A manufacturing method includes depositing a chamber protective layer in a chamber, supplying a first purge gas to the chamber, transferring a substrate to the chamber, the substrate being disposed inside an edge ring on an electrostatic chuck, processing the substrate, supplying a second purge gas to the chamber, transferring the substrate to an outside of the chamber, removing the chamber protective layer, and supplying a third purge gas to the chamber. Variation of the surface roughness of the edge ring may be minimal. A ratio of an edge gas flow rate of gas supplied to an edge of the substrate and the edge ring to a central gas flow rate of gas supplied to a central portion of the substrate in the processing the substrate may be 0.05 to 19. The flow rate ratio may be more than 1 in the supplying the second purge gas.

A wafer processing method includes supplying a first process gas into a wafer processing apparatus, lowering a temperature of the wafer, generating plasma using the first process gas, supplying a second process gas and mixing the second process gas with the plasma, performing a plasma process on the wafer using the plasma and the second process gas, and performing an annealing process on the wafer on which the plasma process has been performed. The lowering of the temperature of the wafer includes increasing an internal pressure of the wafer processing apparatus.

A hollow cathode includes an insulation plate having cathode holes. Bottom electrodes are below the insulation plate. The bottom electrodes define first holes having a width greater than a width of the cathode holes. Top electrodes are at an opposite side of the insulation plate from the bottom electrodes. The top electrodes define second holes aligned with the first holes along a direction orthogonal to the upper surface of the insulation plate.

A chamber has an upper housing and a lower housing and receives a reaction gas. A first plasma source includes electron beam sources providing electron beams into the upper housing to generate an upper plasma. A second plasma source includes holes generating a lower plasma within the holes connecting the upper housing and the lower housing. Radicals of the upper plasma, radicals of the lower plasma, and ions of the lower plasma are provided, through the holes, to the lower housing so that the lower housing has radicals and ions at a predetermined ratio of the ions to the radicals in concentration. The second plasma source divides the chamber into the upper housing and the lower housing. A wafer chuck is positioned in the lower housing to receive a wafer.
