Introduction:
In the fast-moving world of AI and high-performance computing, memory is the fuel—and HBM4 and Advanced Packaging Race is the high-octane upgrade everyone wants. Building these powerful memory stacks isn’t easy. It takes cutting-edge tools, microscopic precision, and massive investment. Now, three semiconductor giants—Hanmi Semiconductor, AMEC, and ACM Research—are stepping up with new technologies and billions in R&D to lead the next phase of the chipmaking race.
As demand for faster, cooler, and smarter chips grows, these companies are not just competing—they’re redefining how future AI hardware gets built.

Quick Overview
Hanmi Semiconductor launches TC Bonder 4, a bonding machine designed for HBM4, targeting mass production by late 2025.
AMEC achieves full-stack capability in HBM tools including CCP etching, CVD, PVD, and TSV technologies, ready for volume deployment.
ACM Research raises RMB 4.5 billion (~$620M) to expand advanced HBM equipment like electroplated copper (ECP) and ultra-clean wet cleaning tools.
HBM4 promises 60% faster speeds and 30% lower power consumption compared to HBM3E, supporting up to 16-layer stacks and 2,048 TSVs.
Asia strengthens its position as a hub for advanced memory and packaging amid tightening U.S.-China export controls.

Hanmi Semiconductor Drives HBM4 Packaging Forward
On May 14, Hanmi Semiconductor unveiled the TC Bonder 4, a specialized bonding machine made for mass production of HBM4. This machine marks a leap forward for South Korea’s semiconductor ecosystem. Hanmi also established a dedicated R&D team focused on HBM4, targeting faster, more precise bonding processes tailored to the relaxed die height specs of HBM4.
Chairman Kwak Dong-shin stated,
“The TC Bonder 4 is a game-changer. It accelerates bonding accuracy for multi-layer stacks and will support the future of AI memory demands.”
HBM4 specifications:
- 60% faster than HBM3E
- 30% less power consumption
- Up to 16-layer stacking
- Support for 2,048 TSVs (Through-Silicon Vias)
These improvements allow chips to handle growing AI workloads and massive data-center operations more efficiently.
AMEC Advances TSV Etching and Full HBM Tool Suite
Chinese semiconductor equipment maker AMEC announced on June 9 that it expanded its HBM and advanced packaging tool portfolio significantly. AMEC now offers:
| Process | Equipment Type | Production Status |
|---|---|---|
| TSV Etching | Deep Silicon Etcher | Mass production ready |
| CVD/PVD | Thin-film Deposition | Deployed |
| Metrology | Wafer Inspection | Operational |
| Etching | CCP Etchers | Commercial launch |
AMEC’s breakthrough in in-house TSV etching means it can produce silicon vias with the precision needed for 3D memory stacking. TSVs are vertical connections that allow data to travel between layers quickly, crucial for HBM performance.
An AMEC spokesperson explained,
“Our CCP etchers and deep TSV silicon etchers meet volume production standards, enabling next-gen memory solutions.”
ACM Research Raises $620 Million to Expand HBM Equipment
On June 6, ACM Research (Shanghai) secured RMB 4.482 billion (~$620 million) through a private placement aimed at boosting HBM-related R&D and manufacturing.
Investment breakdown:
- RMB 922 million for R&D test platforms
- RMB 2.255 billion for equipment upgrades and iterations
- RMB 1.304 billion for working capital
ACM’s strengths lie in wet cleaning tools and electroplated copper (ECP) equipment. Their Ultra C Series wet cleaners eliminate particles smaller than 10 nanometers—vital for improving TSV yields. Their Ultra ECP GIII platform enables precise copper plating of micro-bumps and TSVs, ensuring reliable electrical connections in complex HPC and AI chip packages.
Think of ECP as the “plumbing system” inside these skyscrapers—without clean, copper-filled TSVs, data flow chokes and performance suffers.

Asia’s Strategic Rise in the Global Chip War
While American giants like Applied Materials and Lam Research remain dominant, Asian equipment makers are rapidly closing the gap. U.S. export restrictions on Chinese tech firms have opened opportunities for AMEC and ACM Research to fill critical supply gaps. Meanwhile, Hanmi’s early lead in HBM4 tooling could boost South Korea’s semiconductor packaging leadership.
Why this matters now:
- Global demand for HBM skyrockets. SK hynix and Samsung push to supply Nvidia, AMD, and other AI GPU makers.
- AI workloads demand faster memory with lower power draw.
- Self-reliance in equipment tools becomes a strategic imperative amid geopolitical tensions.
