Abstract:
1. A gas nozzle system for depositing material in a reactor chamber that accommodates at least two susceptors situated inside the reactor chamber, comprising: a gas-inlet component situated inside the gas nozzle system, wherein inner walls of the gas-inlet component form a first enclosed space that has at least one input-opening that opens to the reactor chamber, and wherein the gas-inlet component is configured to inject precursor gases into the reactor chamber via the input-opening; and a gas-outlet component stacked around and substantially enclosing the gas-inlet component, wherein inner walls of the gas-outlet component and outer walls of the gas-inlet component form a second enclosed space that has at least one output-opening that open to the reactor chamber, wherein the gas-outlet component is configured to output exhaust gases from the reactor chamber via the output-openings, wherein the output-opening is situated around the input-opening, and wherein the input-opening and the output-opening surrounding the input-opening are configured to open alternately, thereby enabling a uniform material deposition; wherein the gas-nozzle system is coupled to the susceptors in the reactor chamber in such a way that the gas-inlet component injects precursor gas into a narrow channel formed by two susceptors facing each other situated within the reactor chamber.
