A semiconductor system having a substrate (101) including a rigid insulating interposer (110) with a high modulus and a top (140) and a bottom (150) low-modulus tape with flip-attached semiconductor chips (120, 130). The assembled chips, with the passive surfaces facing each other, are located in an opening (114) of the interposer, which has a thickness (111) equal to or smaller than the sum of the assembled two chips. Adhesive material (160) holds the tapes parallel to the interposer and the chip surfaces together. Solder balls (180) and discrete components (170) may be attached to the outside surfaces of the tapes. |
