    Abstract: A method of forming a metal nitride film using chemical vapor deposition (CVD), and a method of forming a metal contact of a semiconductor device using the same, are provided. The method of forming a metal nitride film using chemical vapor deposition (CVD) in which a metal source and a nitrogen source are used as a precursor, includes the steps of inserting a semiconductor substrate into a deposition chamber, flowing the metal source into the deposition chamber, removing the metal source remaining in the deposition chamber by cutting off the inflow of the metal source and flowing a purge gas into the deposition chamber, cutting off the purge gas and flowing the nitrogen source into the deposition chamber to react with the metal source adsorbed on the semiconductor substrate, and removing the nitrogen source remaining in the deposition chamber by cutting off the inflow of the nitrogen source and flowing the purge gas into the deposition chamber. Accordingly, the metal nitride film has low resistivity and a low content of Cl even with excellent step coverage, and it can be formed at a temperature of 500° C. or lower. Also, a deposition speed, approximately 20 Å/cycle, is suitable for mass production.

    Abstract: A semiconductor device and manufacturing method thereof having a diffusion barrier layer formed on a semiconductor wafer, whose surface region is provided with a silylation layer, wherein the silylation layer is formed on the diffusion barrier layer which is formed on the semiconductor wafer, by a plasma process using silicon hydride or by a reactive sputtering method using SiH.sub.4. When the metal layer is formed on the silylation layer, the wettability between the diffusion barrier layer and the metal is enhanced and large grains are formed, thereby increasing the step coverage for the contact hole of the metal layer or for the via hole. Additionally, when heat treatment is performed after the metal layer is formed on the silylation layer, the reflow characteristic of the metal layer becomes good, to thereby facilitate the filling of the contact hole or the via hole easy. When the wiring layer is thus formed, the metal wiring having good reliability can be obtained and the subsequent process is rendered unnecessary.

    Abstract: A wiring structure of semiconductor device and a method for manufacturing the same which fills up a contact hole of below one half micron. An insulating layer is formed on a semiconductor substrate, and a contact hole or a via hole is formed in the insulating layer. On the insulating layer, a first metal is deposited via a CVD method to form a CVD metal layer or a CVD metal plug filling up the contact hole. Then, the thus-obtained CVD metal layer or the CVD metal plug is heat-treated in a vacuum at a high temperature below the melting point of the first metal, thereby planarizing the surface thereof the CVD metal layer. A second metal is deposited via a sputtering method on the CVD metal layer or on the CVD metal plug to thereby form a sputtered metal layer. The contact hole is filled up with the first metal by the CVD method and then a reliable sputtered metal layer is deposited via a sputtering method. The wiring layer can be used for the semiconductor device of the next generation.
