Gradiant is building a water treatment facility for one of Germany's upcoming chip fabs, according to a report from The Register. Gradiant did not disclose who would be making the fab in question, saying only that it is a "large semiconductor manufacturer" — making the most likely candidates TSMC or Intel. The water treatment plant will also receive funding from the European Chips Act, which is partially funded by Germany.
The water treatment facility will reportedly be built by Gradiant's subsidiary, German water treatment company H+E Group, which Gradiant acquired just last year (giving the company a presence in Germany). H+E hasn't had any high-profile dealings with either TSMC or Intel, but TSMC is a known customer of Gradiant, and the fab may belong to TSMC.
TSMC's new fab in Germany is located in Dresden, Saxony, and is a joint collaboration between the Taiwanese company and European companies Bosch, Infineon, and NXP. The fab is set to produce chips on TSMC's 12nm, 16nm, 22nm, and 28nm nodes, which are very mature at this point — far from the cutting-edge, but very cheap and efficient to produce chips on.
Another hint toward the identity of the fab's owner: it will produce chips for "renewable energy, datacenter, and electric vehicle markets." Datacenter chip production is of particular note, as Intel's cutting-edge nodes will certainly be used for datacenter class CPUs and GPUs, while the chips from TSMC's fabs are expected to be used in cars. This still isn't quite enough to narrow down the mystery fab builder, however.
