WebApr 16, 2015 · Pellicle dilemma At one time, the industry insisted that EUV masks did not require a pellicle. Used in all optical masks, a pellicle is a thin-film membrane that sits on the reticle and acts as a dust cover. To inspect an EUV mask without a pellicle, photomask makers can use existing 193nm mask inspection tools. WebNov 27, 2024 · If you are shining the light through the mask like 193nm immersion lithography, it only goes through the pellicle once. But if it’s reflective, EUV light goes through the pellicle twice. If you have 85% transmission for the pellicle, then it’s actually 85% square to get it back. So you have a huge loss from that.

Developing such an EUV pellicle is very challenging, since 13.5nm light is absorbed by most materials. In addition, stringent thermal, chemical, and mechanical requirements must be achieved. ear cuffs non pierced gold
