Abstract:
A method for manufacturing an electronic device comprising the steps of: a) providing two or more apertures in a substrate; b) at least partially filling the two or more apertures with an aperture fill composition comprising one or more cross-linkable polymers having a weight average molecular weight of less than or equal to about 8000 and a value of Mw/Mn of at least 1.5, one or more acid catalysts, one or more cross-linking agents and one or more solvents, wherein the cross-linkable polymers comprise as polymerized units at least one hydroxyl group containing monomer, and wherein the hydroxyl group is at least about 3% wt of the cross-linkable polymers; and c) heating the substrate at a temperature sufficient to at least partially cure the composition.
