Key Features

  • High-Density Inductively Coupled Plasma

    Generates a high-density ICP to deliver rapid, uniform etch rates with strong ionization, enabling precise pattern transfer and improved selectivity across a wide range of semiconductor and material chemistries.

  • Dual-Chamber Load-Lock Design

    Separate pre-vacuum (load lock) and reaction chambers minimize contamination and exposure, improving throughput and yield by allowing safe wafer transfer without venting the process chamber.

  • Independent RF Bias Control

    Separate ICP and bias RF sources allow independent control of plasma density and ion energy, giving precise etch profile control, reduced damage, and adaptable recipes for various materials.

  • Advanced Gas Flow Management

    Multi-channel gas delivery with mass flow control and accurate metering enables repeatable process chemistry, fast recipe switching, and fine control of etch selectivity and uniformity across substrates.

  • Integrated Thermal and Backside Control

    Backside helium control combined with cooling system maintains uniform wafer temperature and prevents overheating, improving process stability and critical dimension control during long etch runs.

  • Automated Handling and Software Control

    Automated wafer transfer and intuitive process software provide recipe management, real-time monitoring and diagnostics, simplifying operation and reducing operator intervention for consistent production.

Plasma Cleaning Process

  • Plasma Generation

    Process gas is energized and converted into a reactive plasma containing ions, electrons, and radicals.

  • Plasma–Surface Interaction

    High-energy plasma species reach the material surface and interact with contaminants at the molecular level.

  • Chemical Reaction

    Reactive ions and radicals break down organic residues and surface contaminants through controlled chemical reactions.

  • Volatilization

    The reaction products are converted into volatile compounds and enter the gas phase.

  • Removal from Surface

    Gaseous by-products desorb from the surface and are evacuated, leaving a clean, activated material surface.
