Abstract: Examples are disclosed that relate to planarizing substrates without use of an abrasive. One example provides a method of chemically planarizing a substrate, the method comprising introducing an abrasive-free planarization solution onto a porous pad, contacting the substrate with the porous pad while moving the porous pad and substrate relative to one another such that higher portions of the substrate contact the porous pad and lower portions of the substrate do not contact the porous pad, and removing material from the higher portions of the substrate via contact with the porous pad to reduce a height of the higher portions of the substrate relative to the lower portions of the substrate.

In some examples, linear motion may be used for chemically planarizing.

Abstract: The present invention provides a chemical-mechanical polishing slurry for use in removing a barrier layer during the fabrication of a damascene structure. The slurry according to the invention includes an agent that suppresses the rate at which an underlying silicon-containing dielectric layer is removed. In the presently most preferred embodiment of the invention, the agent that suppresses the rate at which an underlying silicon-containing dielectric layer is removed is L-lysine and/or L-arginine. The present invention also provides a method of suppressing the removal rate of an underlying silicon-containing dielectric layer during the chemical-mechanical polishing of a barrier layer in a damascene structure. The method according to the invention includes polishing the barrier layer with a slurry comprising an agent that suppresses the rate at which said underlying silicon-containing dielectric layer is removed.
