FAQs

Do you make photomasks for excimer laser machining?

Stepper Wavelengths

In addition to making photomasks for use with the wavelengths of visible light, we can also make photomasks suitable for using with i-line (365nm), 248nm and 193nm Deep UV wavelengths.

When ordering photomasks for smaller wavelengths, Quartz glass should always be used.

Also, if a pellicle is required, it is good practice to identify the wavelengths, for which the pellicle should be optimized.
