  • Patent number: 7479691
    Abstract: A power semiconductor module having surface-mountable flat external contact areas and a method for producing the same is disclosed. In one embodiment, the top sides of the external contacts form an inner housing plane, on which at least one power semiconductor chip is fixed by its rear side on a drain external contact. An insulation layer covers the top side over the edge sides of the semiconductor chip as far as the inner housing plane whilst leaving free the source and gate contact areas on the top side of the semiconductor chip and also whilst partly leaving free the top sides of the corresponding external contacts. Arranged on the insulation layer is a connecting conductive layer between the source contact areas on the top side of the semiconductor chip and the top sides of the source external contacts, and also a gate connecting layer from the gate contact areas to the top side of the gate external contact.

  • Publication number: 20080067667
    Abstract: The invention relates to a semiconductor device (1) comprising a semiconductor chip stack (2) and a plastic housing (3), and to methods for producing the semiconductor device (1). The semiconductor device (1) is constructed on a device carrier (4), on which a first semiconductor chip (5) is fixed by its rear side (6). At least one second semiconductor chip (8) is adhesively bonded by its rear side (9) on the top side (7) of the first semiconductor chip (5) by means of an adhesive layer (10). A second plastic composition (17) is arranged between a first plastic housing composition (11) of the plastic housing (3) and the edge sides (12, 13) of the adhesive layer and the edge sides (14, 15) of the second semiconductor chip (8) and also the top side (16) of the second semiconductor chip (8) in such a way that the first plastic housing composition (11) has no physical contact with the second semiconductor chip (8) and with the adhesive layer (10).
