摘要:
In a method of manufacturing a semiconductor device where at least one insulating layer structure having a metal wiring constitution is formed to thereby construct a multi-layered wiring arrangement, a first SiOCH layer is produced. Then, a surface section of the first SiOCH layer is treated to change the surface section of the first SiOCH layer to a second SiOCH layer which features a carbon (C) density lower than that of the first SiOCH layer, a hydrogen (H) density lower than that of the first SiOCH layer and an oxygen (O) density higher than that of the first SiOCH layer. Finally, a silicon dioxide (SiO2) layer is formed on the second SiOCH layer.

摘要:
In copper plating using a damascene method, in order to prevent cost rise, dishing, erosion and the like due to the protrusion of plating on the dense wiring area to increase the time for CMP polishing, the copper plating is performed so that the current step of the copper plating has only one step for flowing current in the direction opposite to the direction of growing the plating as shown in FIG. 1. In this time, this opposite direction current step is performed under the condition of a current-time product within a range between 1.0 and 120 mA×sec/cm2.

A manufacturing method of a semiconductor device including a step of forming a via hole in an insulation layer including an organic low dielectric film, such as MSQ, SiC, and SiCN, and then embedding a wiring material in the via hole through a barrier metal. According to this method, a plasma treatment is performed after the via hole is formed and before the barrier metal is deposited, using a He/H2 gas capable of replacing groups (methyl groups) made of organic constituents and covering the surface of the exposed organic low dielectric film (MSQ) with hydrogen, or a He gas capable decomposing the groups (methyl groups) without removing organic low dielectric molecules. As a result, the surface of the low dielectric film (MSQ) is reformed to be hydrophilic and adhesion to the barrier metal is hence improved, thereby making it possible to prevent the occurrence of separation of the barrier metal and scratches.

A method of fabricating a semiconductor device using a PECVD method is provided, which improves the adhesion strength of a deposited dielectric layer to an underlying layer and the reliability of the deposited dielectric layer. After placing a substrate in a chamber, a gas having a thermal conductivity of 0.1 W/mK or greater (e.g., H2 or He) is introduced into the chamber, thereby contacting the gas with the substrate for stabilization of a temperature of the substrate. A desired dielectric layer is deposited on or over the substrate in the chamber using a PECVD method after the step of introducing the gas. As the desired dielectric layer, a dielectric layer having a low dielectric constant, such as a SiCH, SiCHN, or SiOCH layer, is preferably used.
