Reticle / Mask Particle Detection System PR-PD2HR

Reticle / Mask Particle Detection System, PR-PD2HR

The HORIBA PR-PD2HR Particle Detection System inherits it's high-performance functions from the reticle/mask particle detection PD series which is proud of its high availability and long-term stability. At the same time also increasing the S/N ratio by more than three times and dramatically improving operating sensitivity.

Segment: Semiconductor
Division: Metrology
Base product
Manufacturing Company: HORIBA, Ltd.
  • S/N ratio increased by more than 3x. Dramatically improved operating sensitivity
  • Advanced reticle measurement
  • Substantially reduces the initial costs required for inspections. Increases the number of reticles measured, by dramatically reducing inspection times.
