I placed every company and laboratory that touches ultra-high vacuum onto a single map, two hundred and thirty-five of them, each pinned to the city where it sits. I did it to see the field I work inside from above, the way I watch a bake from a screen instead of standing at the chamber. The map made an argument on its own, before I had written a word beneath it.

The first thing it says, it says by where the pins are not. They crowd into three places, the American coasts, a band of small countries along the Rhine and the Alps, and a tight arc across Japan, Taiwan and Korea. Below the equator there is almost nothing. The emptiness that every frontier machine is built around, that fabs and colliders and fusion reactors depend on, is held up by three regions and left alone by the rest of the planet. The vacuum has three poles.

Then it says something quieter, which took the ownership data to see. The pumps that hold the world's vacuum carry famous names, and those names are owned by a few holding companies you would never stencil on a chamber. One Swedish group, Atlas Copco, controls Edwards in England, Leybold in Germany, and Gamma Vacuum and Montana Instruments in the United States, four of the names I trust on my own stations, flying four different flags, all steered from one country. Busch, a German group, holds Pfeiffer. The consolidation is real, but notice where it is not. Nobody has rolled up the headliners. ASML stands alone, TSMC stands alone, the names in every article about chips are not the ones being quietly gathered. The gathering is one layer down, on the ion pumps and the cryostats and the gauges, the parts nobody cites. That is where ownership is actually changing hands, and it changes hands in the dark, because no one is looking at the components.

A handful of these actors do not merely make a thing, they gate it. The list is short, and every entry is a single point where one failure, or one export order, stops the line.

Japan is worth stopping on, because the map corrects a lazy idea. Japan is not only a place that makes chips. It is a place that makes the tools that make the chips, and holds some of them alone. Lasertec, in Yokohama, is the only commercial source of actinic patterned-mask inspection for EUV, the machine that checks the mask before ASML's light ever prints it, a monopoly standing upstream of the monopoly. DISCO holds the dicing and grinding of finished wafers to nearly the same degree. The country that gets filed away as one fab among many is, in tooling, a lock.

Here is the turn. The flag on the pin is rarely the flag that owns it. Edwards sits in England and answers to Sweden. Nor-Cal sits in California and answers to Germany. Cryomech sits in New York and answers to Finland. When I recolor the map by who controls each actor instead of by where it stands, the picture rearranges, and the rearrangement is the whole point. The map of where the work is done and the map of who owns the work are not the same map. Almost everyone reads the first one. The second is the one that decides what happens when a border closes.

![The map recolored by control rather than location, a scatter of pins across five countries all turning the same color to show they are steered from somewhere else.](../../assets/essays/chain-fig3-control.png)

And there is a last move, and the ground under it is still shifting. The hardware that holds the vacuum is made across a scatter of small countries, each a national monopoly in one narrow thing, Dutch light, German and Swedish pumps, Swiss valves, Italian getters, Austrian metals, French helium. That sovereignty is real, it is physical, and it is hard to move. But the value is leaving it. The layer that is starting to matter is not the pump, it is the data coming off the pump, the predictive service, the telemetry, the model that warns a fab a pump will fail before it does. That layer is sold by the equipment vendors themselves, but it runs on American clouds, a dependence one layer further up. The countries that make the machine do not hold the layer that is learning to own the machine. Sovereignty over the metal is being quietly refinanced through the infrastructure that watches it.

Step back, and the map was never really about vacuum. It is a small and honest instance of a general law, that the thing you manufacture and the thing that holds the leverage drift apart over time, and the leverage settles on whoever sits one layer above. I can read it cleanly in the vacuum chain only because I drew that chain by hand, node by node, and the ownership refused to collapse into a slogan. It collapsed into this instead. The famous names are a distraction. The chain is held beneath them, by owners flying flags that are not their own, and it is being refinanced from above, in a layer that flies just one.

So the pins glow where the work is done, and the work is real, and the names on it are the ones everyone knows. They are only not the names that own it, and less and less the names that will keep what it earns. The chips have their headlines. The vacuum is held, and quietly bought, by the names nobody cites.

Under this map sits a floor of its own, the load-bearing vacuum beneath the fabs. The map itself is the [world map](/actors/world/), actor by actor.

- Ownership and consolidation, drawn from the acquirers' own announcements: Atlas Copco's acquisitions of Edwards, Leybold, Gamma Vacuum and Montana Instruments; Busch Group's ownership of Pfeiffer Vacuum; Pfeiffer's acquisition of Nor-Cal Products; Bluefors' acquisition of Cryomech. Cross-checked against each company's corporate and investor pages.
- Chokepoint positions, from company disclosures and standard semiconductor supply-chain reporting: ASML as sole EUV lithography supplier; Lasertec as the only commercial actinic patterned-mask inspection tool for EUV; VAT in ultra-high-vacuum gate valves; SAES in getters; Plansee in refractory metals; DISCO in wafer dicing and grinding; the large cryoplant duopoly of Air Liquide and Linde Kryotechnik, the Swiss cryoplant arm of Linde; TSMC at over 90 percent of leading-edge logic.
- The value migrating to a data layer above the hardware: the predictive and telemetry services now sold by the equipment vendors themselves, including Edwards' Semiconductor Intelligent Service, Applied Materials' and Lam Research's equipment-analytics platforms, all running on external cloud infrastructure.
- Actor positions, sectors and control coding: the Mean Free Path Actors map and its actor-control layer, a hand-built synthesis of the above, joined actor by actor.
