Semiconductor manufacturing is about to get a precision upgrade. Hanmi Semiconductor, a South Korean leader in bonding technology, has unveiled a new Wide TC Bonder—a machine designed to replace older hybrid bonding methods and enable faster, more reliable production of high-bandwidth memory (HBM) stacks. The announcement, made ahead of its debut at Semicon Korea 2026, signals a critical step forward for the industry’s push toward HBM5 and HBM6, which are expected to power next-generation AI accelerators and data centers.
The Wide TC Bonder introduces fluxless bonding technology, a refinement that eliminates the need for chemical adhesives in the stacking process. This shift is expected to improve production yields, reduce defects, and enhance overall quality—key factors as memory manufacturers scale up for advanced nodes. While the technology is backward-compatible with existing HBM4 designs, its true potential lies in enabling the mass production of HBM5 and HBM6, which are projected to debut in the coming years.
HBM memory is the backbone of high-performance computing, particularly in AI and machine learning workloads. The transition from HBM4 to HBM5 and beyond requires not just smaller process nodes but also more efficient bonding techniques to stack memory layers without compromising performance. Hanmi’s new equipment could address long-standing challenges in hybrid bonding, which has faced repeated delays due to technical hurdles.
What sets the Wide TC Bonder apart is its focus on precision and scalability. Early from Hanmi suggest the technology will improve bonding completeness—reducing gaps or misalignments between memory layers—while also supporting higher throughput. This could be particularly beneficial for manufacturers gearing up for HBM5, which is expected to leverage 2 nm process technology, and HBM6, which may follow in subsequent years.
The timing of this announcement aligns with broader industry trends. Earlier this year, a joint study by KAIST and TERA outlined a roadmap for HBM development, predicting HBM4’s initial deployment in AI accelerators like NVIDIA’s Rubin architecture before expanding into HBM7 by the late 2030s. Hanmi’s Wide TC Bonder could play a pivotal role in ensuring that manufacturers stay on track with this ambitious timeline.
For now, the equipment is slated for commercial release in the latter half of 2026. If successful, it could reshape the landscape of memory production, making it easier for companies to adopt advanced HBM stacks without the bottlenecks that have plagued earlier generations.
