Patent ID: 8268449

Claim:
The combination of: a substrate having a surface, wherein said substrate is a microelectronic substrate selected from the group consisting of silicon, tungsten, tungsten silicide, gallium arsenide, germanium, tantalum, tantalum nitrite, SiGe, low k dielectric layers, dielectric layers, and ion implant layers; and a layer of a composition adjacent said substrate surface, said composition comprising from about 65-95% by weight on a solids basis of a hydrocarbon resin and from about 4-20% by weight on a solids basis of a rubber dispersed or dissolved in a solvent system, wherein said rubber comprises recurring monomers of ethylene and propylene, and said solvent system comprises at least about 95% by weight of a single solvent, said single solvent percentage by weight being based upon the total weight of the solvent system taken as 100% by weight.
