Gasonics A93-038-01 RF Power Supply
Product Description: This unit is a critical internal component or sub-assembly typically used within Gasonics plasma stripping and cleaning systems. It functions as an RF power supply or a matching network component responsible for generating and controlling the radio frequency energy required to ignite and sustain the plasma discharge during the semiconductor manufacturing process.
Technical Specifications:
- Type: Radio Frequency (RF) Generator or Matching Network Sub-assembly
Detailed content
- Frequency: Typically 13.56 MHz (Standard for plasma processing)
- Power Output: Variable, dependent on specific system configuration (often 300W to 1000W range)
- Impedance: 50 Ohms (Standard)
- Cooling Method: Forced Air or Water Cooling (internal to the chassis)
- Interface: Analog or Digital control signals for power level and tuning
Functional Features:
- Precise Power Control: Delivers stable RF power to ensure uniform plasma density.
- Impedance Matching: Automatically or manually matches the generator output to the plasma load to minimize reflected power.
- High Reliability: Designed for continuous operation in cleanroom environments.
- Interlock Integration: Connects with system safety interlocks to prevent operation if cooling or gas flows are incorrect.
Application Scenarios:
- Photoresist Stripping: Removing hardened photoresist from silicon wafers after etching or ion implantation.
- Plasma Cleaning: Cleaning chamber components or wafer surfaces to remove organic contaminants.
- Surface Activation: Modifying surface properties of materials to improve adhesion in packaging processes.
- Semiconductor Fabrication: Used in backend packaging and MEMS manufacturing lines.
