Pilot Production

Pilot Production is the transitional manufacturing phase between process development and full volume production — running small quantities of product wafers through the production line to validate the process, qualify the product, and build initial customer samples before committing to high-volume manufacturing.

Pilot Production Characteristics

• Volume: Typically 10-100 wafer starts per week — small enough to manage risk, large enough to generate meaningful data.
• Process Freeze: Core process parameters are frozen — only fine-tuning and optimization allowed.
• Qualification: Reliability testing (HTOL, ESD, latch-up) and customer qualification during pilot phase.
• Yield Target: Demonstrate yield trajectory — yield may not be at mature levels but must show improvement trend.

Why It Matters

• Validation: Confirms the process works in a production environment — not just in the lab.
• Customer Samples: Provides functional samples for customer qualification and design-in decisions.
• Manufacturing Readiness: Identifies production issues (equipment capacity, recipe stability, metrology coverage) before ramp.

Pilot Production is the dress rehearsal — small-scale production to validate process, qualify products, and prepare for high-volume manufacturing ramp.
