Microelectronic assembly having a thermally conductive member with a cavity to contain a portion of a thermal interface material

摘要

A thermally conductive member is placed adjacent a microelectronic die with a thermal interface material between the microelectronic die and a wetting layer formed on a surface of the thermally conductive member. The thermal interface material is heated to cause reflow thereof. The first portion of the thermal interface material is directed by the wetting layer into a first cavity formed in the thermally conductive member. The thermal interface material is then allowed to cool and solidify.
