POLYMERIC ANIZOTROPIC CONDUCTING COMPOSITION GLUING MATERIAL AND GLUING METHOD Russian patent published in 2008 - IPC C09J9/02 C09J163/00 H01L23/48 

FIELD: polymers.

SUBSTANCE: invention relates to technology for semiconductive instrument making, namely to methods and compositions for technology in making semiconductive devices and integral schemes, in particular, to technology for creature of gluing conducting compositions. Invention proposes a material consisting of from organic substances only and wherein at least one substance represents a polymer in the parent material and/or in material after its hardening in the gluing process or formation of gluing layer and comprising at least one active component providing the anisotropic conductivity, and at least one special additive taken in the effective amount. As active component providing anisotropic conductivity the proposed material comprises dielectric component possessing the high polarizability and/or the bistable electronic energetic structure with respect to the process of uptake of an excessive electron owing to the presence of phthalide, sulfophthalide, phthalimidine, o-ketocarboxyl groups, derivatives of o-ketocarboxyl groups and/or labile triarylmethane group. Invention provides creature of polymeric anisotropic conducting composition gluing material with enhanced safety for reproducibility of positive indices, high conductivity and high anisotropy of conductivity in direction perpendicular to the gluing plane.

EFFECT: improved and valuable properties of material.
