Abstract
A structure includes an active device over an area of a substrate, and a heat spreading isolation structure adjacent the active device. The isolation structure includes a dielectric layer above a heat-conducting layer. The heat-conducting layer may include polycrystalline graphite. The heat-conducting layer provides a heat sink, which provides a high thermal conductivity path for heat with low electrical conductivity. The heat-conducting layer may extend into the substrate. The substrate may include an SOI substrate in which case the heat-conducting layer may extend through the buried insulator thereof.
