Abstract: Designs and methods of design of the present disclosure utilize various forms of carbon allotropes to form a carbon allotrope structure such as a graphene foam filling the interior cavity of vias that form part of a semiconductor die. The carbon allotrope structure enables heat generated within a GaN-based device region of the semiconductor die to be dissipated away. In a different embodiment, utilizing other forms of carbon allotropes, a carbon allotrope layer such as graphene layers is formed. The carbon allotrope layer is disposed over a frontside surface of the semiconductor die to provide additional heat dissipation paths for the heat generated within the GaN-based device region. The higher thermal conductivity of the carbon allotrope foam and the carbon allotrope layer allows the heat to be dissipated away from heat-generating semiconductor devices forming part of the device region of the semiconductor die.
