Nanya Technology is preparing a new fab in Pingtung, in southern Taiwan, focused on 3D chip packaging using TSV and wafer-stacking technologies. The project comes as artificial intelligence drives up demand for high-bandwidth memory (HBM) and turns advanced packaging into an increasingly important part of the supply chain for AI accelerators and servers.
Nanya and 3D packaging in 30 seconds
- Nanya Technology has received approval to build a new fab in Pingtung.
- The project will focus on 3D packaging using TSV and wafer stacking.
- The company is aiming to join the supply chain tied to high-bandwidth memory.
- Nanya hasn’t disclosed the specific investment figure yet.
- The move coincides with new expansions by Micron and Winbond in Taiwan to meet AI-driven demand.
The decision places Nanya Technology in a part of the semiconductor industry that’s gaining weight as AI systems need more memory and more bandwidth. The company, part of the Formosa Plastics group and specialized in DRAM, isn’t just looking to boost conventional production — it’s moving toward three-dimensional integration processes.
The Pingtung project has been approved by Taiwan’s National Science and Technology Council and will be the county’s first semiconductor fab of this kind. The facility will be geared toward 3D packaging and will use TSV (Through-Silicon Via) technology, which creates vertical connections through silicon.
Wafer stacking is another technology tied to the project. Both techniques matter for building devices with higher interconnect density and for shortening the distances data has to travel between different layers of a chip or memory module.
Nanya looks for a place in the AI supply chain
Nanya’s expansion comes as HBM has become one of the most sought-after components for AI computing systems. This type of memory delivers high bandwidth alongside processors and accelerators that need to move huge amounts of data.
The growth of AI data centers has shifted memory makers’ priorities. Producing conventional DRAM still matters, but packaging and stacking technologies make it possible to build denser solutions suited to high-bandwidth workloads.
Nanya still hasn’t publicly disclosed the investment tied to its new Pingtung fab. Industry estimates cited in the report put a facility of this kind above NT$100 billion, though that figure comes from industry estimates rather than an official company forecast.
The move also fits into a broader expansion of memory capacity in Taiwan. Micron is expanding its facilities in the country and is preparing a second HBM packaging plant in Taichung, while also adding capacity in Tongluo, Taoyuan, and Tainan.
Micron has invested more than NT$1.6 trillion in Taiwan to date, according to the figures cited in the report. Winbond is also expanding capacity in Kaohsiung.
Taken together, these projects point to a growing concentration of investment in advanced memory and packaging on the island. The report estimates that the additional investments from the three memory makers combined could approach NT$200 billion.
Packaging becomes another piece of the AI race
Nanya’s move reflects a shift in how companies compete in the memory market. The performance of an AI solution no longer depends solely on the process used to manufacture the memory chip. How different components are integrated and connected also shapes bandwidth, density, and integration options.
3D packaging makes it possible to work with multiple layers and build vertical connections between them. For HBM, this approach matters especially because that memory is built from multiple stacked layers of DRAM connected through TSV.
Nanya hasn’t said in the material available that it will produce exactly the same type of HBM supplied by the leading specialized manufacturers. The Pingtung project is geared toward 3D packaging technologies tied to the needs of high-bandwidth memory.
That distinction matters. The new fab expands Nanya’s technological capabilities, but it’s still too early to say the company will become a supplier on par with today’s major HBM manufacturers, such as Nanya’s own earlier investment push following the surge in DRAM prices suggested.
For Taiwan, the move also has an industrial dimension. The country already concentrates much of the world’s chip manufacturing and has an extensive network of suppliers for equipment, materials, assembly, and packaging. Nanya’s expansion adds capacity in a manufacturing stage that’s gaining weight as AI accelerators grow.
The Pingtung location also broadens the geography of Taiwan’s semiconductor infrastructure. Until now, much of the island’s advanced chip and memory production has been concentrated in other industrial zones. A new Nanya fab brings southern Taiwan into this expansion of capacity.
The project still has a way to go before it turns into commercial production. The company will need to move forward with construction and start-up, as well as define the specific scope of the technologies and products it will manufacture there.
What’s already clear is the direction of the investment: Nanya wants to grow its presence in advanced packaging and build capacity for a memory market increasingly shaped by AI demand. In an industry where HBM manufacturing capacity is under heavy pressure, 3D packaging is becoming a technology memory makers can’t afford to ignore.
FAQ
What will Nanya manufacture in Pingtung?
Nanya is preparing a fab focused on 3D chip packaging, using TSV and wafer-stacking technologies. The project is tied to the needs of high-bandwidth memory.
How is the project related to HBM memory?
HBM uses multiple stacked layers of memory connected through TSV. Nanya’s project uses similar packaging technologies, though the available information doesn’t confirm the fab will produce exactly the same type of HBM as today’s leading manufacturers.
How much will Nanya invest in the new fab?
Nanya hasn’t disclosed the specific investment for the project. Industry estimates cited in the report put a facility of this kind above NT$100 billion.
Why is demand for advanced packaging growing?
AI systems need to move huge amounts of data between processors and memory. 3D packaging and stacking make it possible to increase integration density and create high-speed connections between different layers.
