A semiconductor device of the MCM type capable of high-speed operation and low power consumption and its manufacturing method are provided. A plurality of semiconductor chips, each having an internal circuit as well as an external connection circuit drawn from the internal circuit, are mounted on the same supporting substrate of this semiconductor device. Semiconductor chips are connected with each other, not by way of the external connection circuits, but directly at a portion between the internal circuits through wiring. This wiring is patterned on an insulating film provided on the supporting substrate and covers the semiconductor chips. Accordingly, through connection holes formed on the insulating film, connection can be established to the internal circuits or the wiring can be formed on the supporting substrate side. If the wiring is formed on the supporting substrate side, the semiconductor chips are to be mounted facing down relative to the supporting substrate.

A multilayer interconnect structure for a semiconductor device. The structure comprises a lower patterned metallization layer, a higher patterned metallization layer, and filled holes for electrically interconnecting these two layers. The two metallization layers are formed out of aluminum or an aluminum alloy by high-temperature aluminum sputtering or aluminum reflow techniques. A suction-preventing layer is formed either at the bottoms of the contact holes or on the surface of the lower metallization layer to prevent the material of the lower metallization layer from being sucked into the overlying contact holes.
