Low Cost Infrared Lamp Heating System for R&D RTP-6

80°C/s high speed annealing possible at low cost.
This infrared lamp heating system with parabolic type reflectors can heat uniformly a wafer of the size up to 6 inches. It is capable of high-speed heat treatment, the most available for the research and development of heat treatment process. Silicide formation in individual semiconductor process and process annealing of compound semiconductor are available.


  • Capable of high speed heat treatment.
  • Capable of high speed cooling with the metal chamber cold-wall Cconstruction.
  • Gas flow after vacuum displacement is also available.
  • Temperature program setting and external signal input is easily executed from a PC.
  • Temperature data during heating can also be displayed on a PC.
  • A quartz protection plate (optional) can be installed in the chamber to prevent contamination.
  • Equipped with various safety measures.
  • Capable of excellent temperature distribution and reproducibility with the 9 zone control.
