Abstract: Apparatuses and methods for providing thermal pathways from a substrate to a thermal bonding pad. The thermal pathways may be metal extensions of the thermal bonding pad that are disposed in channels formed in a backside passivation layer underneath the thermal bonding pad, and may be in direct contact with an underlying substrate. The thermal pathways may provide improved thermal dissipation from the substrate.
