Key Features

  • High-Rate Photoresist Stripping

    Provides stable plasma ashing performance for controlled photoresist removal within standardized semiconductor process workflows.

  • Controlled Cleaning for Sensitive Films

    Enables precise process window control to protect sensitive layers while maintaining consistent stripping performance.

  • Recipe-Based PLC Operation

    Uses PLC and touchscreen control for recipe setup, parameter management, and consistent results across shifts.

  • Flexible Gas Chemistry Options

    Works with multiple gas choices and mixed recipes to match different resist types, residues, and film stacks.

  • Improved Coverage on Complex Structures

    Helps treat 3D features and difficult geometries where wet stripping can suffer from diffusion and wetting limits.

  • Cleaner Process With Reduced Chemical Use

    Uses a dry process approach that can reduce reliance on wet chemicals and simplify handling in many lines.

Plasma Cleaning Process

  • Plasma Generation

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

  • Plasma–Surface Interaction

    Energetic plasma species interact with surface molecules and contaminants under controlled vacuum conditions.

  • 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.
