  • Patent number: 7091620
    Abstract: A semiconductor device includes a semiconductor chip formed with connection terminals, an elastic structure interposed between a main surface of the chip and a wiring substrate formed with wirings connected at first ends thereof to the connection terminals, and bump electrodes connected to the other ends of the wirings. The connection terminals may be at a center part or in peripheral part(s) of the chip main surface and both the elastic structure and wiring substrate are not provided at locations of connection terminals. A resin body seals at least the connection terminals and the exposed first ends of wirings (leads). In a scheme in which the connection terminals are located in a peripheral part of the chip main surface, the wiring substrate protrudes beyond the chip boundary where the connection terminals are arranged, and the resin body shape is restricted by the protruding part of the wiring substrate.

  • Patent number: 6940162
    Abstract: In a multi chip module of a structure wherein a plurality of bare or packaged semiconductor chips are mounted on a single wiring board and upper surfaces of the semiconductor chips are covered with a single heat spread plate, the whole space around the semiconductor chips thus sandwiched between the wiring board and the heat spread plate is filled with resin. By so doing, the semiconductor chips are interconnected through the resin, so that even if a stress is exerted on any of the chips, it is dispersed and therefore it is possible to diminish the occurrence of cracks in the chips and the heat spread plate caused by stress concentration. Besides, since the semiconductor chips and the heat spread plate are bonded together with resin, even if there are variations in size of the chips, both can be bonded easily. Further, the bonding of all the chips and the heat spread plate can be done in a single process.
