Semiconductor device assembled into a chip size package

摘要

A first insulating film has a first planar surface as a lower surface. A first semiconductor chip is disposed on the first insulating film. A second insulating film is disposed on the first semiconductor chip and the first insulating film and has a second planar surface as an upper surface. A first wiring layer is disposed under the first planar surface. A second wiring layer is disposed on the second planar surface and electrically connected to the first semiconductor chip. A first conductive column penetrates the first insulating film and the second insulating film. A conductor penetrates the second insulating film.
