Abstract:
A patterning method includes the following steps. A second mask layer is formed on a first mask layer. A patterning process is performed to the first mask layer and the second mask layer. The first mask layer is patterned to be a first mask pattern, and the second mask layer is patterned to be a second mask pattern formed on the first mask pattern. A first trim process is performed to the second mask pattern. A width of the second mask pattern is smaller than a width of the first mask pattern after the first trim process. A cover layer is formed covering the first mask pattern and the second mask pattern after the first trim process, and an etching process is performed to the first mask pattern after the step of forming the cover layer.

Claim (Index 5):
The patterning method according to  claim 3 , wherein the oxidation treatment comprises a thermal oxidation treatment, and a process temperature of the oxidation treatment is higher than or equal to 250\u00b0 C.
