MKS ASTRON 2L (also known as the series) is an industrial-grade remote plasma source designed primarily for semiconductor manufacturing, specifically for cleaning chemical vapor deposition (CVD) process chambers Operational Summary

The ASTRON 2L functions as a low-field toroidal RF plasma source MKS Instruments

. It generates high fluxes of reactive gas-phase radicals (like atomic fluorine from cap N cap F sub 3 ) to remove residues from chamber walls

. This "remote" method is widely preferred in industry because it reduces damage to the expensive components inside the main CVD chamber compared to in-situ cleaning MKS Instruments Key Technical Specifications Model Number AX7651-2 (ASTRON 2L) Approximately 52 kg (115 lbs) Primary Use Chamber cleaning and reactive gas production MKS Instruments Cleaning Agent Typically Nitrogen Trifluoride ( cap N cap F sub 3

High-flow water cooling is generally required for these high-power RF units Springer Nature Link Safety & Maintenance (from the Manual) Pressure Warning:

The unit and its internal gas-handling components are intended strictly for vacuum use

. Subjecting the ASTRON 2L to pressures above atmospheric can lead to permanent damage or dangerous gas leaks Chemical Hazard: Since the device frequently uses cap N cap F sub 3 , which is colorless and has a very faint odor, the safety manual

stresses the mandatory installation of sensitive gas detectors Transport Geometry:

To maintain cleaning efficiency, the transport tube connecting the ASTRON to the process chamber must be short and made of materials minimally reactive to fluorine radicals (to avoid losing the cleaning flux to the tube walls) MKS Instruments Industry Reputation

The ASTRON line is considered a standard for high-throughput semiconductor manufacturing

. It is known for significantly extending the service life of CVD chambers, though the plasma source itself is a consumable component with a finite lifetime due to internal surface damage over time MKS Instruments

The MKS Astron 2L is a professional-grade, high-capacity ozone delivery system. It is primarily used in semiconductor manufacturing and industrial water treatment. Because this is a precision instrument, following the manual is critical for both machine longevity and operator safety. 🛠️ System Overview

The Astron 2L (and its sibling, the Astroni) uses a silent corona discharge to convert oxygen into high-concentration ozone. Flow Capacity: Up to 2 liters per minute (Lpm).

Ozone Output: High-concentration yields, typically up to 20% by weight.

Cooling: Requires active water cooling to prevent thermal runaway.

Controls: Digital and analog interfaces for easy integration. ⚠️ Safety Protocols

Ozone is a powerful oxidant. Before powering on the unit, ensure the following are in place:

Leak Detection: Always use an ambient ozone monitor in the room.

Proper Venting: Never exhaust ozone directly into the workspace; use an ozone destruct unit. mks astron 2l manual

Material Compatibility: Ensure all downstream tubing is ozone-compatible (e.g., Teflon/PFA, 316L Stainless Steel).

Electrical Grounding: The chassis must be grounded to prevent static discharge. 🚀 Installation & Setup

According to the technical manual, setup follows these specific steps: 1. Plumbing Connections Gas Inlet: Connect ultra-high purity (UHP) Oxygen. Gas Outlet: Use stainless steel compression fittings.

Cooling Water: Connect the "Cooling In" and "Cooling Out" ports. Use deionized (DI) water or chilled process water. 2. Electrical Wiring

Connect the primary AC power source (refer to your specific model label for voltage requirements).

Plug in the communication cable (RS-232, Profibus, or Analog) to your controller. 3. Gas Requirements Feed Gas: Oxygen (99.99% purity or better).

Dopant: A small amount of Nitrogen (N2) or Carbon Dioxide (CO2) is often required (approx. 50–100 ppm) to stabilize the ozone production. ⚙️ Operation Guidelines To produce ozone, follow this sequence: Start Cooling: Turn on the water flow first.

Purge Gas: Run oxygen through the cell for 5 minutes to clear moisture.

Apply Power: Activate the RF generator via your control interface.

Monitor Pressure: Ensure the internal pressure stays within the 10–30 psig range (standard for most 2L models). 🔧 Maintenance & Troubleshooting To keep the Astron 2L running at peak efficiency:

Check Flow Rates: If ozone concentration drops, check for a clogged inlet filter.

Inspect Seals: Replace O-rings annually to prevent gas leaks.

Monitor Temperature: If the unit shuts down unexpectedly, check your cooling water temperature and flow rate. Are you dealing with a specific error code? Do you need help integrating it with a PLC?

This system is designed as a self-contained, "lid-mount" unit that generates reactive gas radicals—like atomic fluorine from cap N cap F sub 3

—at the point of use to maximize cleaning efficiency and reduce chamber damage. ResearchGate Key Technical Specifications

The MKS Astron 2L (Part Number AX7651-2) is a remote plasma source (RPS) commonly used in semiconductor manufacturing for cleaning process chambers. Manuals for the Astron series generally cover safety protocols, installation, and technical operation for atomic fluorine generation. Core Functionality

The Astron 2L is an electrode-less, transformer-type discharge system.

Purpose: It generates atomic fluorine radicals to react with and remove waste deposits from the interior walls of CVD (Chemical Vapor Deposition) or FPD (Flat Panel Display) process chambers.

Mechanism: Uses Low-Field Toroidal plasma technology to dissociate gases like NF3cap N cap F sub 3

efficiently while maintaining low electric fields to prevent reactor wall damage.

Key Advantage: By generating reactive species remotely, it reduces wear and tear on the process chamber compared to in-situ RF methods. Technical Specifications

Based on related Astron models (AX7680/AX7670) often detailed in similar manuals: Performance: Typically achieves >95% dissociation of NF3cap N cap F sub 3 gas. Physical: Dimensions are roughly with a weight of approximately 38 kg (84 lbs). Gas Handling: Requires (Argon) for initial ignition; after ignition, NF3cap N cap F sub 3 can be added and Argon removed.

Cooling: Requires a water cooling flow of roughly 1.5 to 2.0 gpm at temperatures below 30∘C30 raised to the composed with power C . Critical Safety & Maintenance

The manual contains essential warnings for handling these high-power reactive gas systems:

Vacuum Integrity: The unit must only be used under vacuum. Subjecting it to pressures above atmospheric can permanently damage the generator or cause hazardous gas leaks. Toxic Gas Exposure: Because NF3cap N cap F sub 3

provides little warning of its presence (odorless at low concentrations), manuals mandate the use of sensitive detectors in the installation area.

Maintenance: Standard maintenance involves monitoring output voltage at zero pressure. Never attempt to clean the internal sensor, as this voids the warranty and can destroy the unit's calibration.

Chapter 8: Replacing the Astron 2L – When to Upgrade

The manual’s last section often references product evolution. MKS now recommends the PFR 400 or MicroPirani 925 for newer systems. However, the Astron 2L remains popular for legacy systems due to its low cost and simple analog output.

Error 2: Unstable or noisy readings

  • Probable cause: Contamination in the cold cathode gauge (common in sputtering systems).
  • Manual fix: Run a degas cycle. Press and hold the DEGAS button for 3 seconds. The controller will apply high voltage without current limiting for 5 minutes. Warning: This reduces gauge life if overused.

Degas Frequency

The manual specifies: Degas only when pressure is below 1 x 10⁻⁵ Torr. Degassing at higher pressures will cause arcing and permanent damage. One 5-minute degas per week is sufficient for clean systems.

1. First Steps: Unboxing and Assembly

Unlike smaller, open-air wash and cure stations, the Astron 2L comes partially disassembled to protect the motor and LED array during shipping.

  • The Lid: Carefully remove the protective film from the acrylic lid. This lid blocks harmful UV light, so ensure it is free of deep scratches that could compromise safety.
  • The Turntable: Locate the metal turntable platform. It usually attaches via a magnetic coupling or a simple gravity-fit mount on the central spindle. Ensure it sits flat to prevent your resin vat or prints from sliding off during rotation.
  • Power: Connect the provided power adapter. The Astron 2L requires a stable power source to maintain consistent LED output.

4.4 Reading the Analog Meter

  • Scale: 10⁻³ to 10⁻⁹ Torr (logarithmic).
  • Multiply the scale reading by the multiplier (X1, X10, etc. if equipped with an expander option).

Part 7: Maintenance & Spare Parts (From the Manual’s Appendix)

Unlike modern digital controllers, the Astron 2L requires periodic analog upkeep.
