Abstract
A semiconductor structure containing optimized frontside interlayer dielectrics (ILDs) for a direct backside contact based backside power distribution network is provided. Notably, the frontside ILD materials that are present in the semiconductor structure are optimized such that a frontside ILD layer that is present on a critical circuit path has a thermal conductivity that is less than a thermal conductivity of a frontside ILD layer that is present on a non-circuit path.
