Abstract:
A patterning method includes the following steps. A hard mask layer is formed on a substrate. Mandrels are formed on the hard mask layer. Mask patterns are formed on the mandrels. Each of the mask patterns is formed on one of the mandrels. Spacers are formed on the hard mask layer. Each of the spacers is formed on a sidewall of one of the mandrels and on a sidewall of one of the mask patterns. A cover layer covering the hard mask layer, the spacers and the mask patterns is formed. A planarization process is performed to remove the cover layer on the mask patterns and the spacer and remove the mask patterns. A part of the cover layer remains between the spacers after the planarization process. The mandrels and the cover layer are removed after the planarization process.

Claim (Index 7):
The patterning method according to  claim 1 , wherein the planarization process comprises an etching back process.
