Abstract
Present disclosure relates to IC devices with thermal mitigation structures in the form of metal structures provided in a semiconductor material of a substrate on which active electronic devices are integrated (i.e., front-end metal structures). In one aspect, an IC device includes a substrate having a first face and a second face, where at least one active electronic device is integrated at the first face of the substrate. The IC device further includes at least one front-end metal structure that extends from the first face of the substrate into the substrate to a depth that is smaller than a distance between the first face and the second face. Providing front-end metal structures may enable improved cooling options because such structures may be placed in closer vicinity to the active electronic devices, compared to conventional thermal mitigation approaches.
