Abstract

In a method of supplying chemical liquid using an ink jet head including a central portion and peripheral portions each having a first portion and a second portion, a first chemical liquid supply of a chemical liquid may be provided from the central portion onto a substrate, a second chemical liquid supply of the chemical liquid may be provided from the first portion onto a substrate, and a third chemical liquid supply of the chemical liquid may be provided from the second portion onto a substrate. The ink jet head may be moved over the substrate by a length of the peripheral portion. The first chemical liquid supply of the chemical liquid may be provided from the central portion onto a substrate, the second chemical liquid supply of the chemical liquid may be provided from the first portion onto a substrate, and the third chemical liquid supply of the chemical liquid may be provided from the second portion onto a substrate.

Claims

1. A method of supplying chemical liquid using an ink jet head including a central portion and peripheral portions each having a first portion and a second portion, which comprises:

providing a first chemical liquid supply of a chemical liquid from the central portion onto a substrate, providing a second chemical liquid supply of the chemical liquid from the first portion onto a substrate, and providing a third chemical liquid supply of the chemical liquid from the second portion onto a substrate;

moving the ink jet head over the substrate by a length of the peripheral portion; and

providing the first chemical liquid supply of the chemical liquid from the central portion onto a substrate, providing the second chemical liquid supply of the chemical liquid from the first portion onto a substrate, and providing the third chemical liquid supply of the chemical liquid from the second portion onto a substrate.

2. The method of supplying chemical liquid of claim 1, wherein the first chemical liquid supply of the chemical liquid from the central portion is the same as a sum of the second chemical liquid supply of the chemical liquid from the first portion and the third chemical liquid supply from the second portion.

3. The method of supplying chemical liquid of claim 1, wherein the first chemical liquid supply of the chemical liquid from the central portion is greater than the second chemical liquid supply of the chemical liquid from the first portion and the third chemical liquid supply of the chemical liquid from the second portion.

4. The method of supplying chemical liquid of claim 1, wherein the second chemical liquid supply of the chemical liquid from the first portion is greater than the third chemical liquid supply of the chemical liquid from the second portion.

5. The method of supplying chemical liquid of claim 1, wherein the second chemical liquid supply of the chemical liquid from the first portion is less than the third chemical liquid supply of the chemical liquid from the second portion.

6. The method of supplying chemical liquid of claim 1, wherein each of the peripheral portions includes a third portion and the method comprises providing the chemical liquid of a fourth chemical liquid supply of the chemical liquid from the third portion onto the substrate.

7. The method of supplying chemical liquid of claim 6, wherein the first chemical liquid supply of the chemical liquid from the central portion is the same as a sum of the second chemical liquid supply of the chemical liquid from the first portion, the third chemical liquid supply of the chemical liquid from the second portion and the fourth chemical liquid supply of the chemical liquid from the second portion.

8. The method of supplying chemical liquid of claim 6, wherein the first chemical liquid supply of the chemical liquid from the central portion is greater than the second chemical liquid supply of the chemical liquid from the first portion, the third chemical liquid supply of the chemical liquid from the second portion and the fourth chemical liquid supply of the chemical liquid from the second portion.

9. The method of supplying chemical liquid of claim 8, wherein the second chemical liquid supply of the chemical liquid from the first portion is greater than the third chemical liquid supply of the chemical liquid from the second portion, and the third chemical liquid supply of the chemical liquid from the second portion is greater than the fourth chemical liquid supply of the chemical liquid from the third portion.

10. The method of supplying chemical liquid of claim 8, wherein the second chemical liquid supply of the chemical liquid from the first portion is less than the third chemical liquid supply of the chemical liquid from the second portion, and the third chemical liquid supply of the chemical liquid from the second portion is less than the fourth chemical liquid supply of the chemical liquid from the third portion.
