Why does the semiconductor industry need to use industrial ceramics?
Introduction
Does the semiconductor industry need industrial ceramics? The answer is yes! With the rapid development of the semiconductor industry, from wafer manufacturing and packaging testing to power devices and RF modules, the high-temperature, high-power, and high-frequency operating conditions place extremely high demands on materials. In these critical processes, industrial ceramics have become an indispensable material for semiconductor equipment and electronic components.

1. Why is the semiconductor industry inseparable from industrial ceramics?
Semiconductor equipment has three core requirements for materials:
High-Temperature Stability
High-temperature environments of 200–800℃ are frequently encountered during manufacturing processes.
Industrial ceramics can withstand high temperatures without deformation.
High Insulation
Semiconductor electronic control and high-voltage testing equipment have stringent insulation requirements.
Ceramics such as alumina and aluminum nitride have resistivity as high as 10¹⁴ Ω·cm.
Thermal Conductivity and Dissipation Capacity
High-power modules require efficient heat dissipation.
Aluminum nitride ceramics have a thermal conductivity of up to 170 W/m·K.
In addition, industrial ceramics also possess:
Corrosion Resistance
Wear Resistance
Precision Machining Capability
High Dimensional Stability
These properties are difficult to simultaneously meet with traditional metals, plastics, or glass materials.
2. Industrial ceramic materials commonly used in the semiconductor industry
| Material | characteristic | Typical applications |
|---|---|---|
| Alumina ceramics (Al₂O₃) | High insulation (>25KV/mm), high wear resistance, and high cost performance. | Substrate, support frame, insulating bushing |
| Aluminum nitride ceramics (AlN) | High thermal conductivity (≥170W/MK), insulating, thermally matched silicon chip | Power module substrate, LED substrate, heat dissipation structure |
| Silicon nitride ceramics (Si₃N₄) | High strength, thermal shock resistant (≥500△T.℃), lightweight | High-speed bearings, mechanical seals, precision support components |
| Zirconia ceramics (ZrO₂) | High toughness (≥9 MPa·1½), wear-resistant, and impact-resistant. | Valve core, plunger, precision structural components |
