Abstract: A method of vaporizing a solid organometallic compound in which the method comprises filling the solid organometallic compound into a container, introducing a carrier gas to the container and taking out the gas containing the organometallic compound, wherein the solid organometallic compound is in the form of pellets and contains an inert support.

Abstract: An apparatus of supplying an organometallic compound comprising a vessel into which a solid organometallic compound at room temperature is placed and a carrier gas to sublimate the organometallic compound is supported, a supporter plate capable of maintaining an organometallic compound supported on an inert support in the lower part of the vessel with passing a carrier gas therethrough, a carrier gas inlet in the upper part of the vessel, and a carrier gas outlet downward of the supporter plate of being the bottom part of the vessel are disposed, and wherein the carrier gas is passed through the organometallic compound supported on the inert support loaded on the supporter plate from the above downward, is provided.
