Systems, devices, and methods for semiconductor device temperature management
First Claim
1. A method of fabricating an IC die that includes at least one coolant fluid reservoir, comprising:
- providing a first substrate layer that includes a first surface and a second surface;
defining at least one recess in said second surface;
filling said at least one recess with a structural material to form at least one reservoir pillar;
etching said first surface to expose said at least one reservoir pillar at said second surface;
etching at said first surface, at least one region adjacent to said at least one reservoir pillar, to form at least one coolant housing portion; and
bonding at least one of said first surface or said second surface to at least one other layer of said IC die.

Abstract
Devices, systems, and methods for semiconductor die temperature management are described and discussed herein. An IC device is described that includes at least one intra-die cooling structure. In an embodiment, the IC device includes a semiconductor die formed of integral device layers and further includes at least one coolant reservoir and at least one coolant channel. In an embodiment, the at least one coolant reservoir and at least one coolant channel are disposed wholly within the semiconductor die. In various embodiments, at least one coolant reservoir and at least one coolant channel are constructed and arranged to circulate coolant fluid in proximity to at least one IC device structure in order to decrease and or normalize an operating temperature of the IC device. In other embodiments, systems and methods for designing and/or fabricating IC die that include at least one intra-die cooling structure are provided herein.
