Patent ID: 7981815

Claim:
A producing method of a semiconductor device comprising the steps of: loading at least one substrate into a processing chamber comprising a buffer chamber and electrodes for generating hydrogen plasma, the electrodes being disposed in the buffer chamber and the buffer chamber having holes for supplying hydrogen plasma to the processing chamber; forming a metal oxide film or a silicon oxide film on a surface of the substrate by repeatedly supplying a metal compound or a silicon compound, each of which is a first material, an oxide material which is a second material including an oxygen atom, and the hydrogen plasma which is a third material, into the processing chamber predetermined times; and unloading the substrate from the processing chamber, wherein a hydrogen gas is supplied to the buffer chamber so that the plasma hydrogen is generated with the electrodes therein and supplied through the holes to the processing chamber to form the metal oxide film or the silicon oxide film on the surface of the substrate, and an OH-group is substituted for a reaction site on the surface of the substrate by supplying the second material and the third material into the processing chamber.
