Gasonics 15698-02 RF Generator
Introduction:
The Gasonics 15698-02 is an RF (Radio Frequency) power supply module or a specific sub-assembly within a larger generator system. This component is responsible for generating the electromagnetic energy required to ignite and sustain plasma in process chambers. It is designed for high reliability and precise power delivery in semiconductor manufacturing.
Technical Specifications:
- Type: Solid State RF Generator or Tube-Based (Tetrode/Triode)
- Frequency: 13.56 MHz (Standard) or 2 MHz – 60 MHz (Tunable)
Detailed content
- Output Power: 500W to 3000W (Typical range)
- Output Impedance: 50 Ohms (Nominal)
- Input Power: 208VAC or 480VAC, 3-Phase
- Cooling: Forced Air or Water Cooling
- Control Interface: RS-232, RS-485, Ethernet, or Analog (0-10V)
Functional Features:
- Automatic Impedance Matching: Interfaces with a match network to minimize reflected power (VSWR).
- Plasma Ignition: High-voltage strike circuit for reliable plasma ignition at low pressures.
- Arc Detection: Fast-acting protection circuits to suppress RF arcing and prevent damage.
- Modulation Capability: Supports analog or digital modulation for pulsed plasma processes.
- Soft Start/Stop: Gradual power ramping to protect the generator and load.
Application Scenarios:
- Reactive Ion Etching (RIE): Providing energy for ion acceleration and dissociation of etchant gases.
- Plasma Enhanced CVD (PECVD): Generating plasma to lower deposition temperatures.
- Sputtering (PVD): Creating high-density plasma for target material ejection.
- Photoresist Ashing: High-power oxygen plasma for resist stripping.
- Surface Treatment: Plasma cleaning or activation of wafer surfaces.
