AI Technical Summary
In the nozzle unit within the plasma reaction chamber, the generation of plasma leads to the deposition of metallic contaminants, a problem that is difficult to prevent effectively with existing technologies.
By setting a first electrode and a second electrode in a substrate processing apparatus and providing a voltage greater than that of the first electrode to the second electrode to form plasma, contaminants in the nozzle unit are removed using plasma cleaning gas, which includes Ar, CF4 and O2, with a flow rate ratio of Ar>CF4>O2.
It effectively reduces metal contamination in the nozzle unit and gas injection orifice, improving the cleanliness of substrate processing and the lifespan of the device.
