Why OT/IT Alignment Matters in Semiconductor

As fabs scale throughput and autonomy, every second of uptime counts; network downtime, flat architectures, and blind spots can jeopardize yield, AMHS traffic, and critical facility controls. Moxa helps you connect, secure, and manage the entire path from tool‑level edge to core so data flows securely and predictably across your fab, enabling increased uptime with resilient Ethernet topologies and fast fault recovery, reduced cyber risk through security‑hardened networking and centralized policy control, and accelerated OT/IT convergence by standardizing connectivity and observability across sites.

Why Moxa?

  • #1 in Serial‑to‑Ethernet with a broad portfolio and long‑term roadmap; trusted by OEMs and fabs.
  • 118M+ devices connected worldwide across industrial networks, backed by 35+ years in OT.
  • Long product lifecycles and copy-exact support commitments to reduce redesign risk in validated tools.
  • Secure‑by‑design product development program ensures fab security acceptance requirements are met.

Top Use Cases for Semiconductor Manufacturing

  • Wafer Fabrication Equipment
  • Facility Monitoring & Control Systems (FMCS)
  • Autonomous Material Handling Systems (AMHS)
  • Edge AI Applications
  • Private Cellular (5G) Across the Fab

Wafer Fabrication Equipment

Bridge legacy serial/fieldbus and modern Ethernet; segment traffic; standardize visibility and logging for tool networks.

Facility Monitoring & Control Systems (FMCS)

Hardened switching and routers interconnect gas, chemical, power, water, and HVAC with redundancy, PRP/HSR options, and fine‑grained zoning.

Autonomous Material Handling Systems (AMHS)

High‑availability backhaul and secure wireless clients support reliable vehicle routing and telemetry with low‑latency roaming.

Edge AI Applications

AI at the edge is delivering measurable operational impact inside the fab by moving intelligence closer to machines and processes. With AI‑driven quality inspection, manufacturers can detect defects in real time and accelerate yield improvement cycles without relying on centralized analytics. Local processing of sensor data enables predictive maintenance, helping teams identify faults earlier and significantly reduce unplanned downtime. Edge‑based cybersecurity and segmented networks improve operational resilience and speed recovery from incidents. Together, these use cases show how AI is evolving from a pure analytics tool into a core operational infrastructure for modern manufacturing.
