Excessive Rework and Scrap Costs from Uncontrolled Yield Excursions
Definition
Poor yield analysis fails to enable proactive lot holds or rework prioritization, leading to unnecessary processing of low-yield wafers through costly steps. This results in wasted materials, equipment time, and labor on defective products that ultimately fail specs. Industry reports highlight how even small yield improvements via better analytics preserve capacity and reduce these overruns.
Key Findings
- Financial Impact: $Millions per year (yield loss directly equates to monetary value via reduced OEE and material waste)
- Frequency: Daily
- Root Cause: Lack of integrated fault detection and yield management systems for early outlier exclusion and Q-time control
