Integrated cooling assembly including coolant channel on the backside semiconductor device
Abstract:
The present disclosure provides for integrated cooling systems including backside power delivery and methods of manufacturing the same. An integrated cooling assembly may include a device and a cold plate. The cold plate has a first side and an opposite second side, the first side having a recessed surface, sidewalls around the recessed surface that extend downwardly therefrom to define a cavity, and a plurality of support features disposed in the cavity. The first side of the cold plate is attached to a backside of the device to define a coolant channel therebetween. The cold plate includes a substrate, a dielectric layer disposed on a first surface of the substrate, a first conductive layer disposed between the first surface and the dielectric layer, a second conductive layer disposed on a second surface of the substrate, and thru-substrate interconnects connecting the first conductive layer to the second conductive layer.
