  • Patent number: 9066460
    Abstract: Cooled electronic assemblies and methods of fabrication are provided. In one embodiment, the assembly includes a coolant-cooled electronic module with one or more electronic component(s), and one or more coolant-carrying channel(s) integrated within the module, and configured to facilitate flow of coolant through the module for cooling the electronic component(s). In addition, the assembly includes a coolant manifold structure detachably coupled to the electronic module. The manifold structure facilitates flow of coolant to the coolant-carrying channel(s) of the electronic module, and the coolant manifold structure and electronic module include adjoining surfaces. One surface of the adjoining surfaces includes a plurality of coolant capillaries or passages. The coolant capillaries are sized to inhibit, for instance, via surface tension, leaking of coolant therefrom at the one surface with decoupling of the coolant manifold structure and electronic module along the adjoining surfaces.

  • Patent number: 9059135
    Abstract: Nanochannel sensors and methods for constructing nanochannel sensors. An example method includes forming a sacrificial line on an insulating layer, forming a dielectric layer, etching a pair of electrode trenches, forming a pair of electrodes, and removing the sacrificial line to form a nanochannel. The dielectric layer may be formed on insulating layer and around the sacrificial line. The pair of electrode trenches may be etched in the dielectric layer on opposite sides of the sacrificial line. The pair of electrodes may be formed by filling the electrode trenches with electrode material. The sacrificial line may be removed by forming a nanochannel between the at least one pair of electrodes.

  • Publication number: 20140284040
    Abstract: Embodiments of the invention comprise a homogeneous heat spreading cap element in chip packages to facilitate better heat spreading and dissipation. The heat spreading cap comprises a single high-K graphite layer supported by a copper frame for increased stability and reduced thermal warpage during handling and operation while minimizing thermal penalty by reducing the amount of material having a relatively low heat conductivity that is needed in conventional heat spreading caps.
