Abstract
The invention relates to a panel and a semiconductor device including a composite plate with semiconductor chips and a plastic packaging compound, and to processes for producing them. For this purpose, the panel having a composite plate has semiconductor chips arranged in rows and columns on a top side of a wiring substrate. The wiring substrate is covered by a plastic packaging compound in a plurality of semiconductor device positions, the rear sides of the semiconductor chips being fixed on the wiring substrate. A plastic packaging compound in the region of the boundary surfaces with the semiconductor chips has a coefficient of thermal expansion which is matched to that of silicon, while the remaining plastic packaging compound has a coefficient of thermal expansion which is matched to that of the wiring substrate and is therefore correspondingly higher.
