    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 or via) 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 an 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 method for forming metal wires of a semiconductor device includes the steps of first forming about half of the total metal wires, the wires being arranged at regular intervals, forming sidewall spacers made of insulating materials on the metal wires using an etchback method, and forming the rest of the total wires at spaces between the wires of the first half, again using an etchback process. This results in a wire structure in which a gap between adjacent metal wires is about 0.1 microns in width.

    摘要: A selective metal layer formation method, a capacitor formation method using the same, and a method of forming an ohmic layer on a contact hole and filling the contact hole using the same, are provided. A sacrificial metal layer is selectively deposited on a conductive layer by supplying a sacrificial metal source gas which deposits selectively on a semiconductor substrate having an insulating film and the conductive layer. Sacrificial metal atoms and a halide are formed, and the sacrificial metal layer is replaced with a deposition metal layer such as titanium Ti or platinum Pt, by supplying a metal halide gas having a halogen coherence smaller than the halogen coherence of the metal atoms in the sacrificial metal layer. If such a process is used to form a capacitor lower electrode or form an ohmic layer on the bottom of a contact hole, a metal layer can be selectively formed at a temperature of 500° C. or lower.

    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 an active region of an N-type and a P-type substrate. A landing pad is formed on the peripheral circuit portion at the same time as 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 step coverage of the metal being deposited in the contact hole for the interconnection is enhanced, and the contact resistance is reduced. As a result, the reliability of the semiconductor device is improved.

    摘要: The present invention discloses a method for forming a dielectric film having improved leakage current characteristics in a capacitor. A lower electrode having a surface and a rounded protruding portion is formed on a semiconductor substrate. The surface and the protruding portion define at least one concave area. A chemisorption layer is then formed on the surface and the rounded protruding portion by supplying a first reactant. Also, a physisorption layer is formed on the chemisorption layer from the first reactant. Next, a portion of the physisorption layer is removed and a portion of the physisorption layer is left on the concave area. Subsequently, the chemisorption layer and the portion of the physisorption layer on the concave area react with a second reactant to form a dielectric film on the surface of the lower electrode. The thickness of said dielectric film is greater on the concave area than on the protruding portion, thereby reducing leakage current.

    摘要: A wiring structure of a semiconductor device buries an aperture, for example, a contact hole or via hole. The wiring structure includes a semiconductor substrate, an insulating layer formed on the semiconductor substrate and having an aperture formed therein, a diffusion barrier film formed on the inner sidewalls of the aperture and which has a smooth surface without having grain boundaries made of a refractory metal or refractory metal compound, and a metal layer formed on the diffusion barrier film. The metal layer formed on the smooth sidewalls of the diffusion barrier film is made of a uniformly and continuously formed aluminum film having an excellent step coverage. Accordingly, the method for forming the wiring structure effectively buries a contact hole having a high aspect ratio and enhances the reliability of a manufactured device.

    摘要: A thin film manufacturing method is provided. The method includes the step of chemically adsorbing a first reactant on a substrate by injecting the first reactant into a chamber in which the substrate is loaded. Physisorbed first reactant on the chemically adsorbed first reactant is removed by purging or pumping the chamber. After the first reactant is densely chemically adsorbed on the substrate by re-injecting the first reactant into the chamber, the physisorbed first reactant on the dense chemisorbed first reactant is removed by purging or pumping the chamber. A second reactant is chemically adsorbed onto the surface of the substrate by injecting the second reactant into the chamber. Physisorbed second reactant on the chemisorbed first reactant and the second reactant is removed by purging or pumping the chamber. A solid thin film is formed by chemical exchange through densely adsorbing the second reactant onto the substrate by re-injecting the second reactant into the chamber. According to the present invention, it is possible to obtain a precise stoichiometric thin film having a high film density, since the first reactant and the second reactant are densely adsorbed and the impurities are substantially removed by pumping or purging
