Semiconductor Wafer Processing

Silicon Carbide Components

 
Saint Gobain Specialty Ceramics' products allow customers to solve tough problems in thermal and chemical processing, industrial metrology, temperature sensing, brazing, mechanical seals, semi-conductor processing, sandblasting, and renewable energy generation applications.

A range of Hexoloy® SA and SG components can be used in semiconductor wafer processing equipment, including vacuum chucks, chemical mechanical polishing (CMP) blocks and wafer carrier trays.

 

These applications take advantage of Hexoloy silicon carbide's thermal expansion match to silicon, high elastic modulus, chemical inertness, and high thermal conductivity. Hexoloy silicon carbide is well suited as a structural material for low mass wafer carrier components, and rigid dimensionally stable platforms with exceptional flatness for wafer grinding, lapping, and polishing.

 

Silit® SK SiSiC and Advancer® NB SiC materials are used in the air-bearing stages of semiconductor metrology positioning equipment.

FAQ

Does Saint-Gobain Performance Ceramics & Refractories offer products for semiconductor wafer inspection metrology equipment?

Silit® SiSiC and Advancer® NB SiC products are used in the construction of air-bearing stages for positioning equipment.

How is sintered silicon carbide typically used in semiconductor wafer processing applications?

Hexoloy® sintered silicon carbide can be used in a wide range of components, including:

  • Vacuum chucks
  • Reactor tubes for thermal oxidation
  • Wafer grinding and polishing plates
  • Thermocouple protection tubes
  • Wafer carrier trays
  • Clamps and lift pins
  • Sputtering targets

Is Hexoloy® SiC pure enough to be used in semiconductor wafer processing?

Hexoloy® sintered silicon carbide is essentially a single-phase material with at least 98% SiC.

 

At this purity, Hexoloy® can be successfully used at low to moderate temperatures in wafer contact applications, and up to 1,300°C in non-contact applications.
