Abstract: A method for manufacturing a semiconductor structure includes the following steps. At first, a titanium layer is formed on a preformed layer. Then, a first titanium nitride layer is formed on the titanium layer. A first plasma treatment is applied to the first titanium nitride layer such that the first titanium nitride layer has a first N/Ti ratio. A second titanium nitride layer is formed on the first titanium nitride layer. A second plasma treatment is applied to the second titanium nitride layer such that the second titanium nitride layer has a second N/Ti ratio larger than the first N/Ti ratio.
