Classification: CPC H  C  G | IPC C  G  H

Claim 50:
51. A substrate processing apparatus comprising:
a process chamber configured to process a substrate including a first pattern, the first pattern having a first width and a first height;
a source gas supplying device configured to supply a source gas to the process chamber;
an oxygen-containing gas supplying device configured to supply an oxygen-containing gas to the process chamber;
a plasma generating device configured to generate a given plasma in the process chamber;
a heating device configured to heat the substrate; and
a controller configured to:
(a) trim the first pattern to form a second pattern in the process chamber using a first oxygen-containing gas plasma generated by the plasma generating device while causing the heating device to heat the substrate at a first temperature of 100 degrees Celsius or less, the second pattern having a second width and a second height;
(b) cause the heating device to heat the substrate at a second temperature of room temperature to 300 degrees C.; and
(c) form an oxide film on the second pattern in the process chamber by adsorbing the source gas on the second pattern and oxidizing the source gas using a second oxygen-containing gas plasma generated by the plasma generating device while causing the heating device to heat the substrate at the second temperature, the adsorbing the source gas and the oxidizing the source gas being performed alternately, and generating the second oxygen-containing gas plasma being performed intermittently.
