According to the latest TechSci Research report, “Atomic Layer Deposition Market – Global Industry Size, Share, Trends, Competition Forecast & Opportunities, 2020-2030F”, the Global Atomic Layer Deposition (ALD) Market was valued at USD 3.01 billion in 2024 and is projected to reach USD 4.78 billion by 2030, expanding at a CAGR of 7.85% during the forecast period. This growth is being fueled by the increasing complexity of semiconductor architectures, the transition to sub-5nm and 3nm process nodes, and the rising adoption of ALD across emerging applications such as flexible electronics, displays, and energy storage solutions.

Plasma-Enhanced ALD Driving Advanced Node Manufacturing

As semiconductor fabrication moves toward smaller geometries, Plasma-Enhanced Atomic Layer Deposition (PEALD) has emerged as a critical enabler of next-generation devices. Traditional thermal ALD requires operating temperatures of around 200°C–300°C, which can be unsuitable for temperature-sensitive substrates. In contrast, PEALD leverages plasma to enhance precursor surface reactivity, enabling deposition at temperatures below 100°C. This makes PEALD particularly attractive for Back End of Line (BEOL) processes and the deposition of low-k dielectrics, barrier layers, and advanced interconnects.

One of PEALD’s key advantages is its ability to deliver higher film density, lower impurity levels, and superior step coverage in high-aspect-ratio (HAR) structures. These benefits are vital in manufacturing 3D NAND memory, FinFETs, and DRAM, where conventional methods struggle to maintain uniformity. In fact, over 50% of ALD systems deployed in sub-7nm fabs now integrate plasma enhancement. Leading chipmakers, including Intel, TSMC, and Samsung, have already commercialized PEALD in applications such as TiN and TaN barrier layers and dielectric stack formation.

Performance improvements are significant: studies show that PEALD reduces defect density by 30–40% compared to thermal ALD in specific use cases. Additionally, conformality in HAR structures improves by up to 20%, making it a preferred technique for scaling below 5nm. Equipment vendors are also innovating by developing plasma sources with higher uniformity, minimal substrate damage, and broader material compatibility, which is accelerating PEALD’s adoption not just in semiconductors but also in MEMS, photonics, and flexible electronics.

Spatial ALD Expanding into Large-Area Applications

While PEALD dominates advanced node semiconductors, Spatial Atomic Layer Deposition (Spatial ALD) is making waves in large-area and high-throughput applications such as flat-panel displays, solar cells, and flexible electronics. Unlike traditional ALD, which relies on time-separated precursor pulses, Spatial ALD separates precursor zones spatially. This allows substrates to move continuously, dramatically increasing growth rates to 1–10 nm/min, compared to 1–2 Å/cycle with temporal ALD.

This throughput advantage translates into 3–10× higher productivity compared to batch-mode ALD tools. Companies such as Beneq, Encapsulix, and Lotus Applied Technology are at the forefront of commercializing Spatial ALD solutions. Adoption has been particularly strong in OLED encapsulation, where usage has grown more than 25% year-on-year, with major display fabs in Asia deploying Spatial ALD for barrier coatings.

In the solar industry, ALD-deposited passivation layers are delivering 1.2–1.5% efficiency improvements, while flexible substrate coatings benefit from up to 60% fewer defects compared to CVD techniques. These benefits make Spatial ALD an attractive option for roll-to-roll production of OLED displays, flexible solar panels, and thin-film batteries. Ongoing innovation in precursor delivery systems, head design, and web-handling mechanisms is expected to further strengthen its role as a scalable, cost-efficient deposition technique.

Market Segmentation by Type: Thermal ALD Retains Strong Growth

Despite the rise of PEALD and Spatial ALD, Thermal ALD remains the fastest-growing segment due to its simplicity, reliability, and proven performance across diverse industries. By activating precursors with heat rather than plasma, Thermal ALD provides stable and conformal coatings without the risk of plasma-induced substrate damage. This makes it particularly valuable in semiconductor device fabrication, where it is widely used for high-k dielectric deposition, barrier coatings, and metal oxide films.

Thermal ALD is also gaining traction in photovoltaics and battery technologies. For instance, Al₂O₃ dielectric layers deposited using Thermal ALD significantly improve solar cell passivation and efficiency. In energy storage, thin ALD films on electrodes enhance cycle stability and performance, contributing to the development of solid-state and lithium-ion batteries. Beyond electronics, Thermal ALD is increasingly adopted in MEMS and sensors, where precision coatings are critical.

Its low operational complexity and compatibility with a broad range of precursors make it suitable for both high-volume manufacturing and R&D settings. As a result, despite competition from newer ALD variants, Thermal ALD continues to expand its market share.
