Abstract

A method of manufacturing an electronic apparatus including a plastic substrate, which can facilitate in separating the electronic apparatus including the plastic substrate from a stage, an electronic apparatus manufactured using the method, and an apparatus including the stage for use in the method. The method includes: preparing a stage on which a plurality of island-shaped separation lubricators are arranged; disposing the plastic substrate on the stage; forming a device on the plastic substrate; and separating the plastic substrate from the stage.

Claims (20)

1. A method of manufacturing an electronic apparatus comprising a plastic substrate, the method comprising:

preparing a stage with a plurality of island-shaped separation lubricators and an anti-peeling member, wherein the preparing of the stage comprises forming the plurality of island-shaped separation lubricators and the anti-peeling member on the stage, the plurality of island-shaped separation lubricators being in a first region on the stage, the anti-peeling member being outside the first region of the island-shaped separation lubricators;

disposing the plastic substrate on the stage with the plurality of island-shaped separation lubricators therebetween;

forming an electronic device on the plastic substrate; and

separating the plastic substrate from the stage, wherein the separating of the plastic substrate comprises separating the plastic substrate from the stage by cutting the plastic substrate along a cutting line that is located between the anti-peeling member and the island-shaped separation lubricators.

2. The method of claim 1 , wherein the preparing of the stage comprises forming the plurality of island-shaped separation lubricators on the stage.

3. The method of claim 1 , wherein an adhesive force between the island-shaped separation lubricators and the stage is greater than an adhesive force between the island-shaped separation lubricators and the plastic substrate.

4. The method of claim 1 , wherein an adhesive force between the plastic substrate and the island-shaped separation lubricators is less than an adhesive force between the plastic substrate and the stage.

5. The method of claim 1 , wherein the stage comprises a glass material.

6. The method of claim 1 , wherein the island-shaped separation lubricators comprises a silicon oxide and/or silicon nitride material.

7. The method of claim 1 , wherein the plastic substrate comprises a polyimide material.

8. The method of claim 1 , wherein the disposing of the plastic substrate comprises forming the plastic substrate on the stage by utilizing slit coating.

9. The method of claim 1 , wherein the anti-peeling member surrounds the first region of the island-shaped separation lubricators.

10. The method of claim 9 , wherein the anti-peeling member comprises a plurality of anti-peeling units spaced apart from one another.

11. The method of claim 1 , wherein an adhesive force between the anti-peeling member and the plastic substrate is greater than an adhesive force between the stage and the plastic substrate.

12. The method of claim 1 , wherein the anti-peeling member comprises a material selected from the group consisting of aluminum oxides, gallium oxides, boron oxides, magnesium oxides, calcium oxides, strontium oxides, and combinations thereof.

13. The method of claim 1 , wherein the anti-peeling member has a band gap between about 4 and about 9 eV.

14. The method of claim 1 , wherein the preparing of the stage comprises:

forming the plurality of island-shaped separation lubricators in the first region on the stage; and

forming the anti-peeling member outside the first region of the island-shaped separation lubricators so that the anti-peeling member surrounds the first region of the island-shaped separation lubricators.
