    Abstract: Abrasive articles containing solid abrasive particles (A) selected from the group consisting of inorganic particles, organic particles and inorganic-organic hybrid particles (al) having an average primary particle size of from 1 to 500 nm as determined by laser light diffraction and having electron donor groups (a2) chemically bonded to their surface are provided. The said solid abrasive particles (A) are distributed throughout or on top of or throughout and on top of a solid matrix (B). A method for manufacturing abrasive articles and a method for processing substrates useful for fabricating electrical and optical devices are provided. The said methods make use of the said abrasive articles.

    Abstract: An aqueous chemical mechanical polishing (CMP) agent (A) comprising solid particles (a1) containing (a11) a corrosion inhibitor for metals, and (a12) a solid material, the said solid particles (a1) being finely dispersed in the aqueous phase; and its use in a process for removing a bulk material layer from the surface of a substrate and planarizing the exposed surface by chemical mechanical polishing until all material residuals are removed from the exposed surface, wherein the CMP agent exhibits at the end of the chemical mechanical polishing, without the addition of supplementary materials, － the same or essentially the same static etch rate (SER) as at its start and a lower material removal rate (MRR) than at its start, － a lower SER than at its start and the same or essentially the same MRR as at its start or － a lower SER and a lower MRR than at its start; such that the CMP agent exhibits a soft landing behavior.
