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.
