Manufacturing Challenges: Technical Barriers and Solutions
Nonplanar photolithography equipment manufacturing faces unique technical barriers, particularly as semiconductor and microfabrication industries demand solutions for patterning on curved, flexible, or irregular surfaces. As of 2025, the primary challenges involve precise alignment and focus control, mask deformation, and ensuring uniform exposure across non-flat substrates. Addressing these issues is critical for applications ranging from flexible displays to biomedical devices.
A significant technical barrier remains the development of advanced optical systems capable of dynamic focus adjustment and distortion correction. Conventional photolithography tools, designed for flat wafers, struggle to maintain image fidelity over three-dimensional surfaces. Companies such as Nikon Corporation and Canon Inc. are actively investing in adaptive optics and variable projection systems to overcome these hurdles. For example, adaptive lens elements and real-time feedback mechanisms are being integrated to correct for curvature-induced aberrations during exposure.
Another persistent challenge is the fabrication and handling of conformable masks or reticles. Nonplanar substrates can require flexible or stretchable photomasks that maintain pattern accuracy despite bending or stretching. As of 2025, suppliers like MicroChemicals GmbH are developing novel materials and processes for flexible photomask production, including polymer-based masks and direct-write techniques to bypass traditional mask requirements.
Uniform photoresist coating on non-flat surfaces is another manufacturing bottleneck. Traditional spin coating struggles with inconsistent thickness on nonplanar substrates. In response, equipment manufacturers such as SÜSS MicroTec SE have introduced spray coating and meniscus coating systems that deliver more uniform resist layers over complex geometries. These advances are supported by closed-loop process controls and in-situ metrology.
The outlook for the next few years includes accelerated collaboration between equipment vendors and end-users in fields like flexible electronics and medical sensors. Industry initiatives, such as those led by SEMI, are driving standardization efforts for nonplanar lithography processes. It is anticipated that by the late 2020s, hybrid lithographic platforms—combining projection, direct-write, and maskless strategies—will become increasingly viable for commercial production.
Despite these advancements, cost, yield, and throughput remain concerns. The integration of machine learning for process optimization and adaptive control is expected to further mitigate technical barriers, positioning nonplanar photolithography equipment as a critical enabler for next-generation microfabrication.
Supply Chain and Partnerships: Collaborations Across the Value Chain
The landscape of nonplanar photolithography equipment manufacturing in 2025 is defined by a complex and evolving web of supply chain relationships and strategic partnerships.

Leading equipment providers such as ASML and Canon Inc. have intensified their cooperation with specialty optics suppliers and materials companies to address the unique challenges in processing non-flat surfaces. For example, ASML’s ongoing supply agreements with precision optics manufacturers are crucial for the development of next-generation projection systems capable of conformal patterning. Canon, which has long invested in maskless lithography and nanoimprint technologies, announced in late 2024 expanded partnerships with resist material suppliers to ensure reliable pattern transfer on complex topographies.
Upstream, suppliers of UV light sources, advanced photoresists, and nanoimprint materials—such as Tokyo Ohka Kogyo Co., Ltd. and Dow—are aligning their R&D with equipment manufacturers’ roadmaps. These collaborations aim to optimize material formulations for better adhesion, resolution, and defect control in nonplanar contexts. In early 2025, several suppliers reported joint pilot lines with toolmakers, accelerating feedback cycles and reducing time-to-market for new processes.
At the system integration level, partnerships between equipment vendors and semiconductor foundries, such as TSMC and Samsung Electronics, have deepened. Foundries are increasingly co-developing process flows and tool specifications with lithography equipment manufacturers to enable faster qualification of nonplanar processes for high-volume manufacturing. For instance, in Q1 2025, TSMC confirmed expanded technical exchanges with multiple equipment suppliers to address overlay accuracy and defectivity in 3D device fabrication.
Looking ahead, the next few years are expected to bring further integration of supply chain partners through joint development agreements, shared pilot facilities, and cross-licensing of technology. International consortia and industry groups—such as SEMI—are facilitating pre-competitive collaboration to standardize metrology and process control for nonplanar lithography. Such initiatives are critical for mitigating supply chain risks and ensuring interoperability as nonplanar device architectures become mainstream.
Overall, the competitive and technical challenges of nonplanar photolithography are forging closer, more agile partnerships across the value chain, with 2025 marking a period of intensified collaboration and ecosystem maturity.
Regulatory and Standardization Updates: Compliance Trends
The regulatory landscape for nonplanar photolithography equipment manufacturing is evolving rapidly, driven by the increasing complexity of advanced packaging and heterogeneous integration. As of 2025, regulatory bodies and industry consortia are refining standards to address new challenges in three-dimensional (3D) and curved-surface device fabrication. The International Electrotechnical Commission (IEC) and the Semiconductor Equipment and Materials International (SEMI) continue to play pivotal roles in standardization, updating technical standards to include criteria for alignment, cleanliness, and defect inspection unique to nonplanar surfaces.
SEMI has advanced several standards applicable to nonplanar photolithography, such as SEMI S2 for equipment safety and SEMI E10 on equipment reliability. These standards are being reviewed to ensure they address emerging concerns, including particle contamination and process uniformity on non-flat substrates. The SEMI Advanced Packaging Committee is also examining new guidelines for mask alignment and overlay accuracy for 3D surfaces, with draft revisions expected by late 2025 (SEMI).
On the international front, the IEC Technical Committee 47 (TC 47), focused on semiconductor devices, has initiated working groups to establish test and measurement protocols specific to nonplanar lithography systems. The aim is to harmonize inspection and validation procedures across regions, which is particularly important as supply chains become more globalized (International Electrotechnical Commission).
Environmental and safety compliance remains a top priority. With new photolithography chemistries and exposure sources being introduced for nonplanar processing, manufacturers must comply with evolving regulations on hazardous material handling and emissions. For example, equipment manufacturers such as ASML and Canon Inc. are adapting their processes and documentation to ensure compliance with the European Union’s RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) directives as applied to advanced semiconductor equipment.
Looking ahead, regulatory focus is expected to intensify around data integrity (e.g., traceability of process conditions on complex substrates) and cybersecurity, as nonplanar photolithography equipment becomes increasingly networked and integrated with factory automation systems. The SEMI Cybersecurity Initiative is developing best practices that will likely become de facto requirements for equipment suppliers entering the mid-to-late 2020s (SEMI).
As the sector grows, ongoing engagement with standards bodies and proactive compliance strategies will be crucial for equipment manufacturers to ensure market access and operational resilience in the face of tightening global regulations.
