The present invention provides an aqueous dispersion composition for chemical mechanical polishing which is useful for the manufacture of semiconductor devices, and which for polishing of different types of working films and barrier metal layers formed on semiconductor substrates, can achieve efficient polishing particularly of barrier metal surfaces and can give adequately flattened and high precision finished surfaces. The aqueous dispersion composition for chemical mechanical polishing has properties such that, when polishing a copper film, a tantalum layer and/or tantalum nitride layer and an insulating film under the same conditions, the ratio (R Cu /R Ta ) between the polishing rate of the copper film (R Cu ) and the polishing rate of the tantalum layer and/or tantalum nitride layer (R Ta ) is no greater than 1/20, and the ratio (R Cu /R In ) between the polishing rate of the copper film (R Cu ) and the polishing rate of the insulating film (R In ) is from 5 to 1/5. R Cu /R Ta is preferably no greater than 1/30, especially no greater than 1/40 and most preferably no greater than 1/50, while R Cu /R In is preferably 4-1/4, especially 3-1/3 and more preferably 2-1/2.

The invention provides an aqueous dispersion for chemical mechanical polishing that can limit scratches of a specific size to a specific number. When using the aqueous dispersion for chemical mechanical polishing of an interlayer insulating film with an elastic modulus of no greater than 20GPa as measured by the nanoindentation method, the number of scratches with a maximum length of 1µm or greater is an average of no more than 5 per unit area of 0.01mm 2 of the polishing surface. The aqueous dispersion contains a scratch inhibitor agent and an abrasive.

The present invention provides aqueous dispersion slurry of inorganic particles which is so stable as not to increase in viscosity, gel or sediment even if stored for a long time and therefore can be used as raw materials for, for example, cosmetics, paint, coating materials and lapping slurry for semiconductor wafers, and production method of such aqueous dispersion slurry. The aqueous dispersion slurry according to the present invention has the number of particles whose a particle diameter of 1.3 µm or more is 180,000 or less per mL in terms of 30wt% in concentration, and the average particle diameter thereof is in a range of 0.05 - 0.9 µm. The number of particles having a particle diameter of 1.3 µm or more is counted by using Particle Sensor KS-60, which is a light extinction type sensor for detecting particles, and Particle Counter KL-11, which is a particle counter, both of which made by the same manufacturer, Rion Electro Corp. The average particle diameter is measured by using Laser Particle Analyzer System Par-III made by Otsuka Denshi Co., Ltd.

The object of the present invention is to provide a process for chemical mechanical polishing of semiconductor substrate that is particularly useful for chemical mechanical polishing a wafer having a wiring pattern and an insulating layer having a low dielectric constant is formed between wiring patterns, interlayers in the case of a multi-layer wiring and the like in the process of producing a semiconductor device, and an aqueous dispersion for chemical mechanical polishing which is used in this process. The process for chemical mechanical polishing of a semiconductor substrate of the present invention is that a surface to be polished of the semiconductor substrate is polished under conditions of a rotation speed of a polishing table fixing a polishing pad at the range from 50 to 200 rpm and a pressing pressure of the semiconductor substrate fixed to a polishing head against a polishing pad at the range from 700 to 18,000Pa, by using an aqueous dispersion for chemical mechanical polishing comprising an abrasive and at least one compound selected from the group consisting of polycarboxylic acid having a heterocycle and anhydride thereof, and the polishing pad.
