A method of manufacturing an organic light-emitting display apparatus, the method comprising the steps of:
- preparing a deposition target in which an organic light-emitting portion is formed on a substrate;
- forming a pre-encapsulation layer for encapsulating the organic light-emitting portion by using a facing target sputtering apparatus;
- and
- forming an encapsulation layer by performing a plasma surface process on the pre-encapsulation layer by using the facing target sputtering apparatus;
- wherein the facing target sputtering apparatus comprises:
- a chamber in which a mounting portion for accommodating the deposition target is provided;
- a gas supply portion facing the mounting portion and supplying gas to the chamber;
- a first target portion and a second target portion disposed in the chamber and facing each other;
- and
- an induced magnetic field coil surrounding the exterior of the chamber.
