Core Semiconductor Applications

From vacuum-chamber surfaces to probe-tip geometry, two areas where tooling precision directly determines equipment performance

  • UHV / EHV Chamber
    Components

    Ultra-precision machining support for vacuum components, where surface condition, dimensional accuracy, and contamination control achieve the ultimate vacuum performance.

    • Ultra-smooth Surface Roughness
    • Dimensional Accuracy
    • Consistent Finish
  • Semiconductor
    Test Probes

    Precision tooling for probe-tip geometries and conditions that demand fine tip-feature control, consistent contact characteristics, and repeatable dimensional performance in probe cards.

    • Fine Tip Geometry
    • Execellent Lifespan
    • Repeatable Contact Performance
