Abstract

A film peeling apparatus that peels a film attached to a substrate includes a chamber, a transfer unit, and first peeling rollers. The transfer unit is disposed in the chamber to transfer the substrate. The first peeling rollers are disposed in the chamber, each of the first peeling rollers includes a first electrostatic chuck to adsorb a first film attached to the substrate. The first peeling rollers roll the adsorbed first film to peel the first film from the substrate.

First claim

What is claimed is:

1. A film peeling apparatus that peels a film attached to a substrate, comprising:
a chamber;
a transfer unit disposed in the chamber to transfer the substrate; and
a first peeling roller disposed in the chamber, the first peeling roller including a first electrostatic chuck to adsorb a first film attached to the substrate,
wherein the electrostatic chuck includes a plurality of first magnets each having a first polarity and a plurality of second magnets each having a second polarity different from the first polarity, and
wherein the first peeling roller rolling the adsorbed first film to peel the first film from the substrate.

2. The film peeling apparatus of claim 1 , wherein the first peeling roller comprises:
a first roller that adsorbs and rolls an upper surface of the first film; and
a second roller facing the first roller such that the first film is disposed between the first and second rollers, and the second roller rolling a lower surface of the first film.

3. The film peeling apparatus of claim 2 , wherein the first peeling roller is spaced apart from the substrate while rolling the first film.

4. The film peeling apparatus of claim 2 , wherein one of the first and second rollers makes contact with the substrate while rolling the first film.

5. The film peeling apparatus of claim 1 , further comprising a second peeling roller disposed in the chamber to face the first peeling roller such that the substrate is disposed between the first peeling roller and the second peeling roller, wherein the second peeling roller rolls a second film that seals the substrate in cooperation with the first film to peel the second film from the substrate.

6. The film peeling apparatus of claim 5 , further comprising:
grip units disposed in the chamber to respectively grip the first and second films peeled from the substrate; and
driving units coupled to the grip units to move the grip units in the chamber.

7. A film peeling apparatus that peels a film attached to a substrate, comprising:
a chamber;
a transfer unit disposed in the chamber to transfer the substrate;
a first peeling roller disposed in the chamber, the first peeling roller rolling a first film attached to the substrate to peel the first film from the substrate, and the first peeling roller including a temperature controller disposed in the first peeling roller, the temperature controller cooling the first peeling roller, and

a connection pipe disposed in the first peeling roller, the connecting pipe connecting the temperature controller to a fluid path disposed in a center of the first peeling roller.

8. The film peeling apparatus of claim 7 , wherein the first peeling roller comprises:
a first roller that rolls an upper surface of the first film; and
a second roller facing the first roller such that the first film is disposed between the first and second rollers, and the second roller rolling a lower surface of the first film,
wherein the temperature controller is disposed in the first roller.

9. The film peeling apparatus of claim 8 , further comprising a fluid supply unit connected to the temperature controller to provide a fluid to the temperature controller,
wherein the temperature controller is formed in the first roller, and the temperature controller extends along a surface of the first roller and has a pipe shape to accommodate the fluid.

10. The film peeling apparatus of claim 8 , further comprising:
grip units disposed in the chamber to respectively grip the first and second films peeled from the substrate; and
driving units coupled to the grip units to move the grip units in the chamber.

11. The film peeling apparatus of claim 7 , further comprising a second peeling roller disposed in the chamber to face the first peeling roller such that the substrate is disposed between the first peeling roller and the second peeling roller, wherein the second peeling roller rolls a second film that seals the substrate in cooperation with the first film to peel the second film from the substrate.

12. The film peeling apparatus of claim 7 , further comprising a fluid pipe which connects the fluid path and a fluid supply unit which supplies cooling water.
