  • Basic Equipment Information
  • Operating Principle
  • Typical Application Case
Main Applications

1. High-quality dry oxidation of silicon dioxide (SiO₂), typically for films below 300 nm;

2. Wet oxidation for thick silicon dioxide films, ranging from 300 nm to 3 μm;

3. Thermal annealing processes below 1100°C.

 

Process / Testing Capabilities

  • Dry oxidation for high-quality SiO₂ films (below 300 nm);
  • Wet oxidation for thick SiO₂ films (300 nm to 3 μm);
  • Thermal annealing processes below 1100°C.

 

Technical Specifications

  • Compatible with wafers up to 6 inches (and smaller sizes);
  • Temperature range: 300°C to 1100°C;
  • Heating rate: 10°C/min;
  • Dry oxidation using oxygen (O₂) process;
  • Wet oxidation using a steam generator (steamer).

Dry oxidation is achieved by introducing oxygen (O₂) into the chamber, while wet oxidation is carried out using steam generated by a steam generator. The quartz chamber is rapidly heated بواسطة the heater system, and nitrogen (N₂) can be used as an inert gas to enable high-temperature annealing processes.
