Global SOC (Spin on Carbon) Hardmasks Market Strategic Research Report

Scope of the Report

The global SOC (Spin on Carbon) Hardmasks market size is predicted to grow from US$ 142 million in 2025 to US$ 253 million in 2032; it is expected to grow at a CAGR of 8.7% from 2026 to 2032.

Spin-on Carbon (SOC) hardmasks can be used in multilayer lithography processes with high etch resistance, low cost of ownership, low defects, high alignment accuracy, good gap filling and topography planarization. SOC is a high carbon-containing polymer solution. As a coating material, the polymer needs to be dissolved in an organic solvent and insoluble in the upper layer of the coating after curing. The high carbon content (>80%) of the SOC is important for good etch resistance.

Spin-on Carbon (SOC) hardmasks are an increasingly key component of the micro-chip fabrication process. They are frequently used to improve the resists’ selectivity to silicon during plasma etching. Furthermore, as chip architectures become increasingly complex the use of hardmasks to improve the aspect ratio of features in silicon is critical. In this context, the ‘aspect ratio’ is the ratio between the height of a feature on a silicon wafer and its width. For many emerging multi-layer chip architectures, such as tri-layer etch-stacks, a large height to width ratio is required to maintain small lateral features across multiple vertical layers.

Global key players of SOC (Spin on Carbon) hardmasks include Samsung SDI, Merck Group, JSR, Brewer Science, etc. The top three players hold a share over 75%.
