Resumen de: WO2025072714A1
Concentrated flowable compositions having a total metal weight of at least about 45 wt% are used to form an electrically conductive material. The compositions include metal particulates such as silver flakes, silver particles and/or silver nanowires, and for embodiments of particular interest, a reducible metal composition such as one or more silver salts. The composition includes an organic precursor that forms a polymeric matrix and includes a dissolved polymer binder, a crosslinkable or polymerizable monomer, oligomer or polymer, or a mixture thereof. The flowable precursor composition can be used to form an electrically conductive structure such as a composite of solid polymer matrix and at least about 45 wt% metal. The composite can have a resistivity of no more than about 5 x 10-3 Ohm-cm. Methods for forming the flowable precursor composition and the composites are described.

This conductive paste includes nickel powder, ceramic powder, an organic binder, and an organic solvent, and the surfaces of nickel particles (10) constituting the nickel powder are coated with sulfur (11) and nickel oxide (12) at a proportion of 79-100%, on average. Preferably, the coverage rate of the sulfur (11) on the surface of each of the nickel particles (10) averages 1-89%, and the coverage rate of the nickel oxide (12) on the surface of each of the nickel particles (10) averages 9-99%. More preferably, the organic binder is included in an amount of 3-7 parts by mass with respect to 100 parts by mass of the nickel powder, and the ceramic powder is included in an amount of 2-18 parts by mass with respect to 100 parts by mass of the nickel powder.
Resumen de: WO2025066107A1
Disclosed in the present invention are an adhesive tape for wafer thinning and a preparation method therefor, and a wafer grinding method. The adhesive tape for wafer thinning comprises an adhesive tape layer, a base film layer, and a conductive coating, which are sequentially stacked, wherein the base film layer and the conductive coating constitute an antistatic base film; the raw materials of the adhesive tape layer comprise an acrylic adhesive, a hardening agent and an antistatic agent, the mass dosage of the hardening agent being 3-4% of that of the acrylic adhesive, and the mass dosage of the antistatic agent being 1-2% of that of the acrylic adhesive; the base film layer is selected from a TPU film; and the conductive coating is selected from a silver nanowire coating. The adhesive tape for wafer thinning of the present invention can be applied to wafer grinding, has good antistatic property, and can effectively inhibit stripping static electricity; in addition, the adhesive tape further has the advantages of being stripped without residue and having water seepage prevention.
