Abstract:
A combinatorial molecular layer epitaxy apparatus comprising:a common chamber having pressure therein controllable; one or more conveyable substrate heating units having a substrate holder for holding one or more substrates in the common chamber; and a plurality of process conducting chambers having pressure therein controllable and provided to correspond to the substrate heating units, said process conducting chambers including a growth chamber which has a multiple raw material supply means for supplying raw materials onto a said substrate held by a said substrate heating unit, a gas supply means for feeding a gas onto a surface of the substrate, and an instantaneous observation means for instantaneously observing epitaxial growth of monomolecular layers for each of the layers on the substrate surface, thereby permitting growth temperature, pressure and supply of the raw materials to be controlled for each of the substrates and producing a group of substances caused each to grow epitaxially in an individual monomolecular layer and brought together for each of the substrates, systematically in accordance with indications of the instantaneous observation means.
