In a cable connector (1) in which a core wire (81a, 81c) of a cable (81) is pressed against a base contact (3) in a predetermined direction (a) intersecting the core wire, a support contact (5) is cooperated with the base contact to clamp the core wire therebetween in the predetermined direction. The base contact is coupled to a base insulator (2). The support contact is coupled to a cover insulator (4) movable against the base insulator in the predetermined direction. A partition wall (42) is formed integral with the cover insulator and positions the core wire to make the core wire face the base contact. When the cover insulator is moved towards the base insulator, the core wire becomes in press contact with the base contact.

Disclosed are a semiconductor integrated circuit device and methods for production thereof. An embodiment of the invention is a semiconductor chip that comprises fuses constituting part of redundancy circuits formed therein, the fuses being made of the same ingredients as those of a CCB bump substrate metal. The fuses are patterned simultaneously during the patterning of the CCB bump substrate metal. This involves forming the fuses using at least part of the ingredients of an electrode conductor pattern in the chip. The cutting regions of the fuses are made of only one of the metal layers constituting the substrate. The principal plane of the semiconductor chip has a fuse protective film formed over at least the cutting regions of the fuses for protection of the latter. In operation, a switch MOSFET under switching control of a redundancy signal is used to select one of two transmission paths, one carrying an address signal or a decode signal, the other carrying a reference voltage. This allows a faulty circuit to be replaced with the corresponding redundancy circuit.

A semiconductor device having improved heat-dissipating characteristics employs a thin insulator film made of diamond, which has excellent thermal conductivity, as an insulator film which is formed on a chip immediately below a heat-dissipating bump electrode. Since the thin diamond film has excellent insulating properties and high thermal conductivity, it is possible to improve heat-dissipating characteristics of even a high-power semiconductor device such as a multichip module. In the case of, particularly, a multichip module, the insulation between a mother chip and a child chip can also be ensured by the presence of the thin diamond film.
