Zirconia Ceramic Wafer Carriers And Cleaning Jigs: Precision Support Solutions For Semiconductor And Photovoltaic Industries

Introduction

Zirconia ceramic wafer carriers and cleaning jigs are high-precision auxiliary tools specifically designed for semiconductor wafer manufacturing and photovoltaic silicon processing. Manufactured from high-purity, nano-grade zirconia (ZrO₂) through phase transformation toughening technology and precision machining, they exhibit exceptional dimensional stability, excellent chemical corrosion resistance, and outstanding mechanical strength. These components operate reliably in high-temperature, highly corrosive, and ultra-clean environments, ensuring zero contamination and zero damage support for wafers and silicon sheets during manufacturing processes.

Applications

• Semiconductor Wafer Manufacturing: Diffusion process boats, CVD trays, etching fixtures, ion implantation carriers

• Photovoltaic Silicon Processing: Cleaning baskets, texturing supports, PECVD trays, screen printing positioning jigs

• Display Panel Manufacturing: OLED evaporation mask supports, glass substrate transfer arms

• Precision Testing Equipment: Probe station chucks, microscope stages, thickness measurement tooling

Advantages

1. Ultra-High Dimensional Stability: Thermal expansion coefficient close to silicon (4.2×10⁻⁶/K), ensuring no displacement deviation during high-temperature processes

2. Excellent Chemical Resistance: Resists corrosion from all semiconductor-grade chemicals including HF, HNO₃, and KOH

3. Extremely Low Contamination Risk: Metal ion release <0.1ppb, meeting Class 10 cleanroom requirements

4. Exceptional Wear Life: Hardness >1300HV, service life exceeds PEEK materials by more than 10 times

5. Multi-functional Integration: Can incorporate special functional requirements such as conductivity, insulation, and magnetism
