Abstract:
A method of fabricating a mask includes providing a substrate. A first material layer is disposed on the substrate. Then, the first material layer is partly removed. A second trench is formed between the remaining first material layer. The second trench includes a height. Later, a second material layer is formed to conformally fill in the second trench. The second material layer includes a thickness. The thickness of the second material layer equals the height of the second trench. Finally, part of the second material layer is removed, and the remaining second material layer and the remaining first material layer comprise a second mask.

Claim (Index 1):
A method of fabricating a mask, comprising:\n providing a substrate, wherein a first material layer is disposed on the substrate; forming a first mask to cover the first material layer, wherein the first mask comprises a plurality of sub-masks, and a first trench is disposed between the sub-masks adjacent to each other; removing part of the first material layer by using the first mask as a first protective mask to form a second trench between the part of the first material layer which is not removed, wherein the second trench and the first trench form a third trench, the second trench has a height, and the third trench has two sidewalls and a bottom; forming a second material layer to conformally fill in the third trench, wherein the second material layer comprises a thickness, and the thickness equals the height of the second trench; and removing part of the second material layer, wherein the second material layer which is not removed and the first material layer which is not removed form a second mask.
