Ceramic Lift Pins for Semiconductor Wafer Manufacturing

Ceramic lift pins are essential components in semiconductor manufacturing wafer handling systems.

They play the critical role of supporting the transfer of process wafers into process modules within fabrication equipment. Fralock manufactures top quality lift pins made from high purity alumina and sapphire ceramics, utilizing robotics and automated grinding equipment to ensure consistency and tolerance compliances.

Our lift pins are designed with precision to ensure proper contact and support for the delicate semiconductor wafers. The design accounts for cleanliness and chemical resistance to meet the stringent requirements of semiconductor manufacturing environments.

Ceramic materials are preferred for lift pins due to their excellent properties:

  • Superior chemical resistance - high resistance to corrosive chemicals and gases
  • Dimensional stability
  • Wear resistance
  • Tight tolerancing
  • Thermal stability - Ceramics can withstand elevated temperatures without compromising their structural integrity, ensuring reliable performance
  • High Hardness - The hardness of ceramics ensures durability and resistance to wear, providing a longer lifespan in comparison to alternative materials.
  • Low particle generation
  • Customization
