“A fab is like an iceberg,” someone tells me. I can’t tell who because we’re all covered head to toe in clean-room garb. A tour of GlobalFoundriesFab 8 in Malta, N.Y., certainly reinforces that analogy: We’ve just come up from the “sub-fab,” the 10 meters of vertical space under the floor, where pipes and wires snake down from each semiconductor-manufacturing tool above to a set of automated chemical handlers, water analyzers, power conditioners, and—in the case of the unit I’ve come to see—kilowatt-class lasers.

The laser system takes up 15 to 20 square meters out of perhaps 80 square meters of the floor space required for a single machine. About halfway through a six-week assembly process of mind-bending complexity, the equipment making up the tip of the iceberg is a house-size agglomeration of shiny metal tubes, opaque chambers, and wiring. A half dozen bunny-suited technicians are moving around the behemoth, probing and connecting things in a carefully choreographed procedure.

The EV Transition Explained: Charger Infrastructure

How many, where, and who pays?

The ability to conveniently charge an EV away from home is a top concern for many EV owners. A 2022 survey of EV owners by Forbes indicates that 62 percent of respondents are so anxious about their EV range that travel plans have been affected. While “range anxiety” may be overblown, the need for an extensive and reliable external charging infrastructure is not.

Infrastructure terminology can itself be confusing. For clarity, bear in mind that a charging station is a specific physical location which has one or more charging posts. A charging post itself may have one or more ports, where each port can charge a single EV. Each post may have multiple types of service connectors to support different EV charging connector standards. And a port may supply varying power levels.
