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 five main shows, then topped it up from eight more SEMICON directories and SEMI's member directory (details below), 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)
• SEMICON Europa 2026, 10 to 13 November, Messe München, Munich (644 companies)
• SEMICON Japan 2026, 9 to 11 December, Tokyo Big Sight, Tokyo (825 companies)

After merging companies that exhibited at more than one show, that is 3,188 unique exhibitors. 645 of them are at more than one show and 17 at all five. I have also folded in 30 companies from my own older supplier list that did not exhibit at any of the five.

To make the catalog as complete as possible, I then added every company not already listed from four more 2026 shows (SEMICON Korea, SEMICON Southeast Asia, SEMICON Vietnam and SEMICON China) and from the 2025 editions of Taiwan, India, Europa and Japan. That added 2,554 companies. Finally, I went through SEMI's own member directory (about 3,000 members) and added the 1,019 members that were not already listed, tagged SEMI. That brings the catalog to 6,791 companies. Companies that were already in the catalog also picked up the KR, SEA, VN and CN tags where they exhibit at those shows. Two caveats: the 2025-only entries (tagged TW25, IN25, EU25 and JP25) may not be exhibiting this year, and the Korea, Southeast Asia and China directories publish much less product detail, so about 1,150 of the new entries sit in the last group with no product details. The SEMI members were sorted into chapters by keywords in their member-directory description, so treat their placement as a rough guide; about 150 of them are in the last group because their description did not say what they make. 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 of these 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. The same goes for Europa, which opens on 10 November: its list is also taken from the floor plan in early October. Japan, which opens on 9 December, is the same again. Its booth pages are in Japanese by default, so I used the English versions for names and descriptions.

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. Europa was added later and I handled it differently: when the European arm of a company that was already listed exhibited (VAT Deutschland, Ebara Precision Machinery Europe, Canon Europa and so on), I tagged the existing row with EU instead of adding a European duplicate.
• Japan was handled the same way: 349 Japan exhibitors were already in the catalog (often as the parent company or a local subsidiary) and were tagged JP, and the other 476 were added as new rows.
• 96 Taiwan exhibitors, 69 Europa exhibitors and 45 new Japan 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, EU is Europa, JP is Japan, KR is Korea, SEA is Southeast Asia, VN is Vietnam and CN is China (all 2026). TW25, IN25, EU25 and JP25 mark companies found only in last year's edition of that show, SEMI marks a SEMI member that I did not find at any of these shows, and 2023 marks a company from my older hand-made supplier list. 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, and everything on that list is now in here.

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
