Abstract:
1. A method of manufacturing a semiconductor device, comprising: placing a substrate on a substrate mounting table disposed in a substrate processing chamber via a substrate transfer port, the substrate including grooves having high aspect ratios with a silicon-containing layer being disposed thereon; exhausting a gas while supplying an oxygen gas into a plasma generation space at an upper portion of the substrate processing chamber, the plasma generation space communicating with a space; generating a plasma in the plasma generation space by applying an electric power to a resonance coil of an inductive coupling structure disposed in a helix shape around the plasma generation space to generate an induced electric field for a plasma excitation of the oxygen gas, the electric power having a wavelength equal to an integer multiple of a sum of electrical lengths of the resonance coil and a waveform adjustment circuit connected to the resonance coil; and oxidizing the silicon-containing layer disposed on the grooves having high aspect ratios using the plasma, wherein inner walls of the grooves are oxidized during the oxidizing, such that thicknesses of oxide films formed on bottom portions and side portions of the grooves are uniform.
