Abstract: A cooling device configured to be mounted in close proximity to an electronic component that is to be cooled is provided. In one aspect, the device includes impingement channels and return channels for guiding a flow of cooling fluid towards and away from a cooled surface of the electronic component. The device also includes a heat exchanger and a pump, so that the flow cycle of a cooling fluid is fully confined within the device itself. The impingement channels, the return channels, and the heat exchanger are integrated in a common housing, which includes an inlet opening and an outlet opening for coupling the device to a refrigerant loop. The pump may be a micropump mounted directly on the housing and coupled to the inlet and outlet openings in the housing. A cooling system including the device and the refrigerant loop is also provided.

Abstract: A micro-electronic component, for example an integrated circuit chip, is provided. In one aspect, the component includes a front-end-of-line (FEOL) portion and a back-end-of-line (BEOL) portion at its front side. A back side power delivery network (PDN) is present at the back side of the component, with via connections connecting the PDN to the FEOL and BEOL portions. The back side PDN includes a “dry part” and a “wet part,” where the dry part includes multiple interconnect levels of the PDN embedded in a dielectric material. The “wet part” includes the remaining PDN levels which are not embedded in a dielectric but which are part of a manifold structure configured to receive therein a flow of cooling fluid in order to remove heat generated by the devices in the FEOL portion.

Abstract: A liquid cooling system for cooling an electronic device comprising a chip or a chip package comprising a chip is described. The liquid cooling system comprises an inlet plenum comprising a coolant feeding channel oriented substantially parallel with the plane of a main surface to be cooled of the chip and a plurality of inlet cooling channels fluidically connected to the coolant feeding channel and arranged vertically for impinging a liquid coolant directly on said main surface of the chip. The vertically oriented inlet cooling channels are substantially parallel to vertically oriented outlet cooling channels and are separated by a thermally isolating material. The liquid cooling system further comprises at least one cavity wherein a plurality of inlet and outlet cooling channels end. The cavity is arranged for allowing interaction between the liquid coolant and the main surface of the chip and thus comprises a heat transfer region.

Abstract: The present disclosure is related to a device for cooling the surface of a semiconductor device such as an integrated circuit or the like, the cooling device comprising a plurality of channels (3?) which are non-parallel to the surface to be cooled, each channel comprising a plurality of separate electrodes (5) or equivalent conducting areas arranged along the length of each channel, the device further comprising or being connectable to means for applying a voltage to the electrodes or conducting areas in each channel according to a sequence, the sequence being such that a droplet (6) of cooling liquid in a channel may be moved from one electrode to the next, thereby transporting the droplet from the top of the channel to the bottom, from where the droplet impinges on the surface to be cooled.
