Semiconductor lot excursion review
Trace a lot excursion from process event through engineering review and quality disposition.
Illustrative exception workflow only. It does not control fabrication equipment or replace a qualified MES or QMS.

The problem
What goes wrong today
A process deviation can affect lots, tools and downstream review teams. When the evidence is spread across systems and handoffs, it is hard to see which lots are on hold, who owns the investigation and whether the disposition is recorded.
How it runs on TechAppForce
A day with it, step by step
Amber steps wait in a person's work inbox; everything else moves on its own.
- An event is reportedA process engineer logs an event with its equipment, step, recipe version and supporting evidence.
- Affected lots are linkedThe engineer links the lots requiring review, making their hold status and current owner visible.
- Engineering investigatesThe team records checks and findings on a shared investigation rather than passing notes between shifts.
- Quality records dispositionQuality reviewA quality reviewer checks the evidence and records the lot disposition and any follow-up.
- Exceptions stay reportableThe review pack shows the event, affected lots, evidence, decision and outstanding actions.

- NotifyA reported excursion alerts process engineering and creates a linked review record
- WorkflowAffected lots stay visible in a hold queue until disposition is recorded
- ScheduleA scheduled summary groups open exceptions by product, tool and age
Screens and reports 5
- Lot exception queue with product, process step and hold status
- Investigation form linked to event evidence and affected lots
- Disposition review with decision history and reviewer comments
- Open excursions by severity, process step and review owner
- Lot disposition history for an internal review pack
Who approves, in detail
Engineering records the investigation and recommended disposition. Quality reviews the evidence and decision before the exception is closed; higher-severity events can route to an additional product owner.
