AES motomation — 20:87:AC (MA-L)

AES motomation holds a single IEEE MA-L block, 20:87:AC, registered to "AES motomation" at 48501 Warm Springs Blvd., Fremont, CA 94539, US. Unlike a bare shell registration, this OUI traces to an identifiable, currently operating company: AES motomation designs and builds cleanroom automation equipment for semiconductor and flat-panel-display fabs — load ports, EFEM/iFEM front-end modules, and wafer-handling robots. Corporate structure appears to be a German parent (AES motomation GmbH) with the Fremont, CA office (AES motomation Inc.) matching the OUI registrant address, plus a Taiwan subsidiary; company sources put its founding around 1998–2000. The company carries a SEMI trade-association membership listing and has exhibited at SEMICON West, alongside D&B, Crunchbase, LinkedIn, and RocketReach profiles that corroborate its existence and industry. Its product line — networked fab-floor equipment controllers running Ethernet/SECS-GEM style interfaces — is a plausible fit for an OUI registration, though no vendor-published source names the 20:87:AC prefix on a specific product. No other OUI block under the exact registrant name "AES motomation" appears in the registry; other "AES"-prefixed registrants (AES Corporation, AES PRODATA, AES DATA INC.) are unrelated companies at different addresses.

Company identity

AES motomation — semiconductor/flat-panel-display cleanroom automation vendor (load ports, EFEM/iFEM front-end modules, wafer-handling robots); German parent AES motomation GmbH, US office in Fremont, CA matching the OUI address, Taiwan subsidiary; founded roughly 1998–2000 [Likely] — https://motomation.com, https://www.linkedin.com/company/aes-motomation-inc, https://www.semi.org/en/resources/member-directory/aes-motomation-gmbh, https://portal2026.semiconwest.org/co/aes-motomation, https://www.dnb.com/business-directory/company-profiles.aes_motomation_inc.0d7417a759b8cabca9ac087e7b575db4.html, https://www.crunchbase.com/organization/aes-motomation, https://rocketreach.co/aes-motomation-inc-profile_b5867a08f6118494

Device type corroboration

product line (load ports, EFEM/iFEM modules, wafer-handling robots) commonly embeds networked Ethernet/SECS-GEM controllers, consistent with holding an OUI, though no vendor source explicitly names the 20:87:AC prefix on a product [Likely] — https://motomation.com

Multiple OUI assignments

none found — only one MA-L block on record under the exact registrant name "AES motomation"; other "AES"-named registrants are unrelated companies at different addresses [Confirmed] — the IEEE MA-L registry

Company substance verdict

identifiable operating company with genuine product/device context, multi-country presence, trade-association membership, and third-party business-directory profiles — not a bare single-OUI shell [Likely] — sources above
