SiN substrate

VeTek Semiconductor SiN substrate is an advanced ceramic material that has attracted widespread attention for its excellent mechanical, electrical and thermal properties. This ceramic substrate is made of silicon and nitrogen atoms bonded through a specific crystal structure, exhibiting unique strength, durability and heat resistance. SiN substrates are indispensable in high-performance applications such as semiconductor devices, and their properties significantly improve the efficiency and reliability of integrated circuits (ICs), sensors, and microelectromechanical systems (MEMS).

SiN substrates product features：

Excellent thermal conductivity: Thermal management plays an important role in the performance of semiconductor devices. The thermal conductivity of SiN ceramic plate is as high as 130 W/m·K, which can effectively dissipate heat from electronic components and prevent overheating, thereby extending the service life of the equipment.

Chemical stability and corrosion resistance: Silicon Nitride exhibits extremely strong resistance to chemical corrosion and is particularly suitable for use in environments exposed to chemicals or extreme temperatures. Even in environments with corrosive gases, acids and alkalis, SiN substrates maintain their structural integrity, ensuring long-term reliability in industrial applications.

High thermal shock resistance: SiN substrates can withstand rapid temperature changes up to 1200°C without thermal shock or cracking. This property is critical in areas such as power electronics and high-temperature sensors, which are often challenged by sudden temperature changes.

High strength and toughness: Compared with other ceramic materials, the compressive strength of SiN ceramic substrate can reach 600 MPa, showing excellent toughness. This enables it to effectively resist cracking and maintain structural integrity in high-stress and precision-processed semiconductor processes, ensuring mechanical stability.
