Hanmi Semiconductor Co., Ltd. occupies a discreet but strategic position in the electronics industry: the equipment that turns chips fabricated on silicon into components that are assembled, tested and ready for integration into systems. Based in Incheon, South Korea, the company does not produce semiconductors itself. It supplies machines to manufacturers responsible for their assembly and packaging, a set of operations often referred to by the English term “packaging”.
A trajectory rooted in Korean industry
Hanmi Semiconductor was founded in 1980 by Kwak No-kwon, in a country that was then building its industrial strength in electronics. Its development has accompanied that of the Korean semiconductor industry, while also targeting an international customer base. The company is listed on the Korea Exchange’s main KOSPI market.
Its specialization has developed around the stages that follow the fabrication of circuits on silicon wafers. Long less visible than transistor etching, these operations have become crucial to component performance. The growing number of chips brought together in a single package and the use of three-dimensional architectures are increasing the demands for precision, throughput and reliability that its equipment must meet.
From component processing to memory stacking
Hanmi’s portfolio includes precision cutting, inspection and component handling systems. Its “Vision Placement” equipment combines vision inspection and placement functions in package processing operations. The industrial challenge is to automate these stages while limiting defects and material losses.
The company is also known for its thermocompression bonding machines, or “TC bonders”. These combine heat, pressure and precise alignment to assemble chips. They are used notably in the production of HBM, or “High Bandwidth Memory”, which consists of several layers of memory stacked and interconnected.
These memory devices feed data to processors used for high-performance computing and artificial intelligence. Their value lies in the available bandwidth and their integration close to the computing units. For Hanmi, this development shifts some industrial value toward advanced assembly: final performance no longer depends solely on transistors, but also on how the different chips are brought together.
What next?
Growing demand for HBM represents an important market opportunity, but it eliminates neither manufacturers’ investment cycles nor competition among equipment makers. Hanmi will need to keep pace with evolving chip stacks, maintain production yields and adapt its machines to new generations of components. The development of processes such as hybrid bonding, which takes a different approach to interconnection, is also a technological issue to watch. Its trajectory will therefore depend as much on AI-related demand as on its ability to keep pace with manufacturers’ technical choices.
