Section: claims

1. A mask for forming a fine pattern, comprising:a first pattern repeating in a first direction;a second pattern arranged between and parallel to the first patterns repeated in the first direction and having a first width W1; anda supplemental pattern disposed between the first pattern and the second pattern, and spaced apart by a first distance D1 in the first direction from the second pattern,wherein a second distance D2 between portions of the supplemental pattern in the first direction is (W1+2×D1). 2. The mask of claim 1, wherein the supplemental pattern is a first supplemental pattern isolated from and spaced apart by the first distance from the second pattern. 3. The mask of claim 2, wherein the first supplemental pattern is disposed at the first distance D1 from a portion of the second pattern on remaining regions of the second pattern. 4. The mask of claim 2, wherein a second width W2 of the first supplemental pattern is the same as the first width W1 of the second pattern. 5. The mask of claim 2, wherein the first supplemental pattern forms a semi-rectangular shape that partially encompasses the second pattern. 6. The mask of claim 5, wherein a second width W2 of the first supplemental pattern is the same as the first width W1 of the second pattern. 7. The mask of claim 1, wherein the supplemental pattern is a second supplemental pattern adjacent the first pattern between the first pattern and the second pattern that is spaced apart from the second pattern by the first distance D1. 8. The mask of claim 7, wherein a distance between the first patterns and the second pattern is greater than the first distance D1 and less than (W1+2×D1). 9. The mask of claim 7, wherein if a third distance D3 between the first patterns and the second pattern is greater than the first distance D1 and less than (D1+W1), then a width W3 of the second supplemental pattern is less than the first distance D1. 10. The mask of claim 7, wherein if a third distance D3 between the first patterns and the second pattern is greater than (D1+W1) and less than (W1+2×D1), then a width W3 of the second supplemental pattern is greater than the first distance D1. 11. A method of forming a mask for forming a fine pattern, the method comprising:forming a first pattern repeatedly on a mask in a first direction;forming a second pattern arranged between and parallel to the first patterns repeated in the first direction and having a first width W1; andforming a supplemental pattern disposed between the first pattern and the second pattern, and spaced apart by a first distance D1 in the first direction from the second pattern,wherein a second distance D2 between portions of the supplemental pattern in the first direction is (W1+2×D1). 12. The method of claim 11, wherein the supplemental pattern is a first supplemental pattern isolated from and spaced apart by the first distance D1 from the second pattern. 13. The method of claim 12, wherein forming the first supplementary pattern comprises:forming a first material layer of a width equal to the first distance D1 on at least one side of the second pattern;forming a second material layer of a width equal to the first width W1 on at least one side of the first material layer; andremoving the first material layer of the first distance D1 and removing the second pattern, to form a first supplemental pattern. 14. The method of claim 13, wherein a distance between the second pattern and the first patterns is greater than or equal to a sum of a width W2 of the first supplemental pattern and twice the first distance D1(W2+2×D1). 15. The method of claim 13, wherein the first supplemental pattern is spaced apart from the second pattern by the first distance D1 along a perimeter of the second pattern. 16. The method of claim 13, wherein the first supplemental pattern forms a semi-rectangular shape that partially encompasses the second pattern. 17. The method of claim 13, further comprising forming the second pattern at an original position thereof after forming the first supplemental pattern. 18. The method of claim 13, wherein a width W2 of the first supplemental pattern is the same as the width W1 of the second pattern. 19. The method of claim 18, wherein a distance between the second pattern and the first patterns is greater than or equal to a sum of the width W1 of the second pattern and twice the first distance D1 (W1+2×D1). 20. The method of claim 11, wherein the supplemental pattern is a second supplemental pattern adjacent the first patterns between the first patterns and the second pattern that is spaced apart from the second pattern by the first distance D1. 21. The method of claim 20, wherein the forming of the second supplemental pattern comprises:providing a material layer between the first pattern and at least one side of the second pattern;removing the first pattern; andremoving a portion of the material layer of a width that is equal to the distance D1 and removing the second pattern, to form a second supplemental pattern. 22. The method of claim 21, wherein a distance between the first patterns and the second pattern is greater than the first distance D1 and is less than a sum of the first width W1 and twice the first distance D1 (W1+2×D1). 23. The method of claim 21, wherein if a third distance D3 between the first patterns and the second pattern is greater than the first distance D1 and less than (D1+W1), then a width W3 of the second supplemental pattern is less than the first distance D1. 24. The method of claim 21, wherein if a third distance D3 between the first patterns and the second pattern is greater than (D1+W1) and less than (W1+2×D1), then a width W3 of the second supplemental pattern is greater than the first distance D1. 25. The method of claim 20, wherein the second supplemental pattern is spaced apart from the second pattern by the first distance D1. 26. The method of claim 20, further comprising forming the second pattern at an original position thereof after forming the second supplemental pattern.
