Abstract:
1. A method of fabricating a semiconductor device, comprising: a first step of cleaning a surface of a semiconductor substrate by: introducing a gas containing at least F 2 or HF into a plasma generating chamber of a surface cleaning device having an arrangement in which the plasma generating chamber and a processing chamber are separated from each other by a shower plate, to generate plasma in the plasma generating chamber; and introducing a radical contained in the plasma from the plasma generating chamber into the processing chamber in which the semiconductor substrate is placed through the shower plate while introducing a gas containing at least an H 2 gas or an HF gas into the processing chamber; and a second step of exposing the surface of the semiconductor substrate having been subjected to the first step to a hydride, with the substrate being at a temperature lower than a thermal decomposition temperature of the hydride.
