Bottlenecks and Idle Equipment from Poor Fab-Wide Scheduling
Definition
In semiconductor fabs, bottlenecks arise from process loops, low-capacity high-cost machines, and WIP flow controls like kanbans that block high-priority wafers. This leads to idle equipment, non-linear wafer flows, and excessive manual interventions such as hundreds of ad hoc control rules weekly to manage queues and holds. Pre-optimization, fabs suffer recurring capacity loss due to toolset-level scheduling limitations that ignore multi-step future predictions.
Key Findings
- Financial Impact: $Multi-million annual throughput and cycle time losses (pre-optimization baseline)
- Frequency: Daily
- Root Cause: Fragmented toolset scheduling without fab-wide visibility, failing to predict wait/cycle times across multiple steps and redirect flows.
