Patent ID: 7041582

Claim:
A method of manufacturing a semiconductor device, comprising: a) providing a semiconductor substrate on which various components for forming a semiconductor device are formed; b) supplying a precursor containing a source into a deposition chamber to adsorb the source on the semiconductor substrate; c) removing the precursor which is not absorbed on the semiconductor substrate and remains in the deposition chamber to purify the interior of the deposition chamber, wherein other impurities are removed with the precursor; d) supplying a reaction gas into the deposition chamber to form an atomic layer through reaction with the source adsorbed on the semiconductor substrate; e) removing the reaction gas which is not reacted with the source to purify the interior of the deposition chamber, wherein reaction byproducts are removed with the reaction gas; f) supplying an additive gas into the deposition chamber in order to make the atomic layer an amorphous state; and g) removing the additive gas to purify the interior of the deposition chamber.
