    摘要: A method for fabricating an interconnection structure includes the following steps. Firstly, a substrate having a first conductive layer thereon is provided. Next, an ultra low-k material layer is formed on the substrate. Next, a portion of the ultra low-k material layer is removed, so as to form an opening to expose the first conductive layer. Next, a dry-cleaning process is performed by using gas, so as to clean a surface of the first conductive layer exposed by the opening. The dry-cleaning process is performed at a temperature in a range from the room temperature to 100° C.

    摘要: A method of fabricating a metal gate structure is provided. Firstly, a high-K gate dielectric layer is formed on a semiconductor substrate. Then, a first metal-containing layer having a surface away from the gate dielectric layer is formed on the gate dielectric layer. After that, the surface of the first metal-containing layer is treated to improve the nitrogen content thereof of the surface. Subsequently, a silicon layer is formed on the first metal-containing layer. Because the silicon layer is formed on the surface having high nitrogen content, the catalyzing effect to the silicon layer resulted from the metal material in the first metal-containing layer can be prevented. As a result, the process yield is improved.
