The deal, reported by DIGITIMES, is more than an entry in the semiconductor M&A ledger: it’s a concrete piece of a strategy aimed at redrawing the geography of chip production, especially for AI workloads. Greatek Electronics, a Taiwan-based packaging and testing house, has finalized the purchase of the plant that Onsemi owned in the Philippines. The move fits into the so-called “Taiwan+1” plan, designed to expand manufacturing presence beyond the island – currently the indispensable but also vulnerable epicenter of the global semiconductor industry.

Why packaging matters (especially now)

In the LLM space and for locally run software, attention is often monopolized by the silicon: H100 GPUs, custom accelerators, boards with generous VRAM and high bandwidth. Yet none of these processors would make it onto a card without advanced packaging – the set of techniques that encapsulate the silicon, connect memory and logic, and manage thermal dissipation and signals. Technologies like TSMC’s CoWoS or ABF substrates have become well-known bottlenecks: AI demand has saturated high-end packaging capacity, stretching lead times and affecting the TCO of those building on-premise clusters.

Acquiring a packaging plant in a country like the Philippines – already part of an established electronics supply chain – does not solve the problem on its own, but it broadens the available production base. Greatek, traditionally focused on power semiconductor and discrete device packages, now gains a lever to extend its portfolio toward more complex applications, potentially including AI-related ones, at a time when every square meter of clean room dedicated to packaging is being contested.

Diversification and geopolitical risks

“Taiwan+1” is not a slogan but a response to very real pressures. The concentration of advanced manufacturing in Taiwan exposes the entire chain to risks ranging from tensions in the Strait to extreme events like earthquakes. Downstream companies – from server suppliers to system integrators assembling nodes for self-hosted inference – are starting to assess more rigorously the resilience of critical component supply. In this light, Onsemi’s Philippine plant, already operational and staffed with local expertise, gives Greatek a fast ramp to additional capacity located outside Taiwan.

This is not an isolated case. Other Taiwanese OSATs – ASE Technology Holding, Powertech Technology – have taken similar steps in Malaysia, Singapore, or Japan. The shared goal is to prevent a single breaking point from paralyzing the entire production flow, precisely when generative AI demands growing volumes of complex packages. For those planning an on-premise LLM installation, these dynamics are not abstract: they affect cost predictability, procurement timelines, and ultimately the feasibility of certain projects.

A piece of the puzzle for local AI infrastructure

The transfer of the facility has been completed, but the real impact will be measured in the coming quarters, as Greatek begins integrating the production lines into its network. From the perspective of those designing on-premise deployments, such signals are small indicators of a structural transformation: packaging, long considered a low-value-added link, is becoming as valuable as advanced lithography. The ability to meet demand for AI accelerators – including boards with HBM or multi-die chiplets – will depend on how many sites like the Philippine one can be repurposed.

The acquisition does not directly involve high-bandwidth memory or NVLink fabrics, but it affects the mosaic of suppliers that determines the quality and availability of components ending up in private data center racks. In a sector where every watt and every gigabyte of VRAM counts, supply chain robustness is the precondition for architectural choices – quantization, balancing local versus remote inference – to be made with real freedom, rather than being dictated by simple hardware unavailability.

The open question remains whether the “+1” can truly be enough to mitigate dependence on Taiwan, or if, for now, it is a safety net that would only come into play in extreme scenarios. Greatek’s expansion nonetheless suggests that the market is pricing in the possibility of having to rely on multiple geographical nodes, a consideration that IT managers would do well to incorporate into long-term planning.
