Introduction of real substrate temperature measurement technology:

As shown in the figure above, the heat radiated by the array halogen lamp reaches the surface of the sample through the quartz window, and the sample is heated. The traditional rapid annealing furnace uses a thermocouple to measure the substrate temperature. Because the thermocouple is at a certain distance from the substrate, the measurement is not the substrate. The real temperature of the chip must be temperature compensated.

The halogen lamp RTP annealing furnace uses a dedicated flake-like Real T/C KIT for temperature measurement, as shown in the figure above, the contact thermometer is connected to the flake-like Real T/C KIT. The flake-like Real T/C KIT is located very close to the sample above when working, the array halogen lamp radiates heat to the sample surface through the quartz window, the sample is heated, and the flake-like Real T/C KIT is heated at the same time. Because the substrate is very close to the Real T/C KIT, there will be heat transfer between them, and the thermal equilibrium will be quickly reached, so the temperature measured by the flake-like Real T/C KIT is infinitely close to the real temperature of the substrate, thus realizing the real measurement of the substrate temperature.
