- Model Number: B-11002-02 (Rev 00F)
- Product Series: Spectrum Series
- RF Output Power: 11 kW (Kilowatts)
- Frequency Range: 1.8 MHz – 2.0 MHz
- Revision Status: Rev 00F
- Application: Semiconductor etching, CVD/PECVD, plasma deposition, and thin-film processing. The MKS ENI B-11002-02 is a high-performance, solid-state RF plasma generator from the renowned Spectrum series, delivering a robust 11kW of output power across a precise 1.8 to 2MHz frequency range. Engineered specifically for demanding semiconductor fabrication and advanced thin-film deposition environments, this Revision 00F model ensures exceptional power stability, rapid plasma ignition, and superior reliability under dynamic load conditions, making it an essential component for high-yield, continuous manufacturing processes.
Comparison with Similar Models
The B-11002-02 stands out from other models in the MKS ENI Spectrum lineup due to its specific power-to-frequency tuning and revision enhancements:
- Power Output Advantage: Unlike standard 3kW or 5kW Spectrum models (such as the B-3002 or B-5002 series), the B-11002-02 delivers a massive 11kW, designed for high-density plasma chambers that require deeper penetration and faster deposition/etch rates.
- Frequency Tuning: While many standard RF generators operate at a fixed 13.56MHz, this unit operates in the lower 1.8-2.0MHz band, which provides higher ion energy—ideal for specific dielectric etch and bias applications where standard high-frequency generators fall short.
- Revision 00F Upgrades: Compared to earlier revisions (like Rev 00A or 00C), the Rev 00F features upgraded internal cooling geometry and modernized solid-state power amplifier (SSPA) modules, offering better thermal dissipation and a reduced risk of RF arc-back damage.
Product Operation Tips
- Cooling and Water Flow Monitoring: Because this unit outputs a powerful 11kW, ensuring adequate water cooling is critical. Always verify that the chiller flow rate, water pressure, and temperature meet MKS specifications before striking the plasma. Never operate the unit if the water temperature exceeds the maximum rated threshold.
- Impedance Matching Network (Matchbox) Calibration: To prevent reflected power from damaging the RF generator, ensure that the associated matching network is properly calibrated to the 1.8-2.0MHz frequency band. Monitor the Voltage Standing Wave Ratio (VSWR) closely during initial startup; high reflected power will trigger automatic safety folds.
- Interlock and Safety Checks: Always verify that all safety interlocks (such as enclosure switches and vacuum pressure interlocks) are properly integrated into your tool’s control system. Never attempt to bypass the RF output interlocks while the system is energized, as high-power RF can cause severe burns and electromagnetic interference.
