Counterpoint Research said Thursday that memory chip manufacturers are actively pushing hybrid bonding as a key differentiator, with SK Hynix leading the shift toward scaling the technology for high-volume production.

Hybrid Bonding Emerges As Key Battleground

The firm highlighted that rising demand for AI and high-performance computing is forcing the industry to move beyond current micro-bump technology, which is hitting limits in power, performance, and heat.

In response, companies like Samsung Electronics Co, Ltd (OTC:SSNLF), SK Hynix, and Micron Technology Inc (NASDAQ:MU) are advancing hybrid bonding to enable denser, faster, and more efficient memory stacks.

Ecosystem Shifts As Demand Pressures Rise

At the same time, Applied Materials Inc (NASDAQ:AMAT) and BE Semiconductor Industries (OTC:BESIY) are integrating tools and processes to reduce manufacturing complexity and improve yields, addressing challenges tied to surface precision and defects.

Counterpoint added that while relaxed standards and process sensitivity may slow adoption in the near term, the long-term shift to hybrid bonding remains inevitable.

Demand from Nvidia Corp’s (NASDAQ:NVDA) AI workloads is pushing suppliers to align their roadmaps and accelerate the transition as performance needs increase across the industry.

Supply Crunch And Competition Intensify

Meanwhile, AI-driven data center spending is tightening the global memory market, pushing prices higher and limiting supply for other sectors.

Synopsys, Inc (NASDAQ:SNPS) CEO Sassine Ghazi said most memory output is now going to AI infrastructure, leaving less available for other uses. “Now it’s a golden time for the memory companies,” Ghazi said, adding that the shortage is likely to last through 2026 and 2027 due to slow capacity expansion.

At the same time, Samsung and SK Hynix are stepping up competition in AI memory, with Samsung advancing HBM4 (High Bandwidth Memory 4) production while SK Hynix expands capacity and secures supply deals to defend its lead.
