VAT acquires Atonarp, a mass spectrometry-based sensor company, for CHF 110 million to integrate real-time process monitoring and control into its vacuum subsystems portfolio. The acquisition targets sub-2nm semiconductor manufacturing, where in-situ sensing is becoming critical for process control and AI-driven autonomous manufacturing.

◆ ◆ The Wire takeaway
If you sell gases, precursor chemicals, or hardware into sub-2nm fabs, your customer just integrated real-time sensing into their process stack—and they now own the data from your inputs. You either supply VAT directly or you're competing against a supplier who knows exactly how your products perform in real time.
