摘要:
A coating composition comprising: a hydrolyzed or partially hydrolyzed alkoxysilane, a solvent, and an arylcyclobutene; is useful in a variety of applications, including coatings for multichip modules, flat panel displays and integrated circuits. The preferred alkoxysilanes correspond to formula (I) wherein R is C1-C6 alkylidene, C1-C6 alkylene, arylene, or a direct bond; Y is C1-C6 alkyl, C2-C6 alkenyl, aryl, 3-methacryloxy, 3-acryloxy, 3-aminoethylamino, or 3-amino; R' is independently in each occurrence C1-C6 alkyl; and Z is C1-C6 alkyl, C2-C6 alkenyl or OR'.

摘要:
A suitable cross-linkable matrix precursor and a poragen can be treated to form a porous cross-linked matrix having a Tg of greater than 300° C. The porous matrix material has a lower dielectric constant than the corresponding non-porous matrix material, making the porous matrix material particularly attractive for a variety of electronic applications including integrated circuits, multichip modules, and flat panel display devices.
摘要:
A composition is comprised of the following: a) a hydrolyzed or partially hydrolyzed silane selected from alkoxysilanes and acyloxysilanes; b) a solvent consisting of an organic liquid or mixture of two or more organic liquids in which component (a) and component (c) are soluble and c) a cross-linking prepolymer, oligomer, resin or mixtures thereof that forms a low dielectric constant cross-linked polyarylene. A coating may be made using the composition wherein the coating is comprised of a cross-linked polymer of a low dielectric cross-linking prepolymer, oligomer, resin or mixture thereof and a hydrolyzed or partially hydrolyzed silane, said coating being adhered to a surface of a substrate wherein said surface is comprised of a first material that is a metal, ceramic or polymer and a second material that is (i) a metal, ceramic, or polymer and (ii) different than the first material.
摘要:
An oligomer, uncured polymer or cured polymer comprising the reaction product of one or more polyfunctional compounds containing two or more cyclopentadienone groups and at least one polyfunctional compound containing two or more aromatic acetylene groups wherein at least some of the polyfunctional compounds contain three or more reactive groups. Such oligomers and uncured polymers may be cured to form cured polymers which are useful as dielectrics in the microelectronics industry, especially for dielectrics in integrated circuits.
