Using light with a wavelength of just 13.5 nanometers, EUV lithography allows manufacturers to print incredibly fine features on silicon wafers, essential for producing the next generation of microchips.
Addressing Traditional Manufacturing Challenges
Traditional photolithography, which uses light with wavelengths of 193 nanometers, is limited in its ability to create smaller and more complex chip designs.
As the industry strives to follow Moore’s Law—the doubling of transistors on a microchip approximately every two years—these older methods require multiple patterning steps, which increase complexity, cost, and the potential for defects.
How It Works
EUV lithography employs a high-powered laser that hits droplets of tin to create plasma, emitting EUV light at a wavelength of 13.5 nm.
This light is collected and directed onto a mask that contains the chip design.
The light then transfers the pattern from the mask onto a silicon wafer coated with a photosensitive material called photoresist.
This process can create extremely small features, down to single-digit nanometers, in a more straightforward and fewer steps than traditional methods.
Advantages and Industry Impact
The implementation of EUV lithography offers several key advantages:
