GlobalFoundries has completed the topping-out stage of its SPRINT semiconductor factory expansion in Dresden, Germany, advancing a €1.1bn manufacturing investment designed to raise the site’s annual capacity beyond one million 300mm wafers by the end of 2028. The construction milestone concerns additional cleanroom and production infrastructure at an existing operating fab, rather than the opening of a new production line.
GlobalFoundries announced the €1.1bn investment in October 2025, making the topping-out ceremony on 9 October 2026 the new development. The company says that phase was completed on schedule and within budget. General contractor Exyte is extending production infrastructure next to existing operations, so new construction activities and utility connections have to be managed without compromising equipment already manufacturing semiconductor wafers. Structural completion marks progress on the building, but does not demonstrate that the new production systems have been installed or qualified.
Dresden’s existing capacity is up to 950,000 300mm wafers annually, depending on product mix, according to GlobalFoundries. SPRINT aims to take that figure beyond one million by the end of 2028. These are capacity figures rather than actual shipment counts, and the increase should not be characterised as a doubling of output. The number of saleable chips obtained from a wafer varies with device size, manufacturing yield and the process steps required for each design.
A wafer fab’s effective output is governed by the sequence of lithography, deposition, etching, implantation, cleaning, inspection and other processes through which each wafer passes. Hundreds of tightly controlled operations may be needed before individual semiconductor devices can be tested and separated. Capacity therefore depends on tool availability, process time, wafer starts, product complexity, maintenance and yield as well as available floor space.
Cleanroom floor space is only one part of a wafer factory’s productive capacity. Fabrication equipment also requires stable high-quality electrical supply, ultrapure water, carefully controlled process gases, chemical distribution, exhaust handling and extremely stable environmental conditions. A building may have reached its final structural height while extensive utility, tool installation and qualification work remains. New equipment must then demonstrate the required process repeatability before wafers produced on it can be accepted within an established manufacturing flow.
Because contamination or uncontrolled vibration can affect fabrication results, the construction programme must also protect the neighbouring operating lines. Physical separation, traffic routes for contractors and equipment, utility changeovers, and controlled shutdown windows can constrain work even when a new production area is structurally complete. Exyte has said that the planned work on cleanroom and manufacturing infrastructure is progressing alongside the existing facility’s operations.
The Dresden fab makes differentiated semiconductor technologies serving industrial, automotive, aerospace and communications applications. Such components often combine requirements for long product lifetimes, analogue sensing, power management or radio-frequency performance with digital control. Their manufacturing priorities can differ from those of the most densely scaled processors, where transistor density dominates the commercial discussion.
Alongside the construction milestone, GlobalFoundries announced a separate technology roadmap for FDX Fusion, its proposed next generation of fully depleted silicon-on-insulator manufacturing. That process is intended to integrate sensing, digital processing, radio-frequency and related functions, with Dresden manufacturing targeted for 2028. The technology programme and SPRINT infrastructure expansion have different approval and qualification requirements. Proposed FDX Fusion development under the IPCEI programme remains contingent on German federal approval, while the factory building project proceeds through its own construction and equipment milestones.
Approximately 3,000 people work at GlobalFoundries’ Dresden site, which has around 60,000 square metres of cleanroom and laboratory space. The manufacturer reports more than €10bn invested there since 2009. Support for the current expansion comes through a European Chips Act framework involving the EU, Germany and Saxony. Qualified wafer shipments will depend on the commissioning and process qualification stages still ahead.
Industrial and automotive customers will need the expanded wafer lines to reproduce specified electrical characteristics reliably before devices can enter approved products. Process monitoring, yield stabilisation, packaging and customer-specific reliability testing can extend beyond initial tool commissioning. The construction timetable thus supplies one milestone toward eventual supply, while actual delivery capacity will follow equipment qualification and allocation across product lines.
GlobalFoundries expects the Dresden expansion to support semiconductor production flows that remain within Europe for customers with stringent security or sourcing requirements. Process availability, customer qualification and the eventual distribution of wafer starts will determine which devices can use that route. Following structural topping-out, infrastructure installation and production-equipment qualification remain on the path to the end-2028 capacity objective.
