ASM reports that the ALD market is expected to grow by a CAGR of 16%-20% from 2020 to 2025

ASM International presented its Q2/2022 report in July and a new record orders of EUR 943 million driven by robust new node spending in logic/foundry and by recent wins in memory, particularly for ALD gap-fill in 3D-NAND and continued adoption of HKMG in DRAM.

ASM focuses on the single wafer market so the numbers presented does typically not include ALD Large Batch, which is dominated by Tokyo Electron and Kokusai. Back in 1999, ASM acquired Finnish legendary ALD company Microchemistry and its Pulsar 2000 cross-flow chamber ALD technology, which later took the market as the 300 mm version Pulsar 3000 for HfO2 in HKMG at Intel, TSMC, Samsung Globalfoundries, and others. Now it is interesting to follow how the success story continues also for DRAM HKMG. Since then, ASM has added PEALD from Genitech (South Korea) and Large Batch ALD (A412), and many other ALD process technologies. See recent announcements 2022 here:

BALD Engineering - Born in Finland, Born to ALD: ASM International launches TENZA ALD Quad Chambers for silicon oxide gap-fill and liners on the XP8 platform

BALD Engineering - Born in Finland, Born to ALD: ASM Internaltional launces new 300 mm Vertical batch for LPCVD and ALD

So it is interesting that ASM has launched a new ALD Batch platform based on the now rather old A412 and the new TENZA to capture growth in Gap-fill - a stronghold for Lam Research.

The ALD market is driven by increased wafer starts in 300 mm for sub 45 nm nodes, 3DNAND and DRAM, and the ongoing fab expansions world-wide.

• TechInsights expects WFE to increase by 21% in 2022 (July 2022)
• Strongest growth in leading-edge nodes, spending on 7nm and below expected to grow from ~25% of WFE in 2020 to ~42% of WFE in 2025
• Gartner expects total WFE to increase by 19% in 2022 (July 2022)

You can compare the TECHCET forecast on precursors where you can see high y-o-y growth going through 2021 and 2023 driven by increased 300 mm wafer production and a slowdown in 2023.
