SK hynix says HBM4 mass production is set for 2H 2026, with volume production in 2027
In a live Q&A on HBM4, SK hynix said time-to-market, performance, yield, and customer trust are hard to replicate quickly.
Key takeaways:
- Mass production is targeted for the second half of 2026.
- Yield and quality for key customers should be near HBM3E levels during ramp-up.
- Volume production is expected in 2027.
- The company is also exploring hybrid bonding and next-generation work, including HBM5.
The update underscores how memory vendors are treating advanced HBM as a multi-year race in capacity, yield, and customer qualification.
