- Design PECVD double reaction zone: increase the Monomer dissociation rate and increase the film thickness uniformity, and shorten the process time.
- Optimized exhaust system: shorten the length of the pipeline, and match the well-known brand pump to achieve the best exhaust effect.
- No valve stem exposed to vacuum: Eliminate the adhesion of contaminants to the surface of the valve stem, reducing the chance of gas leakage.
- Complete process parameters and historical records, so that users can access historical data and analysis.
- Bilingual interface, image-based operation, easy to use.
- Independent safety loop power supply, multiple sets of emergency stop switch settings, improve personnel operation safety.
