In 2026, the semiconductor materials landscape is being reshaped by the push toward advanced nodes, 3D architectures, and regional localization of supply chains. Within this broad shift, three sub segments stand out as critical and fast‑moving: ALD/CVD precursors, photoresists and related lithography materials, and sputtering targets for interconnects and specialty films. Comparing their growth trajectories offers insight into where capital, innovation, and strategic focus are converging across the materials ecosystem.
This blog post uses structural industry logic—rather than precise numeric forecasts—to rank the relative growth momentum of these sub segments in 2026 and explain why precursors, photoresists, and targets are experiencing different levels of demand pressure, technology change, and pricing power.
Setting the stage: structural drivers in 2026
Semiconductor demand in 2026 is heavily influenced by AI accelerators, advanced logic for data centers and mobile, high‑density memory, power devices for EVs and renewables, and connectivity infrastructure. Across these applications, the number of process steps per wafer is rising, and the share of advanced nodes in leading‑edge fabs continues to increase.
Materials that scale directly with these trends—either because they are essential to advanced deposition, critical patterning, or complex interconnect stacks—see structurally stronger growth. At the same time, regional capacity expansions and localization efforts amplify demand for certain materials as new fabs ramp in multiple geographies.
Against this backdrop, ALD/CVD precursors, photoresists, and sputtering targets occupy distinct positions in the process flow and respond differently to the year’s technology and capacity drivers.
ALD/CVD precursors: top‑ranked growth engine
In 2026, ALD/CVD precursors sit at the top of the growth ranking among the three sub segments. Their demand is tightly coupled to the proliferation of complex 3D structures (gate‑all‑around transistors, 3D NAND, advanced DRAM capacitors) and to the broader shift toward more chemically sophisticated films and interfaces in logic and memory.
Every new layer deposited by ALD or advanced CVD requires tailored molecules—metal‑organic or inorganic precursors—whose usage scales with both wafer volume and process complexity. As devices adopt more stacks and tighter control over film properties, precursor consumption rises not only in quantity but also in diversity of formulations.
This combination—more wafers at advanced nodes, more deposition steps, and more specialized chemistries—creates a structural growth engine for precursors that is difficult to match.
Drivers of precursor growth in 2026
Several specific trends amplify precursor growth this year. First, wider deployment of high‑k/metal gate stacks and advanced liners/barriers in logic increases the number of ALD‑centric modules per wafer. Second, 3D NAND manufacturers continue to push layer counts higher, requiring repeated oxide and nitride deposition cycles with strict conformality in deep trenches.
Third, selective and area‑specific deposition techniques gain traction, demanding even more carefully engineered precursors that can differentiate between surfaces and avoid unwanted nucleation. This pushes precursor portfolios toward higher value‑added products with refined molecular design and purity control.
Finally, regional fab expansions—especially those aligned with leading‑edge technologies—bring new customers into the precursor market, reinforcing volume growth across multiple continents.
Photoresists: strong but more mature growth
Photoresists and lithography materials remain a core growth segment, but their trajectory in 2026 is somewhat more moderated compared with precursors. Resists are indispensable for patterning at all nodes, and EUV resists in particular see rising demand as more advanced logic and memory lines adopt EUV lithography for critical layers.
However, the resist segment already has a relatively high baseline volume and value, and much of its growth comes from technology upgrades (e.g., new EUV formulations, multi‑patterning support) rather than pure volume explosions. Mature nodes continue to consume large quantities of DUV resists, while leading‑edge nodes shift mix toward more complex chemistries.
The result is robust, steady growth with strong innovation, but not the same degree of volumetric and portfolio expansion seen in precursors.
Key photoresist growth themes in 2026
Several themes shape photoresist growth this year. EUV adoption expands to more layers and more products, increasing demand for advanced resists and related materials such as top coats and ancillary chemistries. This drives higher value per wafer at the leading edge.
At the same time, advanced DUV patterning remains relevant for non‑critical layers and for nodes just below the leading edge, keeping demand for ArF and KrF resists healthy. Multi‑patterning and resolution enhancement techniques also create opportunities for specialized resists tuned to complex optical environments.
However, the number of lithography steps per wafer does not grow as explosively as deposition steps in some architectures, placing photoresists slightly behind precursors in the growth ranking, despite their central importance.
Sputtering targets: solid, selective growth
Sputtering targets—materials used in PVD processes to deposit metals and certain dielectrics—experience solid but more selective growth in 2026. They serve interconnect stacks, barrier and seed layers, magnetic films, and some specialty applications. As devices adopt more metal layers and complex stacks, targets see incremental volume increases.
However, growth is constrained by several factors. Some interconnect innovations shift material usage rather than simply increasing total metal volume. Certain processes migrate from PVD to ALD or CVD approaches, especially for ultra‑thin liners and barriers, which can cap target demand in specific modules.
Overall, targets benefit from the trend toward more layers and advanced packaging interconnects, but their growth rates tend to lag behind the more chemically leveraged precursor segment and the high‑value portions of the resist market.
Ranking overview: Precursors > Photoresist > Targets
Putting these dynamics together, a qualitative growth ranking for 2026 among the three sub segments is: precursors at the top, photoresists in second place, and sputtering targets third. Precursors enjoy the most direct leverage to advanced architectures and layer count increases, making their growth structurally stronger.
Photoresists hold a powerful position driven by EUV adoption and ongoing patterning needs across nodes, but their growth is tempered by more mature volume bases and somewhat slower expansion in lithography steps relative to deposition steps. Targets, while essential, see more gradual growth as certain roles are redistributed among deposition technologies and as interconnect design changes focus more on replacing materials than adding unlimited layers.
This ranking reflects how each sub segment is positioned within the 2026 process stack rather than asserting precise numerical differences.
Pricing power and margin dynamics
Growth ranking is not only about volume; it also ties into pricing power and margins. Precursor suppliers often operate in highly specialized niches with strong co‑development relationships to fabs. This enables differentiated products and, in many cases, firmer pricing, especially for precursors that are difficult to substitute.
Photoresist vendors also enjoy strong pricing power at the leading edge, particularly for EUV resists, where few qualified suppliers and intense performance requirements allow premium pricing. At mature nodes, competitive pressure and commoditization are higher, moderating margins.
Target manufacturers face more intense competition in some metals and applications, with pricing influenced by commodity metal markets and by customers’ willingness to switch suppliers once qualification hurdles are cleared. Their margin profiles can be robust in niche materials but more constrained in mainstream interconnect metals.
Technology intensity and R&D leverage
Precursor and photoresist segments both exhibit high technology intensity, meaning R&D investments translate directly into product differentiation and growth opportunities. Designing new molecules, refining purity, and tuning reactivity are central to precursor innovation; developing new resist chemistries, controlling line edge roughness, and managing stochastic effects are central to lithography innovation.
Targets, while technologically demanding in terms of purity, microstructure, and mechanical stability, often face less dynamic shifts in fundamental chemistry. Many key metals—copper, tungsten, cobalt, and certain alloys—remain standard, with innovation focused on process integration rather than wholesale material replacement.
This difference in technology intensity helps explain why precursors and resists tend to attract more R&D capital and strategic partnerships, reinforcing their higher relative growth potential.
Impact of regional fab expansions
Regional fab expansions in 2026—spanning Asia, North America, and parts of Europe—affect all three segments, but not equally. New leading‑edge lines with strong ALD/CVD usage disproportionately lift precursor demand, while new EUV lithography capacity boosts high‑end resist consumption.
Targets benefit from any additional interconnect and metallization capacity, yet some new fabs may adopt more ALD/CVD‑heavy flows for certain layers, altering the balance of PVD versus other deposition techniques. In mature‑node expansions (for automotive, industrial, and IoT), resist and target demand both rise, though precursors gain mainly where advanced nodes or 3D architectures are present.
Overall, regional expansions reinforce the existing growth ranking by channeling more advanced‑node volume into precursor and resist‑intensive modules.
Localization and supply chain considerations
Localization initiatives influence growth patterns by encouraging domestic or regional production of key materials. Precursors, due to their strategic nature and tight coupling to advanced nodes, often feature prominently in localization strategies. Governments and fabs are keen to reduce dependence on imported molecules that are critical to advanced deposition.
Photoresists, especially EUV formulations, are also considered strategic, yet localization is complicated by intellectual property, specialized raw materials, and the small number of global leaders. Targets may be easier to localize in some cases, especially for standard metals, but high‑purity and specialty alloys still require sophisticated infrastructure.
Localization efforts can accelerate growth for domestic suppliers in all three segments, but the structural importance of precursors and photoresists means they typically attract more attention and potentially more investment support.
Customer collaboration and co‑development
In 2026, close co‑development between fabs and material suppliers is a distinguishing feature of growth segments. Precursor suppliers work intimately with process engineers to craft molecules that fit specific deposition windows, interface chemistries, and reliability targets. This collaboration deepens relationships and locks in future demand.
Photoresist developers collaborate with lithography tool vendors and fabs to manage stochastic defects, CD control, and resist stability under EUV exposure. Joint work on process recipes, post‑exposure treatments, and metrology cements their role in the ecosystem.
Target suppliers also engage in co‑development around film stress, adhesion, and electromigration, though the pace of fundamental change is often slower. As a result, co‑development disproportionately amplifies growth in precursors and resists, where new device architectures constantly open space for novel chemistries.
Risk and volatility across segments
High growth segments often carry higher risk and volatility. Precursor markets can be sensitive to rapid technology transitions, as new architectures may suddenly demand different molecules or shift volume between material families. Suppliers must manage the risk of obsolescence for older products while investing aggressively in new ones.
Photoresist vendors face risks tied to lithography technology adoption: delays or changes in EUV deployment plans can alter demand trajectories. They also must navigate strong performance expectations, where small chemistry issues can have large yield implications.
Targets, while somewhat more stable in product chemistry, can face volatility linked to metal prices, regional supply constraints, or sudden shifts in interconnect design preferences. Their risk profile is often more tied to external commodity dynamics than to rapid technology obsolescence.
This mix of risk factors shapes how companies in each segment approach investment and portfolio management, feeding back into growth strategies.
Implications for suppliers and investors
For suppliers, the 2026 growth ranking suggests that companies with strong positions in ALD/CVD precursors and advanced resists are particularly well‑placed to capture upside from leading‑edge nodes and 3D architectures. They must, however, sustain high R&D intensity and deep customer engagement to stay ahead.
Target manufacturers may find best opportunities in specialized metals, advanced packaging, and interconnect innovations, where differentiation still matters. More commoditized segments demand efficiency and reliability rather than aggressive technological leaps.
Investors looking at materials portfolios might weigh higher‑growth, higher‑risk precursor and resist businesses against steadier but slower‑growing target operations, crafting balanced exposure across these segments based on risk tolerance and technology convictions.
Conclusion: growth shaped by position in the stack
In 2026, the semi material sub segment growth ranking of precursors versus photoresists versus targets reflects where each sits in the evolving process stack. ALD/CVD precursors lead the growth chart, powered by expanding 3D structures and advanced nodes. Photoresists follow closely, buoyed by EUV adoption and enduring patterning needs, while sputtering targets deliver solid but comparatively slower growth tied to interconnect and packaging evolution.
For the industry, understanding this ranking is less about chasing exact percentages and more about recognizing which material families are most leveraged to key technological and capacity trends. That recognition can guide strategic planning, R&D investments, and partnership choices as the semiconductor materials ecosystem continues to expand and diversify.
