Semiconductor ceramics refer to ceramics with semiconductor properties and a conductivity of approximately 10 ^-6~10 ⁵ S/m. The conductivity of semiconductor ceramics changes significantly with changes in external conditions (temperature, light, electric field, atmosphere, and temperature, etc.), so the changes in physical quantities of the external environment can be converted into electrical signals to produce sensitive components for various purposes.

Product Applications

Semiconductor crucibles
In the highly precise field of semiconductor manufacturing, which has strict requirements for material purity, boron nitride ceramic crucibles play a crucial role. Because semiconductor materials, during the melting process, have extremely high requirements for the crucible's high-temperature resistance, chemical stability, and purity. Boron nitride ceramic crucibles possess excellent high-temperature characteristics and can withstand the high-temperature environment during semiconductor material melting without deformation or decomposition, ensuring smooth melting.

Diffusion Barrier Layer
In the complex process flow of semiconductor manufacturing, the control of impurity diffusion is critical. Boron nitride ceramics, with their unique crystal structure and chemical properties, have become ideal diffusion barrier materials. In high-temperature processes, it can form a dense and stable barrier layer, precisely preventing the diffusion of specific impurities into critical areas of semiconductor devices, avoiding device performance degradation caused by impurity diffusion.

Insulating Layer
The operation of semiconductor devices often faces extreme working conditions such as high temperature and high vacuum, which places extremely high demands on insulating materials. Boron nitride ceramics stand out with their excellent electrical insulation performance. Even in high-temperature environments, its internal electronic structure remains stable, effectively preventing current leakage and ensuring the normal operation of the device.

High-Performance Boron Nitride-Based Semiconductor Materials
As semiconductor technology continues to develop towards high performance and miniaturization, the demand for new semiconductor materials is becoming increasingly urgent. Boron nitride ceramics provide an important foundation for the preparation of high-performance boron nitride-based semiconductor materials. Taking boron nitride nanowires as an example, through special preparation processes, starting from boron nitride ceramics, nanowire structures with unique electrical, optical, and mechanical properties can be prepared.
