Molybdenum Substrate Table for MPCVD Systems FAQ
Q1: Why choose molybdenum as the material for the substrate table instead of other metals or graphite?
A1: Molybdenum is uniquely suited for MPCVD systems compared to other materials. It offers superior plasma erosion resistance and extreme thermal stability (withstanding up to 1200°C continuous operation) that outperforms most metals. Unlike graphite, high-purity molybdenum has lower outgassing, ensuring better vacuum integrity (compatible with base pressure ≤ 5×10⁻⁶ Torr) and avoiding particle contamination during deposition. Our Molybdenum Substrate Table leverages these advantages to maintain dimensional stability and consistent performance in harsh MPCVD environments.
Q2: Is the Molybdenum Substrate Table compatible with all MPCVD system models?
A2: Our Molybdenum Substrate Table is designed with broad compatibility in mind, especially optimized for 2.45GHz MPCVD systems. We also offer full customization services, including adjustments to diameter, thickness, surface texture, and mounting interface, to match specific MPCVD system models. Simply provide your system specifications, and we will tailor the substrate table for a perfect fit.
Q3: What is the maximum operating temperature of the Molybdenum Substrate Table?
A3: The Molybdenum Substrate Table supports continuous operation at temperatures up to 1200°C. Thanks to molybdenum’s high melting point and excellent thermal conductivity, it maintains dimensional stability even under extreme thermal cycling, ensuring uniform temperature distribution across the substrate surface—critical for high-quality diamond film deposition and other advanced material growth.
Q4: How long is the service lifespan of the Molybdenum Substrate Table?
A4: The service lifespan depends on operating conditions (e.g., temperature, plasma intensity, and cycling frequency), but our Molybdenum Substrate Table is engineered for long-term use. Its high-purity molybdenum material offers strong wear resistance and chemical inertness in MPCVD environments, significantly reducing replacement frequency. Proper use and maintenance can further extend its lifespan, lowering overall equipment maintenance costs.
Q5: Can the surface finish of the Molybdenum Substrate Table be customized?
A5: Yes. We provide two surface finish options for the Molybdenum Substrate Table: standard precision finish for general applications, and optional mirror polish (Ra ≤ 0.1 μm) for scenarios requiring ultra-smooth surfaces, such as high-precision optical component deposition or quantum technology research. Custom surface textures can also be arranged based on specific process requirements.
Q6: What quality tests does the Molybdenum Substrate Table undergo before delivery?
A6: Each Molybdenum Substrate Table undergoes rigorous quality control to meet MPCVD system standards. Tests include plasma erosion resistance testing, thermal cycling performance verification, vacuum integrity inspection, dimensional accuracy measurement (ensuring ±0.01mm tolerance), and surface finish detection. We also adopt Class 1000 cleanroom packaging to avoid contamination during transportation.
