- the susceptor 200 can be rotated without using a separate susceptor 200 rotating device using air or gas, the structure of the substrate processing apparatus is simplified, and the power and energy used for processing the substrate. It has the effect of reducing the consumption of.
- vibration and noise generated when the susceptor 200 is rotated may be suppressed to prevent shaking of the substrate seated on the upper surface of the susceptor 200, uneven deposition on the substrate, and occurrence of etching.
- the susceptor can be rotated without using a separate susceptor rotating device using air or gas, thereby simplifying the structure of the substrate processing apparatus and reducing power and energy consumption used for substrate processing. It works. Therefore, there is industrial applicability.
