Abstract:
A semiconductor half-bridge module (10) comprises a first substrate (28) with at least one metallization layer (34) on at least one side, a first line (38a) of semiconductor chips (24a, 24b) electrically and mechanically bonded to a metallization layer (34) of the first substrate (28), a second line (38b) of semiconductor chips (24a, 24b) electrically and mechanically bonded to a metallization layer (34) of the first substrate (28), and a second substrate (30) mechanically bonded with one side to a metallization layer (34) of the first substrate (28) between the first line (38a) and the second line (38b), the second substrate (30) having at least one metallization layer (34e) on a second opposite side providing a DC contact (22) of the module (10). An electrical contact (26) of the semiconductor chips (24a, 24b) of the first line (38a) and/or of the second line (38b) is directly electrically connected to a metallization layer of the second substrate (30). The semiconductor chips (24a, 24b) form a first switch (14) and a second switch (16) of a half-bridge (12), such that a current between the first switch (14) and the second switch (16) flows below the second substrate (30).

A semiconductor stack arrangement (100, 100') and a power semiconductor module with such stack arrangement (100, 100') is proposed. The stack arrangement (100, 100') comprises a first semiconductor chip (102) with a planar terminal (106) mounted to a side (108) of the first semiconductor chip (102) and a second semiconductor chip (104) with a planar terminal (116) mounted to a side (118) of the second semiconductor chip (104). The stack arrangement (100, 100') further comprises an interposer (128, 128') arranged between the first semiconductor chip (102) and the second semiconductor chip (104), which interposer (128, 128) is adapted for electrically connecting the planar terminal (106) of the first semiconductor chip (102) and the planar terminal (116) of the second semiconductor chip (104). A first side (130) of the interposer (128, 128') is in thermal contact with the planar terminal (106) of the first semiconductor chip (102) and a second side (132) of the interposer (128, 128') is in thermal contact with the planar terminal (116) of the second semiconductor chip (104), and the interposer (128, 128') comprises a at least one channel or a plurality of channels (134) adapted for cooling the first semiconductor chip (102) and the second semiconductor chip (104). The interposer is manufactured from an electrically and thermally conductive material and/or alloy.
