Core Functions of Sapphire Lift Pins

 

Sapphire lift pins are critical components in semiconductor and LED manufacturing equipment, primarily used for wafer transfer and positioning.

 

 

1. Wafer Support & Vertical Movement


In thin-film deposition (e.g., MOCVD), etching, or lithography processes, robotic arms actuate sapphire lift pins to elevate from the chamber floor, precisely supporting wafers (e.g., 2/4/6-inch substrates) while maintaining level positioning to facilitate loading and unloading operations.

 

 

2. Stable Performance in High-Temperature Environments


Sapphire (single-crystal Al₂O₃) boasts an ultra-high melting point of 2050°C, enabling prolonged operation above 1000°C (e.g., GaN epitaxial growth) without the risk of thermal deformation or wafer contamination typical of metal pins.

 

 

3. Chemical Inertness for Process Integrity


With exceptional resistance to acids, alkalis, and plasma environments, sapphire prevents impurity release during etching or CVD processes, ensuring manufacturing purity (particularly critical for wide-bandgap semiconductors like SiC/GaN).

 

 


 

Key Advantages
 

 

1. Ultra-Low Contamination: Compared to metal (e.g., molybdenum) or ceramic (e.g., AlN) alternatives, sapphire generates minimal particulate shedding, meeting Class 10 cleanroom standards.

 

2. Exceptional Hardness (Mohs 9): Surface scratch resistance extends service life beyond 100,000 cycles—5-8 times longer than quartz pins.

 

3. Matched Thermal Expansion Coefficient: Close alignment with SiC/GaN wafers (~7.5×10⁻⁶/°C) minimizes thermal stress-induced warping or cracking.

Typical Applications of Sapphire Lift Pins

 

1. LED Epitaxial Wafer Production: Supports sapphire substrates during GaN epitaxial growth in MOCVD reactors.

 

 

2. Power Semiconductor Fabrication: Enables high-temperature ion implantation or annealing processes for SiC wafers.

 

 

3. Advanced Packaging: Ensures micron-level precision positioning for ultra-thin wafers (thickness <100μm) in wafer-level packaging (WLP).
