金属烧结膜组合物;METAL SINTERING FILM COMPOSITIONS

摘要

本发明系关于视需要使用固体或半固体有机黏合剂制备包含一种或多种金属、一种或多种金属合金、或一种或多种金属与一种或多种金属合金之掺合物之烧结膜。该有机黏合剂可具有助熔官能基；该有机黏合剂可为在组合物中的金属或金属合金烧结时部分或完全分解的物质。在一实施例中，该烧结膜提供于最终用途基板(例如矽晶粒或矽晶圆、或金属电路板或金属箔)上，或该烧结膜提供于载体(例如金属网)上。该制法系藉由在适宜的溶剂中分散金属或金属合金(具有或不具黏合剂)，并将组合物曝露于高温下以蒸发掉该溶剂及部分烧结该金属或金属合金而完成。; the organic binder can be one that will partially or completely decompose upon sintering of the metal or metal alloy in the composition. In one embodiment, the sintering film is provided on an end use substrate, such as a silicon die or wafer, or a metal circuit board or foil, or the sintering film is provided on a carrier, such as a metal mesh. Preparation is accomplished by dispersing the metal or metal alloy in a suitable solvent, with or without a binder, and exposing the composition to high temperature to evaporate off the solvent and partially sinter the metal or metal alloy.
