Abstract:
The present invention provides a method of forming a semiconductor structure including the following steps. Firstly, a target layer is formed on a substrate, and a plurality of mandrels is formed on the target layer. Next, a material layer is formed on the target layer to cover the mandrels. Then, an etching process is performed to partially remove each of the mandrel and the material layer covered on each mandrel, to form a plurality of mask. Finally, the target layer is patterned through the masks, to form a plurality of patterns. Through the present invention, each mask comprises an unetched portion of each mandrel and a spacer portion of the material covered on each mandrel, and a dimension of each of the patterns is larger than a dimension of each of the mandrel.

Claim (Index 10):
The method of forming a semiconductor device according to  claim 1 , wherein the etching process comprises providing oxygen gas and nitrogen gas for reaction.
