Semiconductors and Lithography: Quantum for Chip Design and Quantum Chips Made by Chip Tools
Two stories that get mixed up
Search for "quantum semiconductors" and you find two very different things. Story one: quantum computers used as a tool to design or simulate chips, for example in lithography, the light-based step that prints circuits. Story two: chip factories used to manufacture quantum computers, such as silicon spin qubits. Both are interesting. Only the second has hardware to show today. Keep them apart. For the second, see silicon spin qubits explained and why manufacturability matters.
Story one: quantum helping to design chips
Samsung SDS. Quantum Zeitgeist, citing a Seoul Economic Daily report of 1 July 2026, reports that Samsung SDS is researching quantum computing for photolithography, with a proof of concept planned to start in the second half of 2026. The reported design is hybrid: quantum computers run core calculations, classical computers process results, and AI detects and corrects quantum computation errors. The technology is meant for Samsung Electronics' semiconductor R&D, not as a product. Expected benefits include lower time and cost in pattern design and etching, and better integration density. Cautions: the company "reportedly" has some algorithms, their effectiveness is unverified until the test, no hardware or vendor is named, no performance data exists, and Samsung had not confirmed the details in the pieces we read. One secondary outlet in our search gave a different timeline, which looks like an error, but it shows how loosely this story is being repeated.
Xanadu and Mitsubishi Chemical. Quantum Zeitgeist reported on 3 July 2025 that the two began a project on quantum algorithms for extreme ultraviolet (EUV) lithography, with a 2 million dollar investment and a three-year goal to demonstrate practical application. The aim is to simulate quantum effects such as Auger decay, light-matter interactions and secondary electron emission, in order to speed discovery of better photoresist materials. Mitsubishi supplies photoresist data and Xanadu designs the algorithms. No hardware is named and no results are reported. The company plan rests on photonic hardware ambitions that still need fault tolerance to matter for such chemistry.
Why would physics matter in lithography? EUV light knocks electrons around inside the photoresist, a quantum process that is hard to model. That is chemistry-like simulation, which is why this shares logic with the chemistry case. If it works, it likely needs error-corrected machines, not today's noisy ones.
Story two: chip tools building quantum chips
Electronics For You reported on 20 May 2026 that imec announced, at ITF World, what it calls the first quantum dot spin qubit device fabricated with High-NA EUV lithography. The article says functioning qubit structures were made with gaps as small as 6 nanometers between control electrodes, and that this could theoretically allow millions of qubits on one chip. It also says the work is progress toward reproducible 300 mm wafer-compatible manufacturing. Notice what is missing: no coherence times, gate fidelities or qubit counts of a working processor were reported. The "millions of qubits" line is theoretical. Fabricating a device is not the same as having a good qubit.
Fraunhofer IPMS reported in 2026 that a European pilot line called SPINS, focused on semiconductor spin qubits, launched with 50 million euros of EU co-funding. We know this from a search summary, which also attributed coordination to imec and 25 partners; we did not read the page, so treat those details as reported. Pilot lines matter because they move quantum hardware from one-off lab builds toward repeatable manufacturing.
Names we could not confirm
Searches for Intel, TSMC, GlobalFoundries and Applied Materials returned no quantum chip design or lithography pilot in what we read, so we make no claims about them. Intel is known for silicon spin qubit work, but we did not verify recent specifics here.
Hype check
- Hype: "quantum computers will design the next chip." No source we read reports one doing so, even at small scale.
- Hype: mixing the two stories, so that a qubit-fabrication milestone gets presented as quantum-powered chipmaking.
- Real: funded, named projects with defined science goals and, in imec's case, fabrication hardware.
- Honest unknown: whether classical methods, including AI, will solve lithography modeling first.
What to watch
Watch for the Samsung SDS test outcome (if published at all, since it is an internal project), early Xanadu and Mitsubishi algorithm resource estimates, and imec's qubit performance data once devices are measured.
