Common Questions
Why is KLA-Tencor building a plant in Germany?
The European Commission approved €74.4m of state aid on 14 July 2026 to help KLA-Tencor's metrology Arm build a plant in Hesse.Source: event
What does KLA-Tencor do?
KLA-Tencor makes process-control and metrology equipment that semiconductor fabs use to inspect wafers and catch defects during chip manufacturing.Source: event
Is KLA-Tencor the same company as ASML?
No. ASML makes lithography machines; KLA-Tencor makes the separate metrology and inspection equipment fabs use to check chips during production.Source: event

Background

KLA-Tencor's metrology Arm was one of four German recipients when the European Commission approved €659m in Chips Act state aid on 14 July, taking €74.4m towards a chip-metrology plant in Hesse .

KLA (long known as KLA-Tencor, formed by the 1997 merger of KLA Instruments and Tencor Instruments) is a US company headquartered in Milpitas, California, and listed on Nasdaq. It does not make chips itself; it makes the process-control and metrology equipment fabs use to inspect wafers and catch defects during manufacturing, work that sits alongside lithography (ASML) and deposition/etch (Applied Materials, Lam Research) as one of the pillars of the chip-equipment supply chain.

The Hesse investment extends that role into Europe's own fab build-out, giving the continent's Chips Act projects the inspection tooling needed to hit yield, the less visible but essential counterpart to the lithography and wafer-fab spending that dominates sovereignty headlines.
