摘要:
A manufacturing device for a synthetic resin hollow molded body molds a first split assembly member, a second split assembly member, and a third split assembly member by a first injection, and joints each of contact portions of the three members with a corresponding contact portion by a second injection. The manufacturing device includes an ejecting mechanism which moves the second split assembly member in a die opening/closing direction, a rotating mechanism which rotates the third split assembly member around a shaft center in the die opening/closing direction, and a sliding mechanism which slides the second split assembly member and the third split assembly member in a direction perpendicular to the die opening/closing direction. According to the manufacturing device, while the dies are open after the first injection, the three members are made different by the ejecting mechanism, and then the three members are made to face one another by the rotation mechanism and the sliding mechanism in the die opening/closing direction.

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.

A redundant data for substituting a sector in the second memory region for a damaged sector in the first memory region is stored in the 1088 sector of the flash memory (1), and a program-instruction for rewriting, the redundant data into the table RAM (7) and for writing a program instruction in a specific sector into a program RAM (3) is stored in the 0 sector of the flash memory (1). Because with this arrangement a separate redundant circuit is unnecessary, costs can be reduced.
