发明名称 Thermally conductive materials, solder preform constructions, assemblies and semiconductor packages
摘要 A thermally conductive material that includes an alloy which includes indium, zinc, magnesium or a combination thereof is described herein. Also, a semiconductor package comprising a thermal interface material which includes solder and particles dispersed throughout the solder, the particles being of thermal conductivity greater than or equal to about 80 W/m-K is described herein. In one described embodiment, a semiconductor package includes a thermal interface material which includes at least one lanthanide element. In yet another embodiment disclosed herein, a solder preform construction includes a solder and a structure within the solder, the solder being of a first composition and the structure being of a second composition which has a lower melting point than the first composition. In another embodiment disclosed herein, an assembly comprising: a heat spreader; and a solder preform construction bonded to the heat spreader, the solder preform construction including a solder of a first composition, and a region within the solder of a second composition which has a lower melting point than the first composition. Methods of forming layered thermal interface materials and thermal transfer materials include: a) providing a heat spreader component, wherein the heat spreader component comprises a top surface, a bottom surface and at least one heat spreader material; b) providing at least one solder material, wherein the solder material is directly deposited onto the bottom surface of the heat spreader component; and c) depositing the at least one solder material onto the bottom surface of the heat spreader component.
