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 8):
The method of fabricating a mask of  claim 6 , wherein the second material layer is silicon nitride and the first material layer is silicon oxide.
