Silicon nitride wafers (Si3N4 wafers) are an important semiconductor and optical material with a wide range of uses, a complex production process, and special techniques required in the cutting process.
Uses of silicon nitride wafers:
Microelectronic packaging: silicon nitride is used as an insulating layer for chip protection and packaging.
MEMS (Micro-Electro-Mechanical Systems): due to its mechanical strength and high-temperature resistance properties, it is suitable for the manufacture of tiny mechanical structures.
Optical applications: Due to its good infrared transmittance, silicon nitride wafers can be used to manufacture optical windows and lenses. Silicon nitride has high transmittance and low absorption, making it suitable for the manufacture of optical devices such as optical waveguides, optical switches and laser diodes.
Protective Coatings: Silicon nitride is used as a protective coating for tools, molds and other industrial components.
Semiconductor devices: Silicon nitride can be used as a base material for high electron mobility transistors (HEMTs) and other high-frequency, high-power electronic devices.
Solar Cells: Used as an anti-reflective layer in silicon-based solar cells to improve light absorption efficiency.
Insulating layer: Due to its excellent insulating properties, silicon nitride is often used as an insulating and dielectric layer in integrated circuits.
