Silicon Nitride (Si3N4) substrates
We carry a wide selection of Silicon Nitride (Si₃N₄) substrates in stock and ready to ship. If you require a custom size or thickness, or if you are requesting a high-volume quote, simply contact us and our team will be happy to assist.
Key Features of Silicon Nitride (Si₃N₄) Substrates
-
High-strength Silicon Nitride substrate offering exceptional durability and bending strength — approximately twice as strong as Alumina and Aluminum Nitride (AlN) substrates
-
High thermal conductivity ceramic substrate with up to 3× higher heat transfer capability compared to Alumina and ZTA, ideal for high-power electronic devices
-
Excellent electrical insulation performance featuring high dielectric breakdown voltage and very high surface and volume resistivity
-
Low coefficient of thermal expansion (CTE) close to silicon, reducing thermal mismatch stress in semiconductor, power module, and LED applications
-
Stable performance in extreme environments — resists thermal shock, high temperatures, mechanical stress, and corrosive conditions
-
Ideal for high-power and high-reliability applications, including IGBT modules, automotive power electronics, aerospace electronics, RF power amplifiers, and industrial energy systems
-
Available in multiple sizes and thicknesses, with custom dimensions and high-volume production supported upon request
