Application in PECVD Equipment
Our high-voltage doorknob capacitors provide stable high voltage for Plasma-Enhanced Chemical Vapor Deposition (PECVD) equipment, essential for semiconductor, photovoltaic, and optical coating industries. These capacitors enable low-temperature deposition of high-quality thin films by maintaining stable, uniform plasma through efficient RF power supply performance.
Technical Challenges Addressed
  • Impedance Matching: Efficient power coupling to dynamically changing plasma loads
  • High RF Power Handling: Withstands electrical stresses from high frequency and voltage
  • Thermal Management: Minimizes heat accumulation from dielectric and electrode losses
  • Long-term Stability: Prevents capacitance drift that affects deposition rate and film quality
Solution: High-Q, Low-ESR Doorknob Capacitors
  • Efficient Power Transfer: Low ESR minimizes heat generation with high RF currents
  • Thermal Stability: Temperature-compensated ceramic dielectric maintains stable capacitance
  • High Reliability: Rugged construction ensures long service life in demanding RF conditions
Customer Benefits
  • Improved film quality and consistency through stable impedance matching
  • Increased productivity and yield with reduced process interruptions
  • Lower operating costs from reduced energy consumption and maintenance
Our high-voltage doorknob capacitors serve as the "impedance harmonizer" for PECVD equipment, enabling precise atomic-level deposition for superior thin film production.
