[0002] In the thin film deposition or oxidation process of a semiconductor wafer, the semiconductor wafer is usually placed in a reaction chamber, heated to a certain temperature and subjected to corresponding reactions or treatments under a certain air pressure. For the heating method, there are induction heating, resistance heating and thermal radiation heating methods. Among them, the resistance method mainly connects a resistor in series between electrodes, and converts electrical energy into heat energy through the resistor, so that the semiconductor wafer in the reaction chamber is maintained at a certain temperature.

[0003] At the same time, for a silicon carbide crystal or wafer, in order to eliminate lattice defects, a high-temperature annealing treatment is also required, that is, the silicon carbide crystal or wafer needs to be heated to above 1500 °C and maintained for a certain time, which can also adopt the resistance heating method.

[0004] If the resistance heating method is adopted, the industry usually sets the heating structure and the wafer support structure as two independent structures, which will lead to the problems of low utilization rate of the internal space of the equipment and complex structure. Especially in the case of limited cavity space, designing two sets of structures separately will further increase the design complexity and is not conducive to reducing the overall cost of the equipment.

[0012] In one embodiment, there are multiple groups of heating plates, which are parallelly distributed in the vertical direction, and the heating plates are graphite plates.

[0013] Further, the support columns are located in front of the electrode heads of the electrode columns.
