A leaf spring is disposed between a circuit board and a upper shield. The leaf spring biases a heat sink toward the circuit board through a connecting member. The leaf spring is not electrically connected to the upper shield. According to this structure, an integrated circuit and the heat sink can be contacted with each other with certainty. Further, generation of unnecessary radiation can be suppressed effectively.

Thermal management devices and systems, and corresponding manufacturing methods are described herein. A thermal management device includes a plate having a first surface. The first surface partially defines a chamber of the thermal management device. The thermal management device also includes capillary features disposed on the plate, and walls having a first end and a second end. The walls are disposed on the plate and extend away from the first surface of the plate, at the first end, to the second end. The walls partially define the chamber of the thermal management device. The thermal management device also includes a layer of material disposed on the walls, at the second end of the wall. The layer of material partially defines the chamber.

A semiconductor memory device includes an integrated circuit (IC) chip structure, wherein the IC chip includes a substrate, a memory cell disposed on the substrate, and a local well disposed on the substrate, wherein a conductivity type of the local well is different from a conductivity type of the substrate, a wiring stack structure disposed on the IC chip structure, wherein the wiring stack structure includes a signal transfer pattern connected to the memory cell through a signal interconnector, and a thermal dispersion pattern connected to the local well through a thermal interconnector, and a heat transfer structure connected to the thermal dispersion pattern for transferring heat to the thermal dispersion pattern from a heat source.

A method affixes a heat sink to a module lid. A module lid is mounted to a substrate by use of a lid adhesive. The module lid has a threaded exterior portion. The module lid is thermally interfaced to a die by use of a thermal interface material. The heat sink is then screwed onto a module lid, where the heat sink includes a threaded heat sink base pocket that mates with the threaded exterior portion of the module lid, and wherein the heat sink is screwed down onto the module lid until 1) a solid mechanical and thermal contact is established between the heat sink and the module lid, and 2) an airflow from an air moving device flows unobstructed across vanes on the heat sink.
