wherein the driving member includes a third cooling member configured to cool the power source,

wherein the first cooling member, the second cooling member, and the third cooling member each include a cooling passage, and

wherein a fluid passing through the third cooling member has a lower temperature than a fluid passing through the first cooling member and the second cooling member.

2 . The driving device of claim 1 ,

wherein the first gap is formed so that the first bracket and the second bracket are separated from each other in a direction parallel to a moving direction of the slider.

3 . The driving device of claim 1 ,

wherein the first gap is formed so that the first bracket and the second bracket are separated from each other in a direction perpendicular to a moving direction of the slider.

4 . The driving device of claim 1 ,

wherein the first bracket has a rectangular shape according to the first gap, and the second bracket is separated from the first bracket in directions parallel to and perpendicular to a moving directions of the slider.

5 . The driving device of claim 1 , further comprising a controller configured to control each of the first to third cooling members to be switched between an operation mode and a non-operation mode.

6 . The driving device of claim 5 ,

wherein the controller is further configured to control the first to third cooling members to operate when the slider moves, and control at least one of the first to third cooling members not to operate when the slider stops.

7 . The driving device of claim 1 ,

wherein the first gap disappears by thermal expansion of each of the first bracket and the second bracket.

8 . The driving device of claim 1 , further comprising at least one inkjet head coupled to the bracket and configured to dispense a chemical liquid toward a substrate.

9 . A head assembly comprising:

a chuck configured to support a substrate;

a driving device including a driving member including a power source;

a slider configured to linearly move according to power supply from the power source;

a guide member configured to provide a movement path to the slider coupled to the slider;

a bracket coupled to the slider; and

at least one inkjet head coupled to the bracket and configured to dispense a chemical liquid toward the substrate,

wherein the bracket is divided into a first bracket and a second bracket separated from each other by a first gap, and includes a first cooling member configured to cool the first bracket and a second cooling member configured to cool the second bracket,

wherein the driving member includes a third cooling member configured to cool the power source,

wherein the first cooling member, the second cooling member, and the third cooling member each include a cooling passage, and

wherein a fluid passing through the third cooling member has a lower temperature than a fluid passing through the first cooling member and the second cooling member.

10 . The head assembly of claim 9 ,

wherein the first gap is formed so that the first bracket and the second bracket are separated from each other in a direction parallel to a moving direction of the slider.

11 . The head assembly of claim 10 ,

wherein the first gap disappears by thermal expansion of each of the first bracket and the second bracket.

12 . The head assembly of claim 9 ,

wherein a temperature of the third cooling member is lower than a temperature of the first cooling member and the second cooling member.

13 . The head assembly of claim 9 , further comprising a controller configured to control each of the first to third cooling members to be switched between an operation mode and a non-operation mode.

14 . The head assembly of claim 13 ,

wherein the controller is further configured to control the first to third cooling members to operate when the slider moves, and control at least one of the first to third cooling members not to operate when the slider stops.

15 . A head assembly comprising:

a chuck configured to support a substrate;

a driving device including a driving member including a power source, a slider configured to linearly move according to power supply from the power source, a guide member configured to provide a movement path to the slider coupled to the slider, and a bracket coupled to the slider;

at least one inkjet head coupled to the bracket and configured to dispense a chemical liquid toward the substrate; and

a controller,

wherein the bracket is divided into a first bracket and a second bracket separated from each other by a first gap, and includes a first cooling member configured to cool the first bracket and a second cooling member configured to cool the second bracket,

wherein the driving member includes a third cooling member configured to cool the power source,

wherein a temperature of the third cooling member is lower than a temperature of the first cooling member and the second cooling member, and

wherein the controller is further configured to control each of the first to third cooling members to switch between an operation mode and a non-operation mode.

16 . The head assembly of claim 15 ,

wherein the first gap disappears by thermal expansion of each of the first bracket and the second bracket.

17 . The head assembly of claim 15 ,

wherein the controller is further configured to control the first to third cooling members to operate when the slider moves, and control at least one of the first to third cooling members not to operate when the slider stops.
