Overview

This PatSnap article outlines Canon’s Nanoimprint Lithography (NIL) roadmap from 2015 to 2026, detailing its core Jet and Flash Imprint Lithography (J-FIL) technology. J-FIL eliminates wavelength constraints, enabling sub-10nm feature resolution without optical proximity correction. The roadmap traces breakthroughs in overlay accuracy and defectivity, marking its first commercial shipment in October 2024, with ambitions to achieve 10nm NIL and ultimately 2nm nodes, positioning NIL as a cost-effective alternative for advanced semiconductor manufacturing.

Background: Miniaturization Limits and the Quest for New Lithography Technologies

The semiconductor industry has relentlessly pursued chip miniaturization in accordance with Moore’s Law. However, conventional photolithography technologies are facing resolution limits imposed by the wavelength of light used. While Extreme Ultraviolet (EUV) lithography has been introduced to overcome these, EUV tools are exceedingly expensive, and their operational costs are high. Consequently, there is a strong demand for new lithography technologies that offer better cost-efficiency and fewer physical limitations. Nanoimprint Lithography (NIL) has emerged as one of the promising candidates.

Key Findings / Results: Canon’s NIL Roadmap and J-FIL Technology

This article reported by PatSnap details Canon’s strategic roadmap for Nanoimprint Lithography (NIL) from 2015 to 2026. Canon has focused its development efforts on its core technology, “J-FIL (Jet and Flash Imprint Lithography),” emphasizing its potential to revolutionize semiconductor manufacturing.

Key features of the J-FIL technology and the NIL roadmap include:

• Elimination of Wavelength Constraints: J-FIL operates by directly pressing a master mold onto a resist-coated substrate and then curing the resist with ultraviolet (UV) light to transfer the pattern. This process does not rely on the diffraction limits of light, thus bypassing the complex optical systems required by EUV. In principle, J-FIL can form extremely fine patterns, enabling sub-10nm feature resolution without the need for complex Optical Proximity Correction (OPC).
• Improved Overlay Accuracy: The roadmap demonstrates technological breakthroughs in improving overlay accuracy—the precision with which new patterns are aligned with existing patterns on the wafer—to meet the stringent requirements of next-generation semiconductor devices. This is crucial for fabricating complex chips with multiple wiring layers.
• Defect Reduction Technologies: One of the primary challenges of NIL has been defect management (e.g., particle adhesion, air bubbles, incomplete transfers). The roadmap includes significant R&D in minimizing these defects. Canon is addressing these issues through innovations such as drop-on-demand resist dispensing and advanced mold cleaning technologies.
• Commercial Shipment and Future Nodes: The first commercial shipment of NIL equipment in October 2024 marked a pivotal milestone, transitioning NIL technology from the research phase to practical implementation. The roadmap aims to further evolve this technology to support state-of-the-art semiconductor processes, including 5nm, and ultimately targeting 2nm nodes, positioning NIL as a direct competitor for advanced patterning.

Technical Significance & Outlook: Enabling Cost-Effective, High-Performance Semiconductor Manufacturing

Canon’s Nanoimprint Lithography roadmap holds the potential to significantly alter the landscape of semiconductor manufacturing. If J-FIL technology can reliably achieve 2nm nodes, it will offer an alternative means to produce cutting-edge chips at substantially lower equipment and operational costs compared to EUV lithography. This could contribute to cost reduction and supply stabilization for semiconductor chips across a wide range of high-performance applications, including data centers, AI chips, and mobile devices.

NIL is expected to be particularly competitive in manufacturing devices with highly repetitive patterns, such as NAND flash memory, as well as specialized devices like micro-LEDs, advanced optical components, and MEMS sensors. The advancement of this technology not only reinforces Japan’s technological presence in the semiconductor industry but also contributes to the diversification and resilience of the global semiconductor supply chain. Canon’s continuous innovation serves as a prime example of the benefits nanotechnology brings to advanced manufacturing.
