Introduction: The Quantum Leap in Photolithography

Quantum photolithography is emerging as a transformative technology in semiconductor manufacturing, offering the potential to overcome the physical and economic limitations of classical photolithography techniques. As the semiconductor industry seeks ever-smaller process nodes—with targets now below 2 nm—quantum-enabled processes are gaining significant attention for their ability to control features at atomic and sub-nanometer scales. The central premise of quantum photolithography is to exploit quantum phenomena, such as entanglement and multi-photon interference, to surpass the classical diffraction limit that constrains traditional optical lithography.

In 2025, research and initial pilot programs in quantum photolithography are progressing rapidly, with major industry players and specialized startups investing in diverse approaches. IBM and Intel are among the leaders in exploring quantum-enhanced lithographic masks and quantum light sources, aiming to improve resolution and reduce line edge roughness. These companies have published evidence that quantum correlations can enable feature patterning with spatial resolutions finer than the wavelength of the illuminating light, a feat unattainable by classical means. Meanwhile, ASML, the dominant supplier of extreme ultraviolet (EUV) lithography systems worldwide, has begun investigating hybrid quantum-classical solutions to synergize with their advanced EUV platforms, collaborating actively with research consortia and university spin-offs.

Technical milestones in 2024–2025 include demonstrations of quantum lithography using entangled photon pairs and NOON states to achieve patterning resolutions below 10 nm in laboratory settings. Several public–private partnerships, such as those involving IBM, Intel, and leading academic institutions, are developing scalable photon sources and integration protocols for quantum lithography modules in next-generation fabs.

Challenges: Technical Barriers and Scalability

Quantum photolithography represents a promising frontier for semiconductor manufacturing, leveraging quantum entanglement and multi-photon interference to potentially surpass the resolution limits of classical optical lithography. However, in 2025, significant technical barriers persist, particularly concerning scalability, process integration, and equipment readiness.

One of the primary challenges lies in the reliable generation and manipulation of entangled photon sources at throughput rates suitable for high-volume manufacturing. Current quantum light sources, such as those developed by companies like TOPTICA Photonics and Hamamatsu Photonics, can produce entangled photon pairs, but their brightness, stability, and integration with existing lithography steppers are not yet compatible with the speed and uniformity required for wafer-scale processing. Progress in single-photon and entangled-photon generation technologies is ongoing, but the photon flux remains orders of magnitude below what is needed for commercial fabrication.

Another major technical hurdle is the development of high-efficiency, large-area quantum masks and interference setups. Traditional mask manufacturing giants such as Photronics and HOYA Corporation are investigating quantum-compatible mask substrates and coatings, yet the precise control of quantum interference patterns over 300 mm wafers remains unproven at scale. Achieving uniform, repeatable quantum interference across large substrates is complicated by environmental noise, vibration, and the highly sensitive nature of quantum states.

Integration into the semiconductor manufacturing ecosystem also poses significant challenges. Current photolithography tools manufactured by industry leaders like ASML and Canon are not designed to handle quantum light sources or quantum masks. Retrofitting or developing entirely new quantum-compatible exposure systems would entail substantial capital investment and require close collaboration with quantum optics specialists, something the industry is only beginning to explore.

Finally, process scalability is inhibited by the lack of robust, high-throughput quantum metrology and process control tools. Established metrology providers such as KLA Corporation are in early stages of evaluating quantum-enhanced tools, but commercial offerings are not expected before the late 2020s. Without these, controlling critical dimensions at quantum lithography’s sub-wavelength resolutions remains a formidable challenge.

Looking forward, while proof-of-concept achievements in academic and national labs have demonstrated the theoretical viability of quantum photolithography, practical deployment at industrial scales will require breakthroughs in photon source technology, mask fabrication, quantum-compatible stepper design, and process metrology. Overcoming these barriers in the next few years will demand cross-disciplinary innovation and strong partnerships between quantum technology developers and leading semiconductor equipment manufacturers.

Applications: Quantum Photolithography in Advanced Semiconductors

This technique leverages the principles of quantum optics, such as entangled photon sources and quantum interference, to enhance resolution and control in the lithographic process. In 2025, industry leaders and research consortia are accelerating efforts to realize practical quantum photolithography systems, aiming to address the scaling challenges faced by traditional extreme ultraviolet (EUV) and deep ultraviolet (DUV) lithography.

A key area of progress is the development of entangled photon sources capable of generating high-brightness, stable photon pairs for quantum interference lithography. Companies such as Intel Corporation and Taiwan Semiconductor Manufacturing Company (TSMC) are actively exploring quantum-enhanced lithographic processes as part of their research into future nodes beyond 2 nm. These approaches seek to exploit multiphoton absorption processes, which, in theory, can achieve patterning resolutions surpassing the classical Rayleigh diffraction limit by a factor of the number of entangled photons used. In practice, this could enable critical dimension (CD) control at the sub-nanometer scale—a critical need for next-generation logic and memory devices.

The integration of quantum photolithography techniques is also being supported by major equipment manufacturers. ASML Holding, the world’s leading supplier of photolithography systems, is investing in quantum optics research with the goal of augmenting or eventually succeeding current EUV platforms.

Additionally, Nikon Corporation and Canon Inc. are conducting early-stage experiments to adapt their lithography hardware for quantum-enabled imaging, with a focus on improving overlay accuracy and defect reduction for advanced nodes.

Looking ahead to the next few years, quantum photolithography remains primarily in the experimental and pilot stages, as significant challenges in photon source scalability, resist sensitivity, and system integration must be overcome. However, the outlook is promising: the International Roadmap for Devices and Systems (IRDS) includes quantum-enhanced lithography as a strategic focus area for sub-1 nm device manufacturing. If current research trajectories continue, initial pilot lines incorporating quantum photolithography modules could begin appearing in advanced foundries by the late 2020s, potentially unlocking new pathways for Moore’s Law and enabling novel quantum-classical hybrid device architectures.
