Panel and semiconductor component having a composite board with semiconductor chips and plastic package molding compound and method for the production thereof
View Patent ↗A panel and a semiconductor component including a composite board with semiconductor chips and plastic package molding compound and a method for the production thereof is disclosed. In one embodiment, the panel includes a composite board with semiconductor chips arranged in rows and columns in a corresponding plastic package molding compound with a plurality of semiconductor component positions. The thickness of the plastic package molding compound corresponds to the thickness of the semiconductor chips so that a coplanar upper side and a coplanar rear side are formed on the composite board. Located on the coplanar rear side of the composite board is a plastic layer whose coefficient of thermal expansion corresponds to the coefficient of thermal expansion of the composite board. Located on the coplanar upper side of the composite board is a wiring structure which has corresponding external contacts.
1. A panel comprising:
a composite board with semiconductor chips arranged in rows and columns in a plastic package molding compound with a plurality of semiconductor component positions,
in which the composite board comprises an upper side and rear side, wherein the plastic package molding compound embeds the edge sides of the semiconductor chips and has a thickness which corresponds to the thickness of the semiconductor chips such that the active upper sides of the semiconductor chips and an upper side of the plastic package molding compound are coplanar with one another and together form the upper side of the composite board and the rear sides of the semiconductor chips and a rear side of the plastic package molding compound are coplanar with one another and together from the rear side of the composite board; and
wherein the panel comprises a plastic layer on the rear side of the composite board and a wiring structure on the upper side of the composite board, and wherein the wiring structure is disposed directly on the active upper sides of the semiconductor chips and directly on the upper side of the plastic package molding compound.
2. The panel as claimed in claim 1 , wherein the coefficient of thermal expansion of the plastic layer on the rear side of the composite board corresponds to the coefficient of thermal expansion of the composite board.
3. The panel as claimed in claim 1 , wherein the panel comprises the shape and profile of a semiconductor wafer.
4. The panel as claimed in claim 1 , wherein the wiring structure on the upper side of the composite board comprises conductor tracks, wherein the conductor tracks extend from contact areas on the active upper sides of the semiconductor chips to extemal contact areas on the plastic package molding compound of the composite board.
5. The panel as claimed in claim 1 , wherein a structured masking lacquer layer is disposed on the wiring structure, leaving external contact areas exposed.
6. The panel of claim 1 , wherein the plastic layer extends across the rear side of the semiconductor chips and the rear side of the plastic package molding compound.
7. The panel as claimed in claim 5 , wherein the external contact areas comprise surface-mountable external contacts.
8. The panel as claimed in claim 7 , wherein the surface-mountable external contacts comprise solder balls.
