Glass spacers | Interposers

Our produced Glass Spacers (Interposers) are suitable for 2.5D / 3D integration and wafer-level bonding with semiconductor substrates for MEMS, sensors, analytical chips, or other functional devices.

WOP offers high surface quality glass wafers densely packed through holes that require none or minimum post-processing before being used in your production process. We offer prototyping and production for your individual designs.

We ensure:

  • Ultra-high precision and quality
  • Various types of glass
  • Small feature sizes
  • High aspect ratios unachievable with alternative technologies
