    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.

    摘要: A process of metal interconnects and a structure of metal interconnect produced therefrom are provided. An opening is formed in a dielectric layer. A metal layer is formed over the dielectric layer filling the opening. A film layer is formed on the metal layer and the dielectric layer. The film layer is reacted with the metal layer during a thermal process, and a protective layer is formed on the surface of the metal layer. The portion of the film layer not reacted with the metal layer is removed to avoid short between the metal layers. The protective layer can protect the surface of the metal layer from being oxidized and thus the stability and the reliability of the semiconductor device can be effectively promoted.

    摘要: A method for forming barrier layers comprises steps of forming a first metal barrier layer covering a first dielectric layer and contacting a conductive layer through a via of the first dielectric layer, forming a barrier layer of metalized materials on the first metal layer, optionally forming a second metal barrier layer on the barrier layer of metalized materials, removing portions of the barrier layer of metalized materials above the via bottom in the first dielectric layer, and leaving the barrier layer of metalized materials remaining on the via sidewall in the first dielectric layer; and forming a second metal layer covering the barrier layer of metalized materials. The accomplished barrier layers will have lower resistivity on the via bottom in the first dielectric layer and they are capable of preventing copper atoms from diffusing into the dielectric layer.

    摘要: A method of fabricating a metal plug. On a semiconductor substrate comprising a MOS device, a dielectric layer, and a via hole penetrating though the dielectric layer, a conformal titanium layer is formed on the dielectric layer and the via hole. A low temperature annealing is formed in a nitrogen environment, so that a surface of the titanium layer is transformed into a first thin titanium nitride layer. A conformal second titanium nitride layer is formed on the first thin titanium nitride layer by using collimator sputtering. A metal layer is formed and etched back on the second titanium nitride layer to form a metal plug.

    摘要: A method for forming a barrier layer inside a contact in a semiconductor wafer is disclosed herein. The forgoing semiconductor wafer includes a dielectric layer on a silicon contained layer. A portion of the silicon contained layer is exposed by the contact. The method mentioned above includes the following steps.First, form a conductive layer on the topography of the semiconductor wafer by a method other than CVD to increase the ohmic contact to the exposed silicon contained layer. Thus a first portion of the conductive layer is formed on the dielectric layer, and a second portion of the conductive layer is formed on the exposed silicon contained layer. Next, remove the first portion of the conductive layer to expose the dielectric layer. Finally, use a chemical vapor deposition (CVD) method to form the barrier layer on the dielectric layer and the first portion of the conductive layer to prevent said silicon contained layer from exposure.
