Thermal impact of 3D stacking photonic and electronic chips

The study found that 3D integration can lead to significant heat spreading and crosstalk, reducing heater efficiency by up to -43.3% and increasing thermal crosstalk by up to +44.4%. However, optimizing design variables, such as spacing between µbumps and interconnect linewidth, can minimize the thermal penalty of 3D integration.
