Definitions
- the present invention relates to a copper wiring polishing composition and a technique for polishing a surface of a semiconductor integrated circuit with the polishing composition.
- R represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, or a carboxylic acid group.
- the above polishing composition was polished under the following conditions.
- the ratio of the normal polishing speed to the dishing is approximately 1 at a wiring width of 25 zm or more. It can be seen that the traveling speed is the same. This means that even if the end point of polishing is reached, if polishing is continued as it is, polishing proceeds at the same rate as the previous polishing rate.
- Example 1 the dishing progress rate is almost half or less than the normal polishing rate. This means that the polishing rate of copper decreases after reaching the polishing end point. The polishing end point of the planar copper film is past the polishing end point of the planar copper film at the normal polishing rate. It can be understood that when the wiring is applied, the copper polishing rate is automatically reduced, and the progress of the date erosion can be suppressed.
