    • Disclosed herein are embodiments of electronic package incorporating a thermal interface material (e.g., a metal TIM) that is positioned between a lid and a chip on a substrate. The TIM has a predetermined (i.e., repeatable) minimum thickness and is further registered to the top surface of the chip (i.e., the TIM has an essentially symmetric shape and does not extend vertically along the sidewalls of the chip). Also, disclosed herein are embodiments of a method of forming such an electronic package that uses a hierarchical heating process that cures a lid sealant, thereby securing the lid to the substrate, and then reflows (i.e., melts and cools) the TIM, thereby adhering the TIM to both the chip and lid. This hierarchical heating process ensures that the TIM has the above-mentioned characteristics (i.e., a predetermined minimum thickness and registration to the top surface of the chip) and further provides robust process windows for high-yield, low-cost electronic package manufacturing.
    • 本文公开了包含位于盖和基板上的芯片之间的热界面材料(例如,金属TIM)的电子封装的实施例。 TIM具有预定的(即可重复的)最小厚度,并进一步与芯片的顶表面对准(即,TIM具有基本上对称的形状,并且不沿芯片的侧壁垂直延伸)。 此外,本文公开了形成这样的电子封装的方法的实施例,其使用固化盖密封剂的分层加热工艺,从而将盖固定到基板上,然后使TIM的回流(即,熔化和冷却),从而粘附 TIM到芯片和盖子。 这种分层加热工艺确保TIM具有上述特性(即,预定的最小厚度并且与芯片的顶表面对准),并且进一步提供用于高产量,低成本电子封装制造的稳健的工艺窗口。
