Reticle/Mask Particle Detection System

Inspection object

Particles on reticle/mask with or without pellicle

Principle

Laser scattering method

Inspection time

Approx. 7 min/2 surfaces (5 inch reticle), Approx. 7 min from inspection start (switch ON) to test result display for two surface (5 inchs) inspection
* High throughput model specific to the glass/pellicle (approx. 4 min. for two surface inspection) is also available.

Detectable particle size

Pattern surface: 0.5 µm, Glass surface: 5.0 µm, Pellicle surface: 10.0 µm (* PSL equivalent)

Reticle size

5, 6 or 7 inch (Please specify when ordering.)

Reticle cassette (Please specify when ordering)

Applicable to the HORIBA standard cassette for 5, 6, 7 inches as well as stepper cases unique to individual maker for 5, 6 inches. (Single size of reticle and cassette handling is the standard. Contact us as to the multiple cassette handling system.)
