Spin-on hardmasks, often abbreviated as SOH, market in 2026 will be driven by the ever-growing intricacy of semiconductor manufacturing, lithography techniques, and multilayer patterning with the requirement for very thin films of materials. Spin-on hardmasks are special materials that are applied to semiconductor wafers in their liquid phase and then transformed into thin and uniform films in preparation for the next steps of pattern transfer. These materials become increasingly important due to increasingly complicated semiconductor manufacturing and the necessity to work with high aspect ratio and smaller feature sizes of devices.

What is SOH Market?

SOH market is the market of materials, formulations and processes applied as hard mask layers in semiconductor manufacturing. Unlike photoresists, which are specifically designed to react on the action during lithography, hardmasks add another layer of protection during pattern transfer and etching.

Why Spin-on Hardmasks Become Increasingly Important in Semiconductor Manufacturing?

Modern semiconductor devices require increasingly sophisticated patterning processes. While a photoresist pattern can be enough for a certain degree of durability during the process of aggressive etching, the process requires very small features transferred through relatively thick layers.

How do Hardmask and Photoresist Differ from Each Other?

Photoresist is a light-sensitive chemical substance used for creating patterns on semiconductors through lithography process. On the other hand, a hardmask can be developed to be able to resist subsequent etching and transfer the patterns to layers below.

Thus, in the most modern processes, the substances can serve complementary purposes. Photoresist helps in defining patterns, while a hardmask will help resist etching when transferring these patterns.

What Factors are Driving SOH Markets in 2026?

First of all, the complexity of semiconductors is a factor that is driving the SOH market. Increasingly complicated semiconductors are needed for AI processors, HPC devices, advanced memories and logic.

According to SEMI, the global semiconductor equipment billings have significantly grown in 2025, with wafer processing equipment being the largest segment of semiconductor manufacturing equipment billings. Moreover, the organization noted further investments in advanced logic, memory and AI-related semiconductors.

How are SOH Materials Used in Advanced Lithography Processes?

Modern lithography requires more complicated approaches to maintain pattern fidelity throughout the entire process. The use of hardmask material may provide additional etch resistance and increase process window of a particular structure.
