In order to reconcile the cleaving performance and the quality of appearance of an instrument panel for an bag, an instrument panel is provided having a skin member of a single layer structure, a cleaving section formed by a groove provided on the back of the skin member is composed of a longitudinal cleaving section which is substantially linear and a pair of "V " shaped lateral cleaving sections which are ramified respectively from both ends of the longitudinal cleaving section and which open forward and extend obliquely with respect to the direction of extension of the longitudinal cleaving section. Furthermore, where a skin member of a double-layered structure in which at least a cushion layer is disposed on the back of a skin layer, a door member is formed on the back of a skin member, in which a brittle section is created, as one body there with by injection-molding a resin material and a brittle section of the door member facing the brittle section of the skin member.

An instrument panel for an air bag device has a surface member having a first surface component and a second surface component each with backsides. A foamed member is formed on the back sides of the surface member and cleavable by expanding pressure of an air bag of the air bag device where the air bag device is disposed adjacent the foam member. The first surface component and the second surface component respectively having first and second side edge portions with respective first and second engaging portions engaging one another to form an adjoining portion of the surface member whereat the surface member is cleaved by the expanding pressure of the air bag. The first engaging portion included a fitting groove having a generally U-shaped section extending from the backside of the first surface component into the foamed member. The second engaging portion includes a fitting protrusion extending from the backside of the second surface component and adapted to be inserted into the fitting groove. The foamed member is foamed onto the backside of the surface member with the fitting protrusion inserted into the fitting groove such that the fitting groove with the fitting protrusion inserted therein is embedded in the foamed member.

A method of fabricating an instrument panel includes providing a skin which forms a surface of the instrument panel and has side face portions extending rearwardly from a front face portion and providing a panel core having a recess for defining a molding space between the panel core and the skin. The front face portion and the side face portions define a bend angle. The recess of the panel core has peripheral walls for engaging the side face portions and the peripheral walls and a surface of the recess define a regular angle which is less than the bend angle. The bend angle, for instance, is larger than the regular angle by 2.degree. to 8.degree., and preferably by 3.degree. to 5.degree.. The panel core is placed in a first die and the skin is place in a second die such that the side face portions are deflected to fit into the recess of the panel core during mold closing. The dies are closed and a foaming material is injected between the panel core and the skin to integrate the panel core and the skin. The side face portions resiliently engage the peripheral walls to prevent leakage of the foaming material. In an embodiment of the method, a skin holding member is movably provided in the second die for holding the side face portions in position during mold closing. The skin holding member is withdrawn to permit engagement of the side face portions with the peripheral walls after mold closing.

A semiconductor device of this invention has a copper wiring layer, of which a layer, to which a composition including at least one substance selected from the group consisting of ammonia and organic bases is applied, and a silicon-containing insulating film are sequentially superimposed on the copper wiring layer. Accordingly, semiconductor devices having insulating layers which adheres well to the copper serving as the wiring material can be obtained.

摘要:
The bonding conditions for bonding a semiconductor chip to a film substrate are controlled to allow an adhesive positioned right under the junction between the first connection terminal of the film substrate and the bump electrode of a semiconductor chip to be pushed out to form an opening in the adhesive layer. As a result, the junction between the first connection terminal and the bump electrode floats from the upper surface of the adhesive layer and supports the semiconductor chip in the floating state. It follows that is possible to prevent crack occurrence derived from the difference in thermal expansion coefficient in the junction between the first connection terminal and the bump electrode, thereby ensuring a good electrical connection.

A conductive paste is loaded in circular holes made in a reinforcing film of a carrier tape which includes a film substrate and the reinforcing film, followed by applying a heat treatment to the conductive paste to form projecting electrodes consisting of solder. Then, the reinforcing film is peeled off to permit the projecting electrode to project from the film substrate.
