As a non-metallic material, ceramics have excellent physical and chemical properties and therefore are widely used in the semiconductor industry. We will introduce the application fields and specific application cases of ceramics in the semiconductor industry, as well as the advantages and challenges of ceramics.
Where can we found ceramic in semiconductor manufacturing?
1.Electronics packaging
Ceramics are widely used in the housing and substrate of semiconductor devices in the field of electronic packaging. The ceramic shell provides good mechanical protection and thermal conductivity, protecting the device from interference from the external environment. Ceramic substrates are used to connect and support electronic components. Their excellent insulation properties and thermal stability enable electronic components to operate stably in harsh working environments.
2.Circuit Board
Ceramic circuit boards are widely used in high-frequency electronic equipment, such as wireless communication equipment and radar systems. Ceramic circuit boards have low dielectric loss and excellent thermal properties, providing better signal transmission and higher operating frequencies. In addition, ceramic circuit boards also have good dimensional stability and mechanical strength, and can meet the wiring requirements of complex circuits.
3.Heat Sink
The application of ceramics in heat sinks mainly utilizes their excellent thermal conductivity properties. Since semiconductor devices generate a large amount of heat during operation, it needs to be dissipated through a heat sink to ensure the normal operation of the device. Ceramic materials have high thermal conductivity and excellent thermal stability, which can effectively conduct heat to the surface of the radiator and improve heat dissipation efficiency.
