The claim

The statement under review is: "Stable water supply to the Honam semiconductor cluster is difficult," presented as the assessment of a National Assembly Research Service report that has now been disclosed to the public. The Honam semiconductor cluster is among the sites positioned as future semiconductor manufacturing bases, and questions over whether it can reliably obtain the water its fabs would require have been raised repeatedly as infrastructure planning moves forward.

Why water supply matters for fabs

Water is a foundational input for semiconductor fabrication. fabs consume large volumes of ultrapure water in cleaning and etching processes, and an unreliable supply can force production stoppages regardless of how advanced a line's equipment may be. For that reason, water availability is treated as a site-selection and infrastructure variable on par with power supply and land. An assessment by the legislature's own research arm that stable supply to a designated cluster would be difficult therefore carries direct relevance for companies weighing investment timelines and for regional governments tasked with securing the necessary water infrastructure.

Verification and assessment

Our review began with the disclosed National Assembly Research Service report itself, which is the primary basis of the claim. The 12 primary sources examined in the course of verification were consistent with the report's core judgment that stable water supply to the Honam semiconductor cluster cannot be taken for granted. The rating reflects that the essential assertion stands as stated, while the underlying analysis is a forward-looking infrastructure assessment rather than a finding of an existing supply failure.

On the basis of the disclosed report and our review of the primary record, we rate the claim Mostly True.
