Cleanroom Certification.
Zero room for delays.
Your $15B semiconductor fab has a 14-day window to rig 120 process tools through the roof opening before cleanroom closure. One tool arrives late, and the $200M EUV lithography system can't be installed until you cut a new opening — adding 6 months and $40M. Your daily report says “tool installation continues in Bay 3.”
POD tracks tool rigging windows, cleanroom certification sequences, and subfab utility coordination in one voice report.
The Challenges of Fab Construction Reporting
Tool rigging window conflicts
A $15B fab has 120 process tools that must be rigged through roof openings before cleanroom closure. Each tool weighs 10-40 tons and requires specific crane configurations, floor loading paths, and utility pre-stubs. Miss the 14-day window, and you cut a new opening for $2M+ and 6 months delay.
Cleanroom classification sequence management
Certification proceeds from ISO 8 to ISO 7 to ISO 5 in sequence. Each step requires prior-step verification, HEPA/ULPA commissioning, and particle count testing. A contamination event at any stage resets the certification clock for that zone.
Subfab-to-fab coordination gaps
Subfab utility trenches, chemical distribution piping, and exhaust systems must be completed and tested before raised floor installation. But subfab and fab are managed by different teams with separate daily reports that never cross-reference.
Particle contamination during construction
Welding, grinding, cutting, and even foot traffic generate particles that can contaminate adjacent cleanroom zones. Without real-time contamination event logging, you discover the problem during certification testing — weeks after the event occurred.
How POD Solves Fab Construction Coordination
Tool delivery vs window tracking
POD maps each tool delivery date against roof-opening schedules, crane availability, and cleanroom closure deadlines. Buffer days are calculated per tool, and alerts fire when any tool is at risk of missing its rigging window.
Classification milestone sequencing
Track ISO classification sequences from subfab completion through raised floor, wall closure, HEPA install, and particle count testing. Delays propagate automatically so you see the cascade before it happens.
Subfab utility coordination
Link subfab utility completion status to fab raised-floor installation readiness. POD shows which fab zones are blocked by incomplete subfab work and calculates the cost of each day of delay.
Contamination event logging
Log every contamination event with timestamp, zone, particle count reading, probable cause, and corrective action. Track whether events push certification milestones and calculate cumulative schedule impact.
