Patent ID: 8851012

Claim:
A vapor deposition reactor for depositing a thin film on a substrate, comprising: a first electrode comprising a body formed with a first channel and an opening, at least one first injection hole connected to the first channel and reaction space located away from the substrate; and a second electrode placed in the reaction space formed in the body of the first electrode, part of the second electrode facing away from the substrate and surrounded by the body of the first electrode to generate plasma or pulse discharge within the reaction space but part of the second electrode facing the substrate not surrounded by the body of the first electrode and communicating with the substrate via the opening, a width of the second electrode along a direction of relative movement between the vapor deposition reactor and the substrate is smaller than a width of the opening in the direction, a material injected into the reaction space between the first electrode and the second electrode via the first channel and the at least one first injection hole, the second electrode comprising: a platform extending longitudinally in a direction parallel to a top surface of the substrate, and at least one protrusion formed on the platform for generating the plasma or pulse discharge responsive to applying a voltage difference across the first electrode and the second electrode.
