Semi Catalog 2026

I build semiconductor equipment for a living: EFEMs, vacuum transfer modules, load ports, aligners and the process chambers that hang off them. Every one of those machines is a bill of materials made of other people's products, and every one ends up in someone else's fab. So whenever a SEMICON show comes around, the exhibitor list is one of the most useful documents in the industry. It is also one of the least usable, because it is a flat alphabetical list with inconsistent categories.

This post is my attempt to fix that for 2026. I went through every exhibitor at three shows and sorted them into one catalog, organised around a single question: is this company someone I would buy from, someone who would buy from me, or part of the ecosystem around both?

• SEMICON Taiwan 2026, 2 to 4 September, Nangang Exhibition Center, Taipei (1,284 companies in the catalog)
• SEMICON India 2026, 17 to 19 September, Yashobhoomi, New Delhi (542 companies)
• SEMICON West 2026, 13 to 15 October, Moscone Center, San Francisco (836 companies)

After merging companies that exhibited at more than one show, that is 2,379 unique exhibitors. 215 of them are at two of the shows and 34 at all three. Nobody has been left out: companies that do not fit a supplier or customer chapter are in their own groups further down.

How I built it

All three shows publish their exhibitors on SEMI's expo directory. I collected every exhibitor's booth page and pulled out the company name, country, website, the product categories they ticked and their overview text. Taiwan came from the full exhibitor list. India's exhibitor list page was broken at the time, so I used the floor plan instead, which lists every booth. West came from its floor plan as well. West has not actually happened yet as I write this (it opens on 13 October), so its list is the floor plan as it stood in early October, and any late bookings will be missing.

Each company was then placed in exactly one chapter, based on what it mainly sells. I tried letting companies appear in every chapter they ticked, but some exhibitors tick fifteen categories and the result was useless, so it is one primary chapter per company. Classification started from the categories each exhibitor chose, and I then corrected a few hundred by hand where the self-reported categories were misleading. For example, a vacuum pump maker that also ticks "chemicals" belongs with vacuum, not chemicals.

Shows used different category wording (West's taxonomy is very different from Taiwan's), so the same company can be described slightly differently depending on where it exhibited. When a company appeared at several shows, I kept the description from the most detailed listing.

Some honest caveats:

• The "Based in" column is the country on the exhibitor record, which is often the local subsidiary rather than the headquarters. That is why you will see THK or Pfeiffer listed under Taiwan.
• Several of the biggest names (TSMC, ASE, ASML in Taipei) do not appear in the Taiwan online directory even though they were at the show. If they were not in a directory, they are not here.
• Subsidiaries are kept as separate rows when they exhibited separately, for example Ebara Corporation and Ebara Technologies, because they are different sales contacts.
• 96 Taiwan exhibitors published no product information at all. They are listed in the last chapter rather than guessed at.
• Links go to the website the exhibitor gave SEMI. A few were malformed and have been left unlinked.

How to read the tables

Each chapter has one row per company, with four columns: the company (linked to its website), where it is based, what it offers (at most two items) and which show(s) it was at. TW is Taiwan, IN is India and W is West. Chapters starting with S are suppliers (things that go into a tool), chapters starting with C are customers (people who build or run tools) and chapters starting with E are the wider ecosystem. This replaces a much smaller supplier list I used to keep by hand.

Chapter overview

Suppliers

These are the companies selling the components, subsystems, materials and services that go into building a tool or a fab. For an EFEM or VTM builder, S1 to S9 are the core bill of materials: robots and load ports, motion, vacuum, gas handling, RF power, heaters, chamber parts, FFUs and sensors.

S1. Wafer handling, robots, EFEMs, load ports and AMHS

S2. Motion, drives and mechanical components

S3. Vacuum pumps, valves and components

S4. Gas and fluid handling

S5. Power, plasma, RF and light sources

S6. Thermal components

S7. Chamber parts, quartz, ceramics and coatings

S8. Cleanrooms, FFUs, HVAC and contamination control

S9. Sensors, instruments, electrical and controls

S10. Software, SECS/GEM and IT

S11. Water, exhaust and sub-fab

S12. Distributors, trading, contract manufacturing and engineering

S13. Process materials, gases and chemicals

S14. Packaging and test consumables
