Comparative Analysis: Quantum vs. Traditional Lithography Methods

Wavelength-selective quantum lithography represents a significant paradigm shift in the pursuit of ultra-high-resolution patterning, particularly as traditional photolithography approaches its physical limits. In 2025, the comparative landscape between quantum and conventional lithography methods is defined by both technological milestones and the evolving demands of semiconductor fabrication.

Traditional optical lithography, dominated by deep ultraviolet (DUV) and extreme ultraviolet (EUV) sources, has seen continuous improvements in resolution through shorter wavelengths and advanced techniques like multiple patterning. EUV lithography, using 13.5 nm wavelength light, is now well established in high-volume manufacturing at leading-edge foundries, enabling features below 5 nm in logic devices (ASML). However, further scaling is hindered by the diffraction limit and challenges in optics, materials, and mask technology.

Wavelength-selective quantum lithography exploits quantum entanglement and multi-photon interference to surpass the Rayleigh diffraction limit, achieving pattern resolutions theoretically down to λ/2N, where N is the number of entangled photons involved. This approach leverages quantum states of light, such as N00N states, to create interference fringes with spacings much smaller than the illuminating wavelength. Experimental systems have demonstrated sub-diffraction patterning using entangled photons at visible and UV wavelengths, promising much finer features than achievable with classical methods (Nikon Corporation).

A comparative analysis in 2025 highlights several key differences:

  • Resolution: Quantum lithography theoretically achieves higher resolution for a given wavelength, limited by photon loss and source brightness. EUV lithography’s practical resolution is limited by optics and resist performance.
  • Complexity: Quantum lithography requires entangled photon sources and phase-stable optical setups, posing significant engineering challenges. In contrast, traditional systems are mature, with extensive industrial infrastructure.
  • Throughput: Current quantum lithography systems operate at slow exposure rates due to low photon flux; traditional lithography delivers high throughput suitable for mass production (Canon Inc.).
  • Material Compatibility: Conventional photoresists are optimized for DUV/EUV; quantum imaging may necessitate development of new quantum-sensitive materials.

Looking ahead, industry stakeholders are exploring hybrid approaches, integrating quantum techniques with existing lithographic processes to enhance resolution without sacrificing throughput. Research collaborations between quantum optics groups and lithography equipment makers are expected to intensify, focusing on scalable quantum light sources and quantum-compatible resists. While commercial deployment on production lines remains a medium-term prospect, proof-of-concept demonstrations in research and pilot facilities are anticipated in the next few years (IBM).
