摘要:
One aspect is a composite board including semiconductor chips in semiconductor device positions and a plastic housing composition partly embedding the semiconductor chips. A mould is provided for surrounding the semiconductor chips with plastic housing composition, the mould having a lower part and an upper part and a moldings cavity and the molding cavity having an upper contact area, which forms an interface with the top side of the plastic housing composition to be applied. The upper contact area is covered with a parting layer having essentially the same surface constitution and the same thermal conductivity as an adhesive film forming an interface with the underside of the plastic housing composition, with the result that a warpage of the composite board of less than 1% is obtained.

A blank and a semiconductor device include a composite panel with semiconductor chips embedded in a plastic package molding compound. The blank includes a composite panel with semiconductor chips arranged in rows and columns in a plastic package molding compound with active upper sides of the semiconductor chips forming a coplanar surface area with the upper side of the composite panel. The blank further includes an orientation indicator impressed into the plastic package molding compound when the semiconductor chips are embedded within the molding compound.
摘要:
A heat treatment method is provided for a panel. The panel includes a plastic housing composition, in which semiconductor chips are embedded by their rear sides and edge sides, and the top sides of the semiconductor chips form a coplanar area with the plastic housing composition. The panel is fixed by its underside on a holder, and a temperature gradient (ΔT) is then generated between top side and the underside of the panel. The temperature gradient (ΔT) is then maintained for at least one delimited or selected time period. The panel is then cooled to room temperature (TR).
