Structuring of TCO/ITO Layers With the UV Laser

Transparent conductive oxides (TCOs) are electrically conducting materials that are applied in thin layers to transparent substrate materials. ITO layers are especially common. They can be structured very selectively with the UV laser.

Finest insulation on invisible layers

Advantages of Laser Structuring of TCO/ITO Layers

  • Absolutely invisible structuring of transparent ITO coatings
  • No damage to the substrate material
  • Flexibility: Layout can be changed at any time
  • Structuring directly from CAD data
  • Reduction of technological steps (no resist application, no etching)
  • Ultrafine structures with <50 µm traces/spaces possible
  • High positioning accuracy through registration of fiducial marks or other visible marks
