Patent ID: 7936563

Claim:
An integrated-circuit device with a fluidic-cooling channel comprising: a silicon substrate with an integrated circuit, the integrated circuit including a transistor structure that comprises contact elements, at least some of the contact elements of the transistor structure being located in the silicon substrate; and an interconnect stack formed on the silicon substrate, the interconnect stack having electrical interconnect segments on one or more interconnect levels and a dielectric layer sequence with a respective intralevel dielectric layer on a respective associated interconnect level of the one or more interconnect levels, electrically isolating different electrical interconnect segments on the associated interconnect level from each other, wherein the interconnect stack comprises the fluidic-cooling channel that extends to at least one of the one or more interconnect levels of the interconnect stack and through at least one interlevel metallization barrier layer in the interconnect stack, and wherein the fluidic-cooling channel extends between a fluidic-cooling input interface to receive a fluidic cooling medium from an external fluidic-cooling circulation driver and a fluidic-cooling output interface to transmit the fluidic cooling medium to the external fluidic-cooling circulation driver, both of the fluidic-cooling input interface and the fluidic-cooling output interface being provided on a substrate outer face of the silicon substrate or on a stack outer face of the interconnect stack, the substrate outer face of the silicon substrate and the stack outer face of the interconnect stack being on opposite sides of the integrated-circuit device.
