Abstract
A vapor deposition apparatus for forming a deposition layer on a substrate includes a supply unit that is supplied with a first raw gas to form the deposition layer and an auxiliary gas, wherein the auxiliary gas does not constitute a raw material to form the deposition layer, a reaction space that is connected to the supply unit to be supplied with the first raw gas and the auxiliary gas, a plasma generator in the reaction space to convert at least a portion of the first raw gas into a radical form, and a first injection portion that is connected to the reaction space and that supplies at least a radical material of the first raw gas toward the substrate.
Claims6
A deposition method for forming a deposition layer on a substrate, the method comprising:
- supplying a first raw gas to form the deposition layer and an auxiliary gas, wherein the auxiliary gas includes helium or neon and does not constitute a raw material to form the deposition layer, from a supply unit to a reaction space;
- generating plasma by operating a plasma generator disposed in the reaction space to convert at least a portion of the first raw gas into a first raw material having a radical form, wherein generating the plasma is carried out at an enemy below a first ionization enemy of the auxiliary gas such that the auxiliary gas remains substantially neutral when the first raw gas is converted into the first raw material in the radical form;
- supplying the first raw material in the radical form and the auxiliary gas through a connecting passage to an injection portion, wherein the connecting passage is between the reaction space and the injection portion, the connecting passage having a narrower width than the injection portion and the reaction space such that the raw gas and the auxiliary gas are induced to sufficiently stay in the reaction space to convert at least the portion of the first raw gas into the first raw material having the radical form;
- and
- supplying the first raw material in the radical form and the auxiliary gas from the injection portion to the substrate.
A method of manufacturing an organic light-emitting display apparatus including a substrate, a first electrode, an intermediate layer including an organic emission layer, a second electrode, and an encapsulation layer by operating a vapor deposition apparatus, the method comprising:
- forming at least one thin film of the organic light-emitting display apparatus, wherein forming the at least one thin film includes:
- positioning the substrate such that the substrate corresponds to the vapor deposition apparatus;
- supplying a first raw gas for forming a deposition layer and an auxiliary gas, wherein the auxiliary gas includes helium or neon and does not constitute a raw material to form the deposition layer, from a supply unit of the vapor deposition apparatus to a reaction space;
- generating plasma by operating a plasma generator disposed in the reaction space to convert at least a portion of the first raw gas into a first raw material having a radical form, wherein generating the plasma is carried out at an enemy below a first ionization enemy of the auxiliary gas such that the auxiliary gas remains substantially neutral when the first raw gas is converted into the first raw material in the radical form;
- supplying the first raw material in the radical form and the auxiliary gas through a connecting passage to an injection portion, wherein the connecting passage is between the reaction space and the injection portion, the connecting passage having a narrower width than the injection portion and the reaction space such that the raw gas and the auxiliary gas are induced to sufficiently stay in the reaction space to convert at least the portion of the first raw gas into the first raw material having the radical form;
- and
- supplying the first raw material in the radical form and the auxiliary gas from the injection portion to the substrate.
