Alarm Notification Software For Semiconductor Facilities
SeQent routes tool-down, process-excursion, and cleanroom alarms from MES, SCADA, and BMS to the right engineer in seconds, with tool ID, lot, and process-step context.

Difficulties Facing the Semiconductor Industry
One tool fault during a critical step puts every wafer in process at risk, and the recovery clock starts long before production resumes.
A one-hour unplanned outage at a leading-edge fab running 60,000 wafer starts a month represents roughly $2 million to $5 million in lost production value, before scrapped lots and re-qualification costs. A 24-hour outage approaches $50 million to $100 million in combined impact.
Bringing a process tool back to spec after an unplanned shutdown takes hours, sometimes days. The minutes between an alarm firing and an equipment engineer responding are where re-qualification time is actually decided.
Every cleanroom entry adds particle risk and ESD exposure. Engineers need to see what’s happening at the tool and respond from outside the gowning envelope whenever possible, not run in for every alarm that fires.
Fab Alarm Management Built For Tool-Level Response
Connect SeQent to your existing tool monitoring, MES, and facility systems. Route alarms with the context engineers need. Document the full response.
Tool-Down And Process Excursion Alerts With Full Context
When a process tool faults or an in-flight step drifts out of spec, SeQent fires the alarm with tool ID, recipe, current step, and the affected lot attached. Equipment engineers don’t have to cross-reference an MES screen to know which lot they’re trying to save.
- Etch, deposition, lithography, CMP, and metrology tool alerts
- Vacuum, gas, and abatement subsystem fault routing
- Tool ID, recipe, step, and lot ID embedded in every alarm
- Severity-based escalation tuned to process criticality
- Configurable suppression and rationalization to reduce nuisance alarms
Cleanroom Alarm Notification That Keeps Traffic Out
Route detailed alarms to equipment engineers, facilities teams, and process engineers outside the cleanroom envelope, while visual andon and LED displays inside give operators at-a-glance status. The right people get the full picture without breaking gowning protocol or adding particle risk.
- Detailed alerts routed to engineering and facilities outside the cleanroom
- Andon, LED, and digital displays for in-bay status visibility
- BMS integration for environmental monitoring (HVAC, differential pressure, particle counts)
- Multi-bay, multi-module, multi-fab visibility from a single platform
- Role-based routing across equipment, process, and facilities teams
Native Integration With Your MES, SCADA, And BMS
SeQent connects to your existing tool monitoring, fab MES, and facility BMS, with no rip-and-replace. Every alarm is logged from trigger through escalation to acknowledgment and resolution, giving equipment engineering, process, and continuous improvement teams the data they need for root-cause review.
- Rockwell FactoryTalk, PlantPAx, RSView (certified Technology Partner)
- AVEVA System Platform, InTouch, PI System
- Velotic Proficy CIMPLICITY and iFIX (formerly GE Vernova)
- Aptean Activplant MES for shop-floor execution
- BMS, environmental monitoring, and tool subsystems via OPC UA, DA, HDA, Modbus, and Ethernet/IP
- Full audit trail of every alarm, escalation, and acknowledgment for RCA review

Regions Covered
One consistent notification architecture spans six regions, from the United States and Europe to the Middle East and Asia Pacific.
The criticality of timely delivery of gases and chemicals utilized in semiconductor production and reliable, clean power led Company C to deploy dual SeQent servers for almost every manufacturing system. This architecture ensures timely notification the second an event occurs that may impact production. Loss of one or more of these process inputs can have a substantial negative impact on a cleanroom environment with significant financial expense to recover.

Common Semiconductor Alarming Questions
A semiconductor alarm notification system monitors process tools, MES, SCADA, BMS, and fab subsystems for alarm conditions and routes alerts to engineers, equipment maintenance, and facilities teams on the devices they use. It enforces escalation rules so tool-down events, process excursions, and cleanroom deviations reach the right responder in seconds, with tool ID, lot, and process step context attached, and a full audit trail of the response.
SeQent integrates with Rockwell Automation (FactoryTalk, RSView, PlantPAx), AVEVA (System Platform, InTouch, PI), Velotic Proficy (CIMPLICITY, iFIX, formerly GE Vernova), and Aptean Activplant MES. For fab-specific tool monitoring, facility BMS, and environmental systems, SeQent connects through OPC UA, OPC DA, OPC HDA, Modbus, and Ethernet/IP. SeQent has long-standing deployments in leading semiconductor manufacturing environments.
SeQent routes tool-down alerts from MES and equipment monitoring systems to equipment engineers in seconds, with tool ID, recipe, and recent state attached. Automatic escalation reaches the next responder when the primary engineer does not acknowledge, and every event is logged from trigger to resolution. Faster acknowledgment shortens the gap between fault and intervention, which is where tool re-qualification time is actually decided.
Yes. SeQent routes detailed alarms to engineers and facilities teams outside the cleanroom envelope on radios, mobile devices, and engineering workstations. Visual andon and LED displays inside the cleanroom give operators at-a-glance status without requiring detailed interactions on equipment HMIs. This keeps cleanroom traffic down while preserving fast response.
A one-hour unplanned outage at a leading-edge fab running 60,000 wafer starts per month represents approximately $2 million to $5 million in lost production value, plus any in-process lots scrapped and the labor required to recover and re-qualify the affected tools. A 24-hour outage at the same fab can approach $50 million to $100 million in combined direct and indirect impact, according to industry analysis.
