    摘要: A heat spreader includes a top surface opposite a bottom surface, a cavity extending from the bottom surface, the cavity defined by a profile having at least two steps such that the cavity includes a first surface spaced from the bottom surface of the cavity by a first distance, a second surface spaced from the bottom surface of the cavity by a second distance, and the first distance being less than the second distance. The heat spreader further includes a lid defined by a thickness extending between the bottom surface of the cavity and the top surface of the heat spreader.

    摘要: A heat spreader including a top surface opposite a bottom surface, a cavity formed within and extending upwardly from the bottom surface, wherein the cavity includes an inner wall extending around the cavity and extending vertically downward from an inner cavity surface of the cavity. The heat spreader further includes an outer periphery extending vertically upward from the bottom surface of the heat spreader and extending around the cavity, and at least one step disposed within the cavity an having a surface that is positioned at a vertical height lower than a vertical height of the inner cavity surface of the cavity.
