Abstract:
A semiconductor microcooler is fabricated by forming fins in a semiconductor substrate and forming a metal layer upon the fins. A stacked microcooler may be formed by stacking a plurality of semiconductor microcoolers. The microcoolers may be positioned such that the fins of each microcooler are vertically aligned. The microcoolers may include an inlet passage to accept coolant and an outlet passage to expel the coolant. One or more microcoolers may be thermally connected to an electronic device heat generating device, such as an integrated circuit (IC) chip, or the like. Heat from the electronic device heat generating device may transfer to the one or more microcoolers. A flow of cooled liquid may be introduced through the passages and heat from the one or more microcoolers may transfer to the liquid coolant.

Claim (Index 1):
A method comprising:\n forming a first semiconductor microcooler by removing portions of a first bulk silicon substrate to form a plurality of first silicon fins and a plurality of first fin trenches, wherein each first fin trench separates adjacent first silicon fins, forming a first copper layer upon sidewalls of each of the plurality of first silicon fins, by forming a first bonding layer upon a respective upper surface of each of the first plurality of silicon fins, by forming a first access passage within the first semiconductor microcooler by removing a portion of a first silicon fin and a portion of the bulk silicon substrate adjacent to the portion of the first silicon fin, and forming a first fin trench filler within each of the plurality of first fin trenches and within the first access passage; forming a second semiconductor microcooler by removing portions of a second bulk silicon substrate to form a plurality of second silicon fins and a plurality of second fin trenches, wherein each second fin trench separates adjacent second silicon fins, forming a second copper layer upon sidewalls of each of the plurality of second silicon fins, by forming a second bonding layer upon a respective upper surface of each of the second plurality of silicon fins, forming a second fin trench filler within each of the plurality of second fin trenches; stacking the first microcooler and the second microcooler by vertically aligning the plurality of first fin trenches with the plurality of second fin trenches and connecting the first bonding layer and the second bonding layer; and removing the first fin trench filler and the second fin trench filler; wherein the first access passage allows coolant within one or more first fin trenches to pass through the first semiconductor microcooler to one or more second fin trenches of the second semiconductor microcooler.
