Ibsen offers Phase mask cleaning, NFH technology services and grating foundry services
Phase masks may become contaminated during use – an effective cleaning process is important in ensuring longest possible lifetime of the Phase mask. Ibsen offers Cleaning Services for your Phase masks, optionally with an extensive evaluation of the Phase mask defect level before and after cleaning.
Ibsen offers grating foundry services for high quality grating exposure on your wafers. We can offer basic interferometric 2-beam exposure (the patterning technology behind our 0.01 nm period accuracy Phase masks), or for higher volumes holographic/lithographic stepper technology.
