    • In accordance with the present invention, there are provided free-radical polymerizable compositions comprising polycyclic olefins, wherein the polycyclic olefins contain little, if any, cyclopentenyl unsaturation. As a result, these olefins are sufficiently reactive with the propagating free-radicals during cure to provide a highly crosslinked thermoset resin. Moreover, invention compositions comprise high molecular weight polycyclic olefins having low volatility. Accordingly, the observed undesirable weight loss upon cure of prior art thermosetting compositions is considerably reduced. Further provided by the present invention are compositions comprising functionalized polycyclic olefin monomers. These functionalized olefin monomers provide additional benefits such as increased adhesion to a variety of surfaces and greater control over glass transition temperatures.
    • 根据本发明,提供了包含多环烯烃的自由基可聚合组合物,其中多环烯烃含有很少(如果有的话)环戊烯基不饱和度。 结果,这些烯烃在固化期间与增长的自由基充分反应,以提供高度交联的热固性树脂。 此外,本发明组合物包含具有低挥发性的高分子量多环烯烃。 因此,在现有技术的热固性组合物固化时观察到的不希望的重量损失显着降低。 本发明进一步提供的是包含官能化多环烯烃单体的组合物。 这些官能化烯烃单体提供额外的益处,例如增加对各种表面的粘附性和对玻璃化转变温度的更大控制。

    • In accordance with the present invention, there is provided a novel composition for attaching a semiconductor device to a substrate. The invention composition comprises liquid polycyanate ester monomer vehicle, electrically conductive filler, and a curing catalyst, preferably in the substantial absence of alkylphenol. The recognition that attach paste compositions are effective without the addition of alkylphenol has the benefit of reducing the cost of preparation, as well as the ease of preparation of die-attach pastes containing electrically conductive filler and polycyanate ester monomer. The incorporation of alkylphenol into die-attach paste compositions has been found to be unnecessary, due to the presence of catalytically active species on the surface of filler flake employed in the preparation of such pastes. Indeed, it is desirable to eliminate alkylphenols from die-attach paste compositions because alkylphenols are acidic species that do not become incorporated into the final polymerized matrix of the cured attach paste. These acidic species can thus leach out, leaving voids in the cured composition and causing corrosion of sensitive electronic parts which come in contact therewith. Optional treatment of filler to render it free of catalytically active metal ions significantly extends the pot life of the composition.
    • 根据本发明,提供了一种用于将半导体器件附着到衬底上的新型组合物。 本发明组合物包含液体聚氰酸酯单体载体,导电填料和固化催化剂,优选基本上不存在烷基酚。 附加糊剂组合物在不加入烷基酚的情况下有效的认识有益于降低制备成本,以及容易制备含有导电填料和聚氰酸酯单体的模片附着浆料。 已经发现,由于在制备这种糊料中使用的填料片表面上存在催化活性物质,因此已经发现将烷基酚引入到模具附着糊剂组合物中是不必要的。 实际上,由于烷基酚是不被引入固化的附着浆料的最终聚合基质中的酸性物质,因此期望从模头附着糊剂组合物中除去烷基酚。 这些酸性物质因此可能被浸出,在固化的组合物中留下空隙并导致与其接触的敏感电子部件的腐蚀。 填充剂的任选处理使其不含催化活性金属离子显着延长了组合物的适用期。
