Abstract A method of producing compounds which comprises the steps of separately vaporizing a plurality of substances containing the component elements of a desired compound and placed in a plurality of crucibles to form vapors of the substances, mixing the vapors in a heated mixing chamber to form a mixed vapor, jetting the mixed vapor into a vacuum region to form clusters, ionizing the clusters to form cluster ions, and accelerating the cluster ions to make them impinge on a substrate. An apparatus for producing compounds which comprises a plurality of crucibles for separately vaporizing substances containing the component elements of a desired compound to form vapors of the substances, a mixing chamber for heating and mixing the vapors introduced therein to form a mixed vapor, the mixing chamber having at least one injection hole for jetting the mixed vapor into a vacuum region, communication pipes for connecting the mixing chamber to the crucibles, an ionization chamber for ionizing clusters produced from the mixed vapor jetted from the mixing chamber, means for accelerating cluster ions produced in the ionization chamber and making them impinge on a substrate, and a substrate holder for holding the substrate.
An apparatus for producing compounds from at least three substances, said apparatus comprising: one crucible for each of said substances, each of said crucibles adapted to hold one said substance; means for individually heating each said crucible and vaporizing said substances contained therein; a mixing chamber for heating and mixing said vapors to form a mixed vapor, said mixing chamber including heating means therefor; at least one injection hole in said mixing chamber for jetting said mixed vapor into a vacuum region; communication pipes connecting said mixing chamber to each of said crucibles, each said communication pipe including heating means in the vicinity of said mixing chamber and a nozzle portion having a narrowed diameter at the end of said pipe communicating with the inlet of said mixing chamber; and a substrate holder located in the vacuum region and in the path of said jetted vapor and adapted to hold a substrate on which are deposited clusters produced from said mixed vapor.
