  • Abstract
    The temperature field due to a hot spot is investigated using a two-dimensional, an improved two-dimensional, and a three-dimensional analysis. It is shown that if the dimensions of the heat source are less than a critical distance, a two-dimensional approach fails even for substrates with a high-thermal conductivity. A combined model involving a local zooming is proposed.<>
