    摘要: The invention relates to a wiring structure for a 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 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 plus is heat-treated in a vacuum at a high temperature below the melting point of the first metal, thereby planarizing the surface of 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 semiconductor devices of the next generation.

    摘要: A method for forming a metal interconnection filing a contact hole or a groove having a high aspect ratio. An interdielectric layer pattern having a recessed region corresponding to the contact hole or the groove is formed on a semiconductor substrate, and a barrier metal layer is formed on the entire surface of the resultant structure where the interdielectric layer pattern is formed. An anti-nucleation layer is selectively formed only on the non-recessed region of the barrier metal layer, thereby exposing the barrier metal layer formed on the sidewalls and the bottom of the recessed region. Subsequently, a metal plug is selectively formed in the recessed region, surrounded by the barrier metal layer, thereby forming a metal interconnection for completely filling the contact hole or the groove having a high aspect ratio. A metal liner may be formed instead of the metal plug, followed by forming a metal layer filling the region surrounded by the metal liner, thereby forming metal interconnection for completely filling the contact hole or groove having a high aspect ratio.

    摘要: A tungsten or other metal layer is chemical vapor deposited using a source gas containing tungsten, a reducing gas and a nitrogen-containing gas. The nitrogen-containing gas can act as a surface roughness reducing gas that reduces the roughness of the tungsten layer compared to a tungsten layer that is chemical vapor deposited using the source gas containing tungsten and the reducing gas, but without using the surface roughness reducing gas. Viewed in another way, the nitrogen-containing gas acts as a growth rate controlling gas that produces uniform growth of the tungsten layer in a plurality of directions compared to a tungsten layer that is deposited using the source gas containing tungsten and the reducing gas, but without using the growth rate controlling gas.

    摘要: A method of forming an interconnection by using a landing pad is disclosed. In a semiconductor device having a memory cell portion and a peripheral circuit portion, a refractory metal is used for the bitline instead of the usual polycide, to concurrently form a contact on each active region of an N-type and a P-type, then a landing pad is formed on the peripheral circuit portion when a bitline is formed on the memory cell portion. In such a process, a substantial contact hole for the interconnection is formed on the landing pad so that an aspect ratio of the contact can be lowered. Accordingly, when forming a metal interconnection, the contact hole for the interconnection is easily filled by Al reflow so that the coverage-step of the metal being depositing in the contact hole for the interconnection is enhanced, the contact resistance is reduced. Further, the reliability of the semiconductor device is improved.

    摘要: A wiring layer of a semiconductor device having a novel contact structure is disclosed. The semiconductor device includes a semiconductor substrate, an insulating layer having an opening (contact hole) and a first conductive layer formed on the insulating layer which completely fills the opening. The first conductive layer does not produce any Si precipitates in a subsequent heat-treating step for filling the opening with the first conductive layer material. The semiconductor device may further include a second conductive layer having a planarized surface on the first conductive layer. This improves subsequent photolithography. An anti-reflective layer may be formed on the second conductive layer for preventing an unwanted reflection during a photo lithography process. The semiconductor device preferably includes a diffusion barrier layer under the first conductive layer and on the semiconductor substrate, on the insulating layer, and on the inner surface of the opening which prevents a reaction between the first conductive layer and the semiconductor substrate or the insulating layer. A method for forming the wiring layer is also disclosed. Providing a semiconductor device with the wiring layer reduces the leakage current by preventing Al spiking. Since the first conductive layer undergoes a heat-treatment step at a temperature below the melting point, while flowing into the opening and completely filling it with the first conductive layer material, no void is formed in the opening. Good semiconductor device reliability is ensured in spite of the contact hole being less than 1 .mu.m in size and having an aspect ratio greater than 1.0.

    摘要: A semiconductor device and manufacturing method thereof having a diffusion barrier layer formed on a semiconductor wafer. The diffusion barrier layer has a surface region provided with a silylation layer which is formed on the diffusion barrier layer by a plasma process using silicon hydride or by a reactive sputtering method using SiH.sub.4. When a 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. When the wiring layer is thus formed, metal wiring having good reliability can be obtained and a subsequent scintering process is rendered unnecessary.
