Patent ID: 8333839

Claim:
A vapor deposition reactor being configured to make a substrate pass by the reactor through a relative motion between the substrate and the reactor in a non-contact state, comprising: a first injection unit having a first space for receiving a precursor or a reactant and exposing the substrate to the precursor or reactant, the precursor or reactant is supplied to the first space through a precursor or reactant supply channel opening into the first space; a first exhaust unit having a second space for receiving a purge gas and exposing the substrate to the purge gas, the purge gas is supplied to the second space through a purge gas supply channel opening into the second space, the first exhaust unit exhausting the precursor or reactant and the purge gas by pumping the precursor or reactant and the purge gas through an exhaust channel opening into the second space; a second injection unit having a third space for receiving a reactant and exposing the substrate to the reactant, the reactant is supplied to the third space through a reactant supply channel opening into the third space; and a second exhaust unit having a fourth space for receiving the purge gas and exposing the substrate to the purge gas through a purge gas supply channel opening into the fourth space, the second exhaust unit exhausting the reactant and the purge gas by pumping the reactant and the purge gas through an exhaust channel opening into the fourth space; wherein the first injection unit, the first exhaust unit, the second injection unit and the second exhaust unit are arranged along a direction of the relative motion between the substrate and the reactor and include guard barriers to control the flow of the precursor, reactant, or purge gas between the first, second, third and fourth spaces; and wherein deposition conditions are varied according to a pressure in the first injection unit and the second injection unit.
