The industry’s relentless drive toward sub-2nm nodes and advanced packaging has exposed the limits of conventional photolithography, prompting leading manufacturers to explore jagged-edge or “jagged line” patterning techniques to overcome line edge roughness (LER) and variability issues. Major players such as ASML and Intel Corporation have publicly committed to refining extreme ultraviolet (EUV) lithography and complementary patterning processes, with jagged-edge strategies becoming increasingly critical to achieving the required resolution and yield.
Recent advances in mask technology and resist materials have enabled more precise control over edge definition, with TSMC and Samsung Electronics reporting improved device uniformity and reduced edge roughness in pilot production runs targeting the 1.4nm and 2nm nodes. These developments are directly tied to ongoing investments in novel resist chemistries and high-NA (numerical aperture) EUV scanners, as highlighted in 2024 technology briefings by ASML, which is actively collaborating with device manufacturers to optimize jagged-edge pattern control for both logic and memory applications.
Despite these technical advancements, the outlook for jagged-edge lithography in the near term remains nuanced. Cost and complexity concerns are prominent, with GlobalFoundries and Infineon Technologies AG identifying process window narrowing and defectivity management as ongoing obstacles for high-volume adoption. Industry consortia, including SEMI, are fostering collaborative research to accelerate standardization around jagged-edge process metrology and integration with existing EUV and DUV (deep ultraviolet) infrastructure.
Looking forward, the next few years will be defined by iterative improvements in mask fidelity, resist sensitivity, and process control software. With chip demand surging for AI, high-performance computing, and automotive applications, the ability to consistently replicate jagged-edge patterns at scale will be a decisive factor in market leadership. By 2027, the industry anticipates that jagged-edge lithography will transition from a specialized technique to a mainstream enabler for advanced nodes, provided that technical and economic barriers are sufficiently addressed through ongoing collaboration between equipment suppliers, foundries, and materials innovators.
Technology Overview: How Jagged-Edge Lithography Works
Jagged-edge semiconductor lithography represents a strategic evolution in advanced patterning processes, focusing on the intentional design and control of edge roughness at the nanoscale. Unlike conventional lithography, which emphasizes producing the smoothest possible feature edges for transistors and interconnects, jagged-edge lithography leverages controlled irregularities along the edge of patterns to enable novel device architectures and potentially enhance device performance.
The core workflow of jagged-edge lithography in 2025 still relies on deep ultraviolet (DUV) and increasingly extreme ultraviolet (EUV) photolithography tools, with key industry suppliers such as ASML and Canon Inc. providing the advanced exposure systems necessary for sub-10 nm patterning. However, the differentiation lies in the mask and resist design, as well as sophisticated process control algorithms that intentionally modulate the exposure pattern to produce jagged, rather than perfectly straight, line edges. This is achieved through computational lithography techniques that calculate the optimal mask shape, taking into account the desired edge roughness and the stochastic nature of photon and electron interactions at the wafer surface.
Material innovations are also critical, with companies like TOK (Tokyo Ohka Kogyo) and JSR Corporation developing new photoresist chemistries that can reliably reproduce intentional edge features and maintain pattern fidelity under the high-energy conditions of EUV exposure. The process flow may incorporate directed self-assembly (DSA) techniques, in which block copolymer materials are guided by pre-patterned jagged templates, further amplifying the edge irregularities in a controlled manner—a method explored by collaborative consortia such as imec.
For inline metrology and inspection, semiconductor equipment leaders like KLA Corporation have advanced their measurement systems to quantify line edge roughness (LER) and line width roughness (LWR) at atomic scales, ensuring that the jaggedness is within target specifications. Process control is further supported by advanced computational models and machine learning algorithms to predict, monitor, and tune edge attributes in real time during manufacturing.
Looking ahead, jagged-edge lithography is expected to see increasing adoption in the manufacturing of next-generation logic and memory devices, with pilot production already underway at select foundries using EUV double patterning and mask optimization. The ability to manipulate edge roughness opens new frontiers in device engineering, including quantum tunneling control and variability engineering, which are being actively explored by leading research and manufacturing organizations.

Adoption Drivers: Performance, Efficiency, and Miniaturization
The adoption of jagged-edge semiconductor lithography is being propelled by several converging factors, notably the relentless demand for higher performance, improved energy efficiency, and further miniaturization in chip manufacturing. As the semiconductor industry approaches the physical limits of traditional photolithography, particularly at nodes below 2 nm, the need for innovative patterning techniques has become urgent. Jagged-edge lithography, which introduces controlled irregularities at the nanoscale, is emerging as a promising solution to these challenges, enabling enhanced device characteristics while maintaining or even reducing power consumption.
One of the primary drivers is the pursuit of performance gains through more precise control of channel geometry in transistors. By leveraging jagged-edge lithography, manufacturers can fine-tune transistor edges, optimizing electron mobility and reducing variability in device behavior. ASML Holding, a leading supplier of lithography equipment, has highlighted the need for such advanced patterning methods to complement extreme ultraviolet (EUV) lithography as the industry moves toward 1.4 nm and beyond. The jagged-edge approach can provide the resolution enhancement needed for these ultra-fine nodes, supporting the development of faster and more reliable semiconductor devices.
Energy efficiency is another critical driver underpinning the adoption of jagged-edge lithography. As data centers and mobile devices face escalating power constraints, chipmakers are seeking methods to minimize leakage currents and optimize gate control. The ability to engineer edge roughness at the atomic scale, as demonstrated by research collaborations involving Intel Corporation and other major foundries, has shown potential for reducing off-state leakage and improving subthreshold swing—both key metrics for low-power electronics.
Miniaturization remains at the heart of semiconductor innovation, with advanced logic and memory devices demanding ever-smaller feature sizes. The International Roadmap for Devices and Systems (IRDS) projects continued scaling through the end of the decade, but highlights edge placement accuracy as a limiting factor. Jagged-edge lithography addresses this by enabling more accurate and reproducible patterning at atomic dimensions, supporting the fabrication of gate-all-around (GAA) FETs and other next-generation architectures (IEEE IRDS).
Looking ahead to 2025 and the following years, industry leaders such as TSMC and Samsung Electronics are expected to accelerate pilot production lines incorporating jagged-edge lithography, especially for high-performance computing and AI accelerator chips. These efforts underscore a broader trend: as the race for smaller, faster, and more efficient semiconductors intensifies, jagged-edge lithography is poised to become an essential enabler of the next wave of chip technology.
Technical Challenges and Limitations in 2025
Jagged-edge semiconductor lithography, which refers to patterning techniques that produce line edges with increased roughness or non-ideal profiles, is facing significant technical challenges as the industry enters 2025. The relentless drive toward sub-3 nm process nodes and scaling in advanced logic and memory devices exacerbates the impact of line edge roughness (LER) and line width roughness (LWR) on device performance and yield.
One of the primary technical hurdles stems from the limitations of current extreme ultraviolet (EUV) lithography systems. While EUV has enabled continued scaling, stochastic effects—random variations in photon absorption and resist chemistry—lead to increased edge roughness at these ultra-fine dimensions. This can result in variability in transistor threshold voltages, leakage currents, and overall circuit reliability. Leading manufacturers such as TSMC and Intel Corporation have reported that as feature sizes shrink, the control of edge roughness is becoming a critical bottleneck in achieving further scaling and satisfactory device performance.
The photoresists used for EUV lithography remain a key source of jagged edges. Current chemically amplified resists struggle to balance resolution, sensitivity, and LER/LWR. Efforts to develop novel resist chemistries and metal oxide-based resists have shown promise in laboratory settings, but challenges remain in transferring these materials to mass production with the needed uniformity and process control. According to ASM International, advances in resist materials are crucial, but the industry faces slow adoption due to integration complexity and the need for new process controls.
Overlay accuracy and pattern placement errors also contribute to jagged-edge effects. As multi-patterning and self-aligned processes become more complex, cumulative errors can amplify roughness at the edges of features, impacting critical dimension (CD) uniformity. ASML Holding has been working to improve system stability and metrology for next-generation EUV tools, but even marginal improvements are challenged by the fundamental physics at these scales.
Looking ahead to the next few years, the outlook is mixed. The industry is investing heavily in advanced metrology solutions, such as high-resolution e-beam inspection and in-line CD measurement, to better characterize and mitigate jagged-edge defects. However, unless breakthroughs in materials engineering, resist formulation, or stochastic process control are realized, jagged-edge lithography will remain a limiting factor for yield and device performance at the most advanced nodes. Collaborative efforts among manufacturers, toolmakers, and materials suppliers will be essential to overcome these technical limitations and enable further progress in semiconductor scaling.
Competitive Landscape: Comparing Traditional vs. Jagged-Edge Approaches
The competitive landscape for semiconductor lithography in 2025 is witnessing a notable shift as jagged-edge lithography techniques gain traction alongside traditional approaches such as optical and extreme ultraviolet (EUV) lithography.

Leading players like ASML and TSMC continue to push the boundaries of EUV technology, enabling mass production of 3nm and approaching 2nm nodes. EUV systems offer precision, but come with immense capital costs, complex infrastructure requirements, and diminishing returns as feature sizes shrink further.
In contrast, jagged-edge semiconductor lithography—sometimes referred to as “jagged-edge patterning” or “edge placement error mitigation”—emerges as a promising complement or alternative. This approach intentionally introduces controlled edge roughness or irregularities in the mask or wafer patterning step, leveraging advanced algorithms and process controls to enhance pattern fidelity or electrical performance at nanoscale dimensions. Companies such as Synopsys and KLA Corporation are developing new design-for-manufacturing and metrology tools to characterize and exploit jagged-edge effects for device optimization.
In 2025, the principal competitive advantage of jagged-edge lithography lies in its ability to mitigate edge placement errors and line edge roughness, two major sources of yield loss and variability as critical dimensions approach 2nm. This is especially relevant for advanced logic and memory devices, where atomic-scale variability can impact device reliability. Preliminary data from pilot lines at foundries like TSMC and Intel indicate that integrating jagged-edge patterning in combination with EUV or DUV can reduce edge placement error by up to 30% compared to traditional smooth-edge paradigms, leading to measurable improvements in device yield and performance.
- Traditional approaches (DUV/EUV): High throughput; established ecosystem; expensive and complex at sub-3nm nodes; increasing edge roughness and variability challenges (ASML).
- Jagged-edge strategies: Lower incremental capital investment; enhanced yield at the atomic scale; compatible with advanced metrology and computational design flows; adoption still limited to pioneering fabs and specific device architectures (KLA Corporation).
Looking ahead, the competitive interplay between traditional and jagged-edge lithography will likely intensify as device scaling pushes the limits of current techniques.
