The Equipment, Materials and Process-Control Markets Behind Sub-3nm Logic, HBM and Chiplet Integration

Mobility Foresights Technology Research | Hub Analysis | September 2026

Leading-edge chipmaking is going through its biggest set of simultaneous changes in over a decade:

• New transistor structure. Gate-all-around transistors replaced FinFETs at the 2 nm class, with volume production beginning in 2025.
• Backside power. Power delivery is moving to the back of the wafer.
• High-NA EUV. High-numerical-aperture EUV lithography, first shipped at the end of 2023, is entering production.
• Advanced packaging. Packaging has become as important as the front end, because AI accelerators depend on stacking HBM and chiplets side by side on large interposers.

Governments are funding fab construction through the U.S. CHIPS Act, the EU Chips Act and programs in Japan, Korea and India. Meanwhile, geopolitics, PFAS regulation and helium supply have exposed the fragility of the materials that fabs depend on.

This hub brings together 67 Mobility Foresights market studies across six areas: EUV lithography and photoresists; etch, deposition and front-end equipment; advanced packaging and bonding; metrology, inspection and process monitoring; substrates and semiconductor materials; and fab chemicals, gases and supply-chain risk.

Key Takeaways

• High-NA EUV is reshaping the lithography materials stack. New resists, pellicles, optics and yield-management tools are needed.
• Etch and deposition intensity keeps rising. Gate-all-around transistors, 3D NAND and backside power add process steps, with atomic-level control.
• Advanced packaging is the new bottleneck. Thermo-compression and hybrid bonding, interposers and HBM packaging materials are growing faster than wafer equipment overall.
• Process control is moving in-situ. Sensors inside chambers and AI-driven predictive maintenance are becoming standard to protect yield at advanced nodes.
• Materials supply is a strategic risk. Specialty gases, helium, fluoropolymers and SiC substrates face geopolitical, regulatory and financial pressure.

How We Segment Semiconductor Manufacturing

1. EUV Lithography and Photoresists

Extreme ultraviolet (EUV) lithography prints the finest features on leading-edge chips. High-NA EUV, with a larger numerical aperture for sharper images, is being introduced for nodes beyond 2 nm. Our High-NA EUV production market report covers tool deployment and node adoption, and the extreme ultraviolet optical components market study covers the mirrors and optics that make it possible. Protecting the photomask is its own market: the EUV pellicle materials market report covers the ultra-thin membranes that must survive intense EUV exposure.

2. Etch, Deposition and Front-End Equipment

Geopolitics is the other risk. A large share of the world's helium, which fabs use for cooling and purging, comes from a small number of producing regions including Qatar. The US–Iran war impact on helium supply shortage market and US–Iran war impact on semiconductor manufacturing cost inflation market reports model how Middle East conflict could affect helium availability and fab operating costs. The semiconductor manufacturing localization market study covers government-funded fab construction and the relocation of supply chains that follows.

Frequently Asked Questions

What is High-NA EUV lithography?

High-NA EUV uses optics with a larger numerical aperture than standard EUV, allowing finer features to be printed in a single exposure. It is being introduced for logic nodes beyond 2 nm.

What is backside power delivery?

Backside power delivery moves the power-carrying wires to the back of the wafer, freeing space on the front for signal wiring and improving performance and power efficiency.

Why is advanced packaging a bottleneck for AI chips?

AI accelerators combine processor chiplets and HBM stacks on large interposers, which requires specialized bonding and packaging capacity that has not expanded as fast as demand.

What is hybrid bonding?

Hybrid bonding joins chips or wafers through direct copper-to-copper and dielectric bonds without solder bumps, enabling much finer connection pitches for stacked memory and chiplets.

Why are in-situ sensors important in semiconductor fabs?

They measure plasma, deposition and etch conditions inside the process chamber in real time, allowing immediate control and early detection of problems that would otherwise reduce yield.

How could PFAS regulation affect chipmaking?

Fluoropolymers and some fluorinated chemicals are widely used in fab equipment and processes. Broad PFAS restrictions could require substitutes such as PVDF or other materials, or specific exemptions for semiconductor uses.
