Abstract:
1. An apparatus for manufacturing a semiconductor device, comprising: a single reaction chamber having an outlet; a susceptor in the single reaction chamber to hold a substrate thereon; a source material container for supplying the single reaction chamber with a source material; a liquid mass flow controller connected to the source material container; a plurality of vaporizers connected to the liquid mass flow controller for receiving flow from the liquid mass flow controller; a plurality of separate source gas injectors, each of the plurality of separate source gas injectors being connected to a respective one of the plurality of vaporizers to provide a separate source gas flow path from each vaporizer into said single reaction chamber, one end of each separate source gas injector projecting into the single reaction chamber; a reactive gas container for supplying the single reaction chamber with a reactive gas; and a plurality of reactive gas injectors connected to the reactive gas container, one end of each reactive gas injector projecting into the single reaction chamber; wherein the single reaction chamber is configured to receive the reactive gas from the reactive gas container and the source gas from the source material container for depositing a thin film on a semiconductor device; and wherein the plurality of vaporizers and the plurality of source gas injectors are connected to each other in such a manner that the vapor from each vaporizer is injected separately and simultaneously into the reaction chamber and mixes with vapor from the other vaporizers after entering the reaction chamber, and wherein the vapor from each vaporizer can mix with vapor from the other vaporizers only after entering the reaction chamber.
