Gasonics 04630-004
Product Description: This part number identifies a specific RF Match Network or Impedance Matching Circuit used in Gasonics plasma systems. The match network is critical for transferring maximum power from the RF generator to the plasma load, ensuring stable ignition and efficient operation.
Technical Specifications:
- Component Type: RF Impedance Matching Network
- Frequency Range: 13.56 MHz (± tuning range)
Detailed content
- Power Handling: Up to 5000 Watts (forward and reflected power)
- Tuning Elements: Motorized vacuum variable capacitors
- Connectors: 50-ohm coaxial input/output with water-cooled N-type or APC-7 connectors
- Control Interface: Analog or digital communication with the system controller
Functional Features:
- Automatic Tuning: Rapidly adjusts capacitance to maintain a 1:1 VSWR (Voltage Standing Wave Ratio) during process transitions.
- Reflected Power Protection: Minimizes reflected power to protect the RF generator and transmission lines from damage.
- Process Stability: Ensures consistent plasma density and ion energy, which is vital for repeatable etch or strip rates.
- Water Cooling: Integrated cooling channels to handle thermal loads during high-power operation.
Application Scenarios:
- Plasma Etching: Used in dielectric and metal etch tools.
- PECVD: Used in Plasma Enhanced Chemical Vapor Deposition systems for thin film coating.
- Sputtering: Used in physical vapor deposition (PVD) tools.
- System Maintenance: Replacement unit for upgrading older Gasonics RF power supplies to improve process stability.
