Semiconductor
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.
Canatu CNT plays a key role in advancing the EUV process required for producing the most advanced microchips. Today, Canatu is a prominent supplier of CNT -based products and manufacturing equipment for the semiconductor industry. Our product portfolio includes EUV pellicles, debris filters, and optical filters for EUV and X-ray filter applications.
Our products
The world’s thinnest and strongest carbon nanotube membranes, tailorable for your exact needs. Applicable for high-power EUV lithography and X-Ray filter applications. Made of the most advanced carbon nanotubes, known for their exceptional purity and properties.
EUV pellicles are membranes used to protect the photomask from contamination while permitting high EUV transmission. EUV pellicles made of Canatu CNT offer high transmittance and 15% higher performance compared to conventional EUV pellicles.
Canatu CNT membranes are well suited for use in X-Ray filter applications because of their high X-Ray transmittance, resistance to pressure differentials, and chemical inertness. These X-Ray filters can be placed e.g. in front of an X-Ray detector to block particles, electrons, and photons that fall outside the desired energy range, while providing high X-Ray transmittance and enduring high temperatures & differential pressure conditions.
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.
