundry.” While the company maintains a cautious public stance on cryptocurrency volatility, it cannot ignore the tangible revenue generated from mining-related orders.
In 2017, HPC-related business accounted for about 20% of TSMC’s total revenue. During recent earnings calls, executives projected this figure could rise to 25% in 2025, driven largely by continued demand for ASICs and graphics processors used in data centers and mining farms.
Analysts estimate that HPC revenue could grow between 37.5% and 43.75% year-on-year, suggesting that TSMC may be underestimating its own momentum. Notably, TSMC disclosed that quarterly revenue tied directly to cryptocurrency applications ranged between $340 million and $530 million—confirming mining's status as one of its fastest-growing segments.
While TSMC dominates the 7nm and 16nm foundry markets—holding nearly 100% market share in some advanced nodes—competitors like Samsung are aggressively pursuing opportunities in emerging areas such as crypto mining. Samsung has already secured partnerships with Chinese miner Baikal and collaborated with SilTerra, a subsidiary of United Microelectronics Corporation (UMC), to develop specialized IP for mining chips.
Despite occasional reports of collaboration—such as unverified claims of joint ASIC production—the reality remains one of intense competition. Both giants recognize the long-term value in high-speed computing infrastructure, with cryptocurrency serving as an early but powerful catalyst.
Bitmain's Strategic Edge Through TSMC Partnership
Bitmain, founded just four years ago, has rapidly ascended to become a dominant force in the global mining industry. Its success stems from proprietary ASIC designs powering its Antminer series, which consistently outperform competitors in computational efficiency and hash rate.
Contrary to rumors in March suggesting Bitmain drastically cut orders from TSMC, industry insiders confirm that production remains strong. The temporary dip in orders observed by downstream packaging and substrate suppliers was due to a transitional shift—moving 16nm ASIC production from Taiwan-based fabs to the newly operational Nanjing plant.
Current estimates indicate that Bitmain alone occupies approximately 20,000 wafers per month of 16nm capacity at the Nanjing facility. Additionally, Bitmain continues to place orders for 28nm chips and is expected to ramp up new tape-outs soon.
To meet surging demand, TSMC has dedicated an entire production line at the Nanjing site—capable of manufacturing 200,000 twelve-inch wafers monthly using 16nm process technology. This level of investment reflects both the scale of Bitmain’s operations and TSMC’s confidence in sustained demand.
From its first-generation Antminer S1 to today’s next-gen models, Bitmain has leveraged TSMC’s manufacturing excellence to achieve rapid ROI and market leadership. With new mining equipment slated for release in Q2 2025, the partnership shows no signs of slowing down.

Mining Momentum Remains Strong Despite Market Volatility
Even after significant corrections in Bitcoin’s price, mining activity has not waned. On the contrary, major Ethereum and Bitcoin mining farms—particularly those based in China—are upgrading their infrastructure to maintain profitability amid rising network difficulty.
TSMC reported that revenue from Chinese clients increased from 11% to 19% year-over-year—a jump strongly correlated with rising ASIC demand. While Morgan Stanley analysts have warned of declining mining margins, real-world investment patterns suggest ongoing confidence in long-term blockchain growth.
Although TSMC revised its 2018 revenue forecast downward—from 10–15% growth to around 10%—due to uncertainties in crypto demand, current trends indicate resilience. The company is well-positioned to recoup its $90 billion NT dollar investment in the Nanjing plant through sustained high-volume production.
