Chemical Etch TGV Processing for Large-Format Glass Core Substrates

Chemical etching of high-aspect-ratio through-glass vias (TGV) on panels up to 510x515mm with diameters from 20µm, multiple shapes, and integrated Cu plating for semiconductor interposers.

Problem solved

Scalable formation of dense vertical interconnects in large glass panels for cost-effective glass-core substrates used in co-packaged optics and high-density AI packaging.

Application contexts

  • glass core substrates
  • glass interposers
  • semiconductor packaging

Technical principle

Chemical etching to create vertical, hourglass or tapered vias in various glasses, followed by conformal or filling copper plating with high adhesion.

Typical use cases

  • Large panel TGV for CPO substrates
  • high-aspect via interposers
