TSMC's Nanjing 12-inch wafer fab has achieved a remarkable milestone by completing construction and commencing mass production of 16nm-grade wafers within just 20 months. This facility now stands as China's first production base for advanced 16nm process technology, with its initial batch of chips destined for Bitmain, the global leader in cryptocurrency mining hardware.
Semiconductor Hub: Nanjing's Strategic Transformation
The Nanjing municipal government has successfully transformed this historical capital into a semiconductor powerhouse since 2015, attracting industry giants like TSMC and Unisoc. This development created a comprehensive ecosystem encompassing:
- Chip design
- Wafer fabrication
- Packaging and testing
China's semiconductor market demonstrates staggering demand, accounting for over 60% of global semiconductor purchases ($250 billion out of $400 billion in 2017). Nanjing officials anticipate TSMC's local production will significantly boost domestic semiconductor self-sufficiency.
The Mining Chip Battlefield
Cryptocurrency mining has emerged as a pivotal growth driver for TSMC:
- The company secured over 90% of global mining chip foundry market share
- High-performance computing (HPC) revenues may grow 37.5-43.75% year-over-year
- Quarterly crypto-related revenue reached $340-$530 million

While TSMC dominates 7nm production, competitors like Samsung have entered the arena through partnerships with Chinese mining hardware manufacturers, highlighting the sector's strategic importance.
Bitmain's Massive Order
Contrary to earlier rumors about order reductions:
- Bitmain has secured 20,000 monthly 16nm wafer capacity at TSMC Nanjing
- The facility dedicated a production line for 200,000 monthly mining chips
- 28nm ASIC chip production continues smoothly
Bitmain's rapid rise (founded just 4 years ago) demonstrates the mining sector's explosive growth potential, with their Antminer series leading market performance.
Mining Industry Momentum Continues
Key industry trends:
| Metric | Value | Significance |
|---|---|---|
| China client revenue share | 19% (up from 11%) | Mining-driven growth |
| HPC revenue target | 25% of total | Up from 20% in 2017 |
| Crypto revenue potential | $530M/quarter | Major revenue stream |
Despite Bitcoin's price volatility:
- Mining operations continue expanding globally
- Equipment upgrades remain priority for major farms
- Bitmain plans Q2 new miner releases
