Enabling the next step in efficiency

Semiconductors are all around us in every single electronic device we use. That is how they make an impact in our everyday. Progress in the semiconductor industry continues fast driven by Moore’s Law aimed at doubling the transistor density on a wafer every two years. Higher transistor density will lead to more efficient processors and memory chips for the benefit of everyone using electronic devices.

To keep up with the pace of development, the industry has developed extreme ultraviolet lithography (EUV) technology. Using extreme ultraviolet wavelengths, this wafer exposure technology improves resolution and allows producing wafers with transistor node sizes of 7 nm or less. EUV lithography technology provides an optimal choice for next generation applications such as 5G, AI and the automotive industry.

Canatu CNT plays a role in enabling breakthroughs in the rapidly changing semiconductor industry.

EUV pellicles

Overcoming challenges in EUVL continues. EUV pellicles are membranes that protect the photomask from particle contamination while permitting high EUV transmission. EUV pellicles made of Canatu CNT are a critical enabler of high yield and throughput in high-volume semiconductor manufacturing, granting them unique benefits unparalleled by other materials.

Taking semiconductors to a smaller scale

As volumes rise in semiconductor manufacturing and ever-smaller features are printed on them, there is greater pressure to avoid defects. Tiny defects lead to errors on the wafer, causing costly yield losses.

Canatu has a unique solution based on CNT membrane to enable nanoscale debris filtering in a demanding environment: high EUV transmittance, low reflection and flare, high heat resistance and mechanical strength.

EUV pellicles are membranes that protect the photomask from particle contamination while permitting EUV transmission. The CNT membrane must be thin enough to limit the imaging impact while robust enough to survive handling.
