The world runs on microchips. From smartphones and electric vehicles to satellites and AI supercomputers, chips are everywhere. And while we often talk about transistors, lithography, and chip design, there’s another category of materials working behind the scenes to make it all possible Spin on Dielectrics (SOD) and Spin on Hardmask (SOH) Materials Market.
Though they may sound like niche substances, these two material types are foundational to how chips are made today—and how they’ll be made tomorrow.
Why Do Spin-On Materials Matter?
Modern semiconductors are tiny, complex, and built with extreme precision. Layers of metal and silicon are stacked and patterned to create transistors and circuits. That’s where SOD and SOH materials come in:
-
Spin-on Dielectrics are insulating materials applied in thin layers to separate electrical pathways. They help prevent signals from interfering with each other and improve energy efficiency.
-
Spin-on Hardmasks are used during the chipmaking process to protect certain areas of the silicon while others are etched away. They act like a stencil during manufacturing, ensuring patterns are created accurately.
These materials are “spun on” wafers in liquid form and then baked into solid films, which is why they’re called “spin-on.”
Current Market Snapshot
As of 2024, the global market for SOD and SOH materials is worth around $1.25 billion. By 2033, it’s expected to grow to $2.45 billion, with a steady 8.2% compound annual growth rate (CAGR).
Why the growth? Simply put, chips are getting smaller and more powerful, and they need better materials to keep up. Spin-on materials help solve critical challenges like reducing power usage, controlling heat, and enabling ultra-precise manufacturing at the nanoscale.
How Are These Materials Used?
🧠 In Chip Manufacturing:
In the early stages of chip fabrication, layers of materials are applied, patterned, and etched. Spin-on materials help manage that layering and patterning—crucial for chips at 5nm, 3nm, and beyond.
📦 In Advanced Packaging:
Packaging is how chips are connected to the outside world. As chips become stacked or arranged side-by-side (in “chiplets”), spin-on materials help protect them and maintain electrical isolation.
Deposition Technologies
To apply these materials, several techniques are used:
-
Spin Coating: The material is dispensed on a spinning wafer, creating a thin and even layer—this is the most common method.
-
Chemical Vapor Deposition (CVD): Used when materials need to cover more complex shapes and surfaces.
-
Physical Vapor Deposition (PVD): Mainly for hardmask materials that require durable, tightly controlled films.
Each method has pros and cons, but spin coating remains the go-to for many SOD and SOH applications due to its simplicity and cost-effectiveness.
