The relationship between ceramics and semiconductors: unsung heroes supporting high-tech development.

1. Why are ceramics able to enter the semiconductor field?

Semiconductor manufacturing processes require extremely high levels of cleanliness and stability. Metal parts are prone to particulate contamination, and plastic parts cannot withstand high temperatures and plasma corrosion. Precision ceramic materials (such as alumina, zirconium oxide, silicon nitride, and aluminum nitride) perfectly fill this gap.

The core characteristics of ceramic materials include:

High insulation: Prevents current leakage and ensures stable signal transmission;

High temperature resistance: Maintains structural strength in environments exceeding 1600℃ (alumina ceramics);

Corrosion resistance: Resists chemical etching gases and plasma erosion;

High purity and low precipitation: Avoids secondary contamination of wafers;

High dimensional accuracy: Meets the equipment assembly requirements of nanoscale processes.

2. Key Applications of Ceramics in Semiconductor Manufacturing

Ceramic components are virtually ubiquitous in semiconductor equipment and manufacturing processes:

Application phase	Ceramic components	Material type
wafer carriers, trays	Aluminum nitride and alumina ceramics	High thermal conductivity and insulation
Etching/Deposition Cavity Liner	Silicon nitride and alumina ceramics	Plasma corrosion resistance
Vacuum suction cup (Chuck)	Alumina and aluminum nitride ceramics	Stable, flat, and wear-resistant
Electrostatic adsorption stage (ESC)	Aluminum nitride ceramics	Excellent thermal conductivity
Temperature measurement and insulation support	alumina ceramics	Good electrical insulation and temperature resistance
Guiding, sealing, and thermal insulation structural components	Zirconia ceramics	High strength and toughness

It can be said that, from core components to auxiliary parts, precision ceramics are the "structural cornerstone" for the reliable operation of semiconductor equipment.

3.The "Deep Bonding" of Ceramics and Semiconductors

As chip manufacturing processes advance from 28nm and 7nm to 3nm and even more advanced nodes, the requirements for equipment durability, cleanliness, and thermal management performance become increasingly stringent, driving the continuous evolution of ceramic materials.

High-purity alumina ceramics: purity ≥99.9%, meeting the requirements for ultra-clean vacuum chambers;

High thermal conductivity aluminum nitride ceramics: thermal conductivity as high as 170–280 W/m·K, aiding in the optimization of thermal control systems;

High-toughness zirconia ceramics: used for mechanical moving parts and precision clamping structures;

Silicon nitride ceramics: combining high strength and low thermal expansion coefficient, suitable for complex working conditions.
