Claim 0:
1. A method of fabricating a semiconductor device, comprising:
providing a precursor and a carrier gas on a substrate in a chamber; and
providing a reaction gas, which is reacted with the precursor, on the substrate to form a thin film on the substrate through reaction with the precursor,
wherein the providing the precursor and the carrier gas comprises:
supplying the carrier gas into a precursor passage space between a supporting membrane of an inner container and an inner bottom surface of an outer container, the inner container containing a precursor source;
providing the carrier gas to the precursor source on the supporting membrane through pores of the supporting membrane; and
obtaining the precursor through the pores using the carrier gas, without a reduction in supply pressures of the carrier gas and the precursor according to consumption of the precursor source in the inner container.
