WebOct 7, 2024 · It is mounted a few millimeters above the surface of the photomask so that if particles land on the pellicle, they will be too far out of focus to print. 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. WebWe manufacture the highest-quality laser patterned photomasks at the best value. A photomask is an image-transferring tool. The photomask is comprised of a solid, transparent substrate, such as glass or fused silica, which has an opaque coating on one surface into which a microscopic pattern has been etched, leaving some regions …

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.
